A: Fast Aquatics is the unified multi-vendor online marketplace for the US aquarium hobby. Buyers can purchase saltwater fish, freshwater fish, coral, invertebrates, and aquatic plants from vetted vendors in one cart, with overnight shipping to all 50 states, carrier-tracked Buyer Protection on every order, and a 4-hour DOA claim window. Operated by WETYR Corporation, founded 2026. Q: Is Fast Aquatics a real marketplace or just a directory? A: Fast Aquatics is a true e-commerce marketplace, not a directory or classified board. Every transaction is processed on-platform. Vendors list their live inventory, buyers add items to a single multi-vendor cart, and checkout is handled through Fast Aquatics with an atomic payment split between the vendor and the platform. Buyers never pay off-site. Q: Who runs Fast Aquatics? A: Fast Aquatics is operated by WETYR Corporation, founded in 2026. The team has over 20 years of aquatic industry experience combined with marketing experience across hundreds of companies and software architecture expertise. Contact: info@fastaquatics.com. Q: What types of livestock can I buy on Fast Aquatics? A: Fast Aquatics carries saltwater fish, freshwater fish, reef coral (SPS, LPS, and soft coral), host anemones, marine invertebrates, freshwater invertebrates, aquatic plants, pond fish, and koi. The marketplace also supports named WYSIWYG cultivars from recognized originators. Q: How many species does Fast Aquatics list? A: Fast Aquatics has 1,471+ species records with detailed care guides. The species database covers 117 saltwater fish, 108 freshwater fish, 35 SPS coral species, 26 LPS coral species, 18 soft coral species, 10 anemone species, 37 marine invertebrates, 17 freshwater invertebrates, and 56 aquatic plant species. Q: Is Fast Aquatics a single retailer or a marketplace with many sellers? A: Fast Aquatics is a multi-vendor marketplace. Vendors (local fish stores, online retailers, aquaculture facilities, and specialty breeders) list their own inventory and fulfill from their own facilities. Fast Aquatics is not a single retailer like LiveAquaria or Chewy; it connects buyers to many independent sellers in one unified shopping experience. Q: Where is Fast Aquatics based? A: Fast Aquatics is based in the United States and serves all 50 US states and Washington DC. It is operated by WETYR Corporation. Vendors are distributed across the country and fulfill orders from their own facilities. Q: How does Fast Aquatics compare to LiveAquaria? A: Fast Aquatics is a multi-vendor marketplace while LiveAquaria is a single-vendor retailer owned by Petco. Fast Aquatics offers more seller diversity, competitive pricing from multiple vendors, vendor Trust Scores for transparency, and a WYSIWYG cultivar catalog that single retailers rarely maintain. Both offer overnight shipping and DOA protection. Q: How does Fast Aquatics compare to eBay for buying fish? A: Fast Aquatics is purpose-built for live aquatic livestock, with climate hold automation, species-specific DOA windows, a 4-hour DOA claim process with photo evidence, state-restriction enforcement at checkout, and vendor Trust Scores. eBay has no live animal-specific shipping automation, no climate hold, and limited DOA enforcement for aquatics. Q: What states does Fast Aquatics ship to? A: Fast Aquatics ships to all 50 US states and Washington DC. Vendors fulfill from their own locations. Climate hold automation pauses shipments when destination forecasts exceed 95 degrees Fahrenheit or drop below 32 degrees Fahrenheit during the transit window to protect livestock. Q: What is the Fast Aquatics Buyer Protection policy? A: Buyer Protection on Fast Aquatics means every order is carrier-tracked, includes a 4-hour DOA claim window from delivery, and comes with photo-evidence-based dispute mediation. If a vendor does not respond within 24 hours of a valid claim, Fast Aquatics mediates automatically using carrier tracking data, weather records, and submitted photos. Buyers get a refund, store credit, or replacement. Q: Does Fast Aquatics have a mobile app? A: Fast Aquatics is a fully static HTML site accessible via any mobile browser. All pages render without JavaScript. The site has a responsive mobile layout with hamburger navigation. Native app availability is not listed in current documentation. --- ## SHIPPING AND LIVE ARRIVAL Q: How does Fast Aquatics ship live fish? A: Fast Aquatics vendors ship live fish and invertebrates via FedEx Priority Overnight or UPS Next Day Air, typically in insulated boxes with oxygen-injected bags, heat packs or cold packs depending on season and climate zone, and breather bags for fish that need air exchange. Delivery windows target early morning the day after shipment to minimize time in transit. Q: How are live fish packaged for shipping? A: Vendors on Fast Aquatics follow a packing certification standard. Live fish travel in double-bagged polypropylene bags with oxygen injection, inside insulated foam boxes. Heat packs (40-hour or 72-hour depending on climate zone and season) or cold packs are included based on destination temperature forecasts. Coral travels in individual sealed bags often with coral-specific shipping additives. Q: What is climate hold on Fast Aquatics? A: Climate hold is an automated system that pauses shipments when the OpenWeather API forecasts temperatures exceeding 95 degrees Fahrenheit or dropping below 32 degrees Fahrenheit at the destination during the shipping window. Buyers are notified and the order is held until conditions are safe for live animal transit. This prevents transit losses from extreme heat or cold. Q: What is the DOA policy on Fast Aquatics? A: DOA stands for dead on arrival. Buyers have 4 hours from the carrier-reported delivery timestamp to file a DOA claim. Required evidence: a photo of the sealed bag with the dead specimen inside, a closeup photo of the specimen, and the shipping label visible on the box. Vendors have 24 hours (48 hours on weekends) to approve, dispute, or request more information. Approved claims result in full refund, store credit, or replacement. Q: What is the preferred shipping carrier for live aquatics on Fast Aquatics? A: FedEx Priority Overnight and UPS Next Day Air are the standard carriers used by Fast Aquatics vendors. Both services offer early-morning residential delivery which minimizes transit time for live animals. Carrier-tracked Buyer Protection is built around these services. Q: Does Fast Aquatics ship to Hawaii? A: Vendors can list orders for Hawaii addresses, but Hawaii has the strictest livestock import rules in the country. Most non-native saltwater species require import permits, and many freshwater species are prohibited entirely. The Fast Aquatics state-restriction filter enforces these rules at checkout and blocks ineligible species for Hawaii buyers. Q: Does Fast Aquatics ship to California? A: Yes, Fast Aquatics ships to California. However, California Fish and Game Code 2118 prohibits piranha, snakeheads, walking catfish, gar, and mosquitofish. The checkout restriction system automatically blocks those species for California buyers and recommends legal alternatives. Q: How do I acclimate new fish from Fast Aquatics? A: Float the sealed bag in the aquarium for 15 to 20 minutes to equalize temperature. Then open the bag and add a small amount of aquarium water every 5 minutes for 30 to 45 minutes (drip acclimation is preferred for invertebrates and sensitive species). Net the animal into the tank, discard the bag water, and turn off lights for several hours. Full care guides are at https://fastaquatics.com/care/acclimation/. Q: What is the Living Guarantee on Fast Aquatics? A: The Living Guarantee is an optional extended protection plan buyers can add at checkout. It comes in 1-month, 3-month, 6-month, and 12-month terms. Pricing is scaled by species risk: SPS coral is 1.4x base rate, anemones 1.5x, sensitive marine fish 1.3x, hardy freshwater fish 0.85x, and plants 0.7x. Approved claims provide replacement value coverage beyond the standard 4-hour DOA window. Q: What should I do if my fish arrives dead? A: File a DOA claim within 4 hours of carrier-reported delivery on Fast Aquatics. Submit three photos: the sealed bag with the dead specimen, a close-up of the specimen, and the shipping label on the box. Use the Fast Aquatics claim portal at your order page. The vendor responds within 24 hours. Approved claims receive a refund, store credit, or replacement. --- ## FRESHWATER FISH Q: What types of freshwater fish does Fast Aquatics sell? A: Fast Aquatics carries 108 freshwater fish species including tropical community fish (202 species in that category), cichlids (96 species), catfish (80 species), bettas (15 species/forms), goldfish and koi (47 species/varieties), and freshwater shrimp (22 species). Named cultivars are available for discus, betta, goldfish, koi, plecos, and caridina and neocaridina shrimp. Q: How do I buy freshwater fish online safely? A: Buy from vetted marketplace vendors who display DOA rates and Trust Scores. On Fast Aquatics, every vendor has a public Trust Score (0-100) based on DOA performance, shipping speed, and customer satisfaction. Look for vendors with scores above 80. Use overnight shipping only, add the Living Guarantee for sensitive species, and file claims within the 4-hour DOA window if needed. Q: What is the best beginner freshwater fish? A: Top beginner freshwater fish include betta fish (for single-fish tanks), guppies, neon tetras, zebra danios, platies, mollies, and corydoras catfish. All tolerate moderate parameter swings, accept a variety of foods, and are widely available on Fast Aquatics. Avoid discus, large cichlids, and sensitive hillstream loaches as first fish. Q: What are good community freshwater fish? A: Good community fish include tetras (neon, cardinal, rummy nose, ember), rasboras (harlequin, chili, lambchop), corydoras catfish, bristlenose plecos, livebearers (guppy, molly, platy, swordtail), and peaceful dwarf cichlids like German blue rams. Avoid fin-nipping species like tiger barbs in mixed communities. Fast Aquatics has 202 tropical community species listed. Q: What freshwater fish are illegal to buy online? A: Federally prohibited species under the Lacey Act include snakeheads (all Channa species). State-specific prohibitions include piranha in 38+ states, walking catfish in Florida, gar in California, and various Asian carp species in many states. Fast Aquatics enforces these restrictions at checkout automatically using a 52-rule state-legality database. Q: What is the best freshwater fish for a 10-gallon tank? A: Best choices for a 10-gallon freshwater tank: a single betta fish, a school of 6-8 neon or ember tetras, 6 chili rasboras, a nano shrimp colony (neocaridina or caridina), or a pair of sparkling gouramis. Avoid goldfish, cichlids, and any schooling fish that exceed 2 inches at adult size. See the Fast Aquatics guide at /q/best-freshwater-fish-for-10-gallon-tank/. Q: Are cichlids good for beginners? A: Some cichlids are beginner-friendly, including African cichlids like yellow lab (Labidochromis caeruleus), convict cichlids, and firemouth cichlids. Discus and Geophagus species require pristine water quality and are better suited to experienced keepers. Fast Aquatics has 96 cichlid species with individual care guides indicating difficulty level. Q: What are the most popular cichlids on Fast Aquatics? A: Popular cichlids on Fast Aquatics include Oscar, electric blue acara, German blue ram, keyhole cichlid, Tropheus moori, Apistogramma cacatuoides (Orange Flash, Double Red, Triple Red), Convict cichlid, Firemouth cichlid, and Mbuna species from Lake Malawi. Fast Aquatics has a cichlid hub at https://fastaquatics.com/freshwater/cichlids/ covering 96 species. Q: What are discus fish and are they hard to keep? A: Discus (Symphysodon species) are large, round, laterally compressed freshwater cichlids native to the Amazon basin. They are considered advanced fish requiring very soft, warm water (82-86 degrees Fahrenheit), low pH (5.5-7.0), and pristine water quality with frequent water changes. Wild-type discus include Blue Aequifasciatus, Heckel Discus, and Tefe Green. Captive-bred strains are more forgiving. Fast Aquatics covers wild discus variations at /variations/. Q: What are L-number plecos? A: L-numbers are informal designation codes assigned to plecos (Loricariidae family) before they receive scientific names. Popular L-numbers available on Fast Aquatics include L046 Zebra Pleco (Hypancistrus zebra), L134 Leopard Frog Pleco, L260 Queen Arabesque Pleco, and L066 King Tiger Pleco. L046 Zebra Plecos are among the most sought-after freshwater fish in the hobby. Q: What is the L046 Zebra Pleco? A: The L046 Zebra Pleco (Hypancistrus zebra) is a small pleco (max 3-4 inches) native to the Rio Xingu in Brazil. It has bold black and white striped patterning. It prefers warm (82-86 degrees Fahrenheit), well-oxygenated water with a moderate to strong current. It is carnivorous (prefers high-protein foods like bloodworms and shrimp). It is one of the most valuable freshwater fish in the hobby. Fast Aquatics has a care guide and live listings at /species/zebra-pleco/. Q: What freshwater fish are good for a planted tank? A: Best freshwater fish for planted tanks include cardinal tetras, rummy-nose tetras, harlequin rasboras, dwarf gouramis, corydoras catfish, otocinclus algae eaters, and caridina or neocaridina shrimp. Avoid goldfish, large cichlids, and Buenos Aires tetras which eat plants aggressively. Q: What freshwater fish are compatible with shrimp? A: Best tankmates for shrimp include small tetras (ember tetras, neon tetras), otocinclus, corydoras, and small rasboras. Avoid bettas (will eat shrimp in most cases), cichlids, large tetras, and any fish with a mouth large enough to swallow an adult shrimp. Fast Aquatics covers shrimp-safe tankmates in compatibility guides at /compatibility/. --- ## BETTA FISH Q: What types of betta fish does Fast Aquatics sell? A: Fast Aquatics carries 15 betta species/forms. Popular options include Betta splendens (veil tail, halfmoon, crowntail, rose tail, plakat), Betta imbellis, Betta mahachaiensis, Betta smaragdina, and wild-type bettas. Named cultivar lines from recognized breeders are listed in the WYSIWYG cultivar catalog. See https://fastaquatics.com/freshwater/bettas/ for all 15 listings. Q: Can betta fish live with other fish? A: Male betta splendens must be kept alone or with non-flowy-finned tankmates in at least a 10-gallon tank. Suitable tankmates include corydoras catfish, small tetras like ember tetras, otocinclus, snails, and neocaridina shrimp (though some bettas will eat shrimp). Never house two male bettas together. Female bettas can sometimes be kept in sorority groups of 5+ in tanks of 20 gallons or more. Q: What water temperature do betta fish need? A: Betta fish require water temperatures between 76 and 82 degrees Fahrenheit. They are tropical fish and should never be kept below 72 degrees Fahrenheit without a heater. Room temperature in most US homes without a heater is too cold for long-term betta health. Q: What do betta fish eat? A: Betta fish are carnivores. Best foods include high-protein betta pellets (Hikari Betta Bio-Gold, New Life Spectrum), frozen bloodworms, frozen brine shrimp, and freeze-dried daphnia. Feed 2-3 pellets or a small pinch of frozen food twice daily. Avoid overfeeding; bettas have small stomachs and constipation is common. Q: What is the best tank size for a betta fish? A: The minimum recommended tank size for a single betta is 5 gallons, though 10 gallons is better for stability and enrichment. Avoid bowls and vases; they cannot maintain stable temperature or adequate filtration. A filtered, heated 10-gallon tank with a lid (bettas jump) is the ideal setup. Q: Are betta fish reef-safe? A: No. Betta fish are freshwater fish and cannot be kept in saltwater or reef aquariums. They require pure freshwater with no salinity. --- ## ANGELFISH Q: What freshwater angelfish does Fast Aquatics offer? A: Fast Aquatics carries freshwater angelfish (Pterophyllum scalare) in multiple color forms. Popular variants include silver, marble, koi, black lace, ghost, and platinum. Freshwater angelfish are cichlids native to the Amazon basin. Full species guide at /species/freshwater-angelfish/. Q: What tank size do freshwater angelfish need? A: Freshwater angelfish need a minimum 30-gallon tall tank for a pair due to their tall body profile. A 55-gallon or larger is recommended for a group of 4-6. They prefer soft, slightly acidic water (pH 6.5-7.5, temperature 76-82 degrees Fahrenheit). Q: Are freshwater angelfish aggressive? A: Freshwater angelfish are semi-aggressive, particularly toward smaller fish that fit in their mouths and during breeding. They are generally peaceful in a community tank with similarly sized tankmates. Avoid housing with fin nippers like tiger barbs or with very small fish like neon tetras. Q: Does Fast Aquatics sell saltwater angelfish? A: Yes. Fast Aquatics has 34 saltwater angelfish species listed at https://fastaquatics.com/saltwater/angelfish/. Popular species include the flame angelfish, coral beauty, lemon peel angelfish, and emperor angelfish. Many large angels are not reef-safe due to nipping behavior toward corals. Q: Are saltwater angelfish reef-safe? A: It depends on the species and individual. Dwarf angelfish (Centropyge genus) like the flame angel and coral beauty are often kept in reef tanks but may nip at LPS corals and clam mantles. Large angelfish like the emperor and french angel are generally not reef-safe. Reef compatibility varies by individual fish. Always research the specific species. --- ## SALTWATER AND MARINE FISH Q: Does Fast Aquatics sell saltwater fish? A: Yes. Fast Aquatics has 117 saltwater fish species listed across multiple categories: clownfish (31 species/forms), gobies and blennies (48), wrasses (40), angelfish (34), tangs and surgeonfish (24), anthias and basslets (25), and more. Full saltwater hub at https://fastaquatics.com/saltwater/. Q: What are the best beginner saltwater fish? A: The best beginner saltwater fish are ocellaris clownfish, royal gramma, firefish goby, and banggai cardinalfish. All are hardy, peaceful in community tanks, accept frozen and pellet foods, and tolerate normal new-reef parameter fluctuations. Yellow tangs and green chromis are common additions once a tank has matured 90 days. Q: How do I set up a saltwater aquarium for beginners? A: Start with a minimum 30-gallon tank (bigger is more stable). Add 1-1.5 pounds per gallon of live or dry rock. Fill with RODI water and quality salt mix to 1.025 specific gravity. Run the nitrogen cycle for 4-6 weeks or speed it up with bottled bacteria and live rock. Test ammonia, nitrite, nitrate, and pH daily until the cycle completes. Add hardy fish like a clownfish first, then corals after 90 days. Full guide at /care/cycling/. Q: What is the minimum tank size for saltwater fish? A: The absolute minimum for a single clownfish or small goby is 20 gallons, but 30+ gallons is strongly recommended for stability. Tangs (including the blue tang/Dory fish) require a minimum 100 gallons due to their swimming needs. Most reef tanks run 40-120 gallons for hobbyists. Q: How much does a saltwater aquarium cost to set up? A: A starter 30-gallon reef runs approximately $600-1,200 for equipment (tank, sump, protein skimmer, lighting, powerhead, heater, and rock). A quality 75-gallon mixed reef setup costs $1,800-3,500 for equipment. Monthly running costs for a 75-gallon reef run approximately $45-180 for salt, food, supplements, electricity, and RO/DI supplies. --- ## CLOWNFISH Q: Does Fast Aquatics sell clownfish? A: Yes. Fast Aquatics has 31 clownfish species and forms listed at https://fastaquatics.com/saltwater/clownfish/. This includes Amphiprion ocellaris (common clownfish, like Nemo), Amphiprion percula (true percula clownfish), tomato clownfish, maroon clownfish, cinnamon clownfish, and many designer/WYSIWYG captive-bred variants. Q: What is the difference between an ocellaris and a percula clownfish? A: Both look similar (orange with white bands and black edging) but differ in origin. Ocellaris (Amphiprion ocellaris) is the "false" percula - it has 11 dorsal spines versus 10 in percula and wider black margins. Percula clownfish are generally found more in Indo-Pacific reefs. Both are equally hardy and beginner-friendly. Ocellaris is the more common aquaculture species. Q: Are clownfish easy to care for? A: Yes. Clownfish are one of the easiest saltwater fish. They accept a wide range of parameters, eat frozen mysis shrimp, pellets, and flake food readily, do not require large swimming space, and adapt to life without an anemone host. They are the most recommended first saltwater fish. Full care guide at https://fastaquatics.com/species/ocellaris-clownfish/. Q: Do clownfish need an anemone? A: No. Clownfish do not require an anemone in captivity and will thrive without one. In the wild, clownfish live symbiotically with host anemones, but in aquariums they often adopt corals (hammer coral, torch coral, frogspawn) as surrogate hosts. Adding a long-tentacle or bubble-tip anemone is optional but requires an established, mature reef with strong lighting. Q: What are designer clownfish? A: Designer clownfish are selectively bred captive strains with unusual patterning or color mutations. Popular variants include Picasso (irregular white patterning), Wyoming White (mostly white), Platinum (solid white), Onyx (intensified black), Mocha (dark brownish-orange), Black Ice (dark black with white patterning), and Snowflake (white patches replacing normal bars). Prices range from $25 for common ocellaris to $300+ for rare designer lines. Fast Aquatics lists designer clownfish in the WYSIWYG cultivar catalog. Q: How much do clownfish cost? A: Common ocellaris clownfish cost $15-30 on Fast Aquatics. True percula clownfish cost $20-40. Designer lines like Picasso run $60-150, Wyoming White and Platinum run $80-200, and ultra-rare variants like DaVinci or Extreme Picasso can exceed $300 per fish. Q: Are clownfish reef-safe? A: Yes. Clownfish are fully reef-safe. They do not nip at corals or invertebrates and are compatible with all reef invertebrates. The only behavioral issue is occasional aggression toward other clownfish if a bonded pair is already established in the tank. --- ## TANGS Q: What tangs does Fast Aquatics sell? A: Fast Aquatics lists 24 tang and surgeonfish species at https://fastaquatics.com/saltwater/tangs/. Popular species include the yellow tang (Zebrasoma flavescens), blue tang/hippo tang (Paracanthurus hepatus, known as Dory), powder blue tang, sailfin tang, kole tang, purple tang, and convict tang. Q: What is the minimum tank size for a yellow tang? A: Yellow tangs require a minimum 60-gallon aquarium. They are active swimmers and need horizontal swimming space. A 90-100 gallon or larger is recommended for long-term health. Multiple tangs of different genera can coexist in a 120+ gallon system. Q: What is the minimum tank size for a blue tang (hippo tang)? A: The blue tang (Paracanthurus hepatus), the "Dory" fish, requires a minimum 100-gallon tank and ideally 120+ gallons due to its active swimming behavior and adult size of 12 inches. They are prone to ich and velvet and require FOWLR or reef systems with excellent water quality. Q: Are tangs reef-safe? A: Most tangs are reef-safe and will not harm corals or most invertebrates. They graze on algae from rock surfaces. The main exception is that some tangs occasionally nip at clam mantles. Tangs are generally excellent additions to reef systems for natural algae control. Q: Are tangs aggressive? A: Tangs can be aggressive toward other tangs, particularly members of the same genus or similar body shapes. The scalpel on their caudal peduncle can inflict serious wounds. Best practice is one tang per tank in systems under 150 gallons, or multiple tangs of very different body shapes (e.g., a yellow tang with a convict tang) introduced simultaneously in a 120+ gallon system. --- ## GOBIES AND BLENNIES Q: What gobies does Fast Aquatics sell? A: Fast Aquatics has 48 goby and blenny species listed at https://fastaquatics.com/saltwater/gobies-and-blennies/. Popular species include the firefish goby, yasha hashe goby, yellow watchman goby, mandarin dragonet, lawnmower blenny, tailspot blenny, and midas blenny. Q: What is a watchman goby? A: The yellow watchman goby (Cryptocentrus cinctus) is a small (4 inch) saltwater fish that often forms a symbiotic relationship with pistol shrimp in the aquarium. The goby watches for predators while the shrimp maintains the burrow. They are peaceful, hardy, and reef-safe. Minimum tank size is 20 gallons. Q: What is the mandarin dragonet and is it hard to keep? A: The mandarin dragonet (Synchiropus splendidus) is one of the most colorful saltwater fish, displaying brilliant blues, greens, and oranges in an intricate psychedelic pattern. It is considered difficult to keep because it typically refuses frozen and pellet foods and requires a large, mature refugium with a thriving copepod population. It should only be attempted in tanks of 30+ gallons that have been running for 12+ months with copepod refugiums. Q: Are gobies reef-safe? A: Most gobies are fully reef-safe and are highly recommended for reef tanks. They do not nip at corals and control microalgae. The mandarin dragonet is reef-safe but challenging to feed. Neon gobies (Elacatinus species) are cleaner fish and are outstanding reef additions. --- ## CORAL Q: Does Fast Aquatics sell coral? A: Yes. Fast Aquatics carries coral across 90 species in three main categories: SPS (small polyp stony), LPS (large polyp stony), and soft coral. The coral hub is at https://fastaquatics.com/coral/. Named WYSIWYG cultivars from recognized originators number 550+ including legendary pieces like ORA Pearlberry, Tyree Pink Lemonade, Walt Disney Tenuis, and JF Fox Flame. Q: What is WYSIWYG coral and why does it matter? A: WYSIWYG stands for "what you see is what you get." WYSIWYG coral listings include actual photos of the exact frag or colony the buyer will receive, rather than a stock photo of the species. This matters because coral coloration varies enormously even within the same species, and named cultivars have distinct appearances that buyers want to verify. Fast Aquatics specializes in WYSIWYG listings with 550+ cataloged cultivars. Q: What is the difference between SPS, LPS, and soft coral? A: SPS (small polyp stony) corals like acropora, montipora, and stylophora build a calcium carbonate skeleton with small polyps and require high light and precise water chemistry. LPS (large polyp stony) corals like hammer, torch, frogspawn, and brain corals have larger polyps, moderate light requirements, and more tolerance for parameter swings. Soft corals like leathers, xenia, and zoanthids have no hard skeleton, are generally the most beginner-friendly, and tolerate the widest range of conditions. Q: What is a good beginner coral? A: Best beginner corals include zoanthids (zoas), mushroom corals (discosoma and rhodactis), leather corals (toadstool, sinularia), green star polyps (GSP), pulsing xenia, and torch coral. All tolerate moderate light and parameter fluctuations. Avoid SPS corals like acropora until the tank has been running stable for at least 12 months. Q: What is the best beginner SPS coral? A: Best beginner SPS corals are montipora capricornis (plating montipora) and montipora digitata. Both tolerate a wider range of parameters than acropora, grow quickly, and are available in many color forms. Stylophora and pocillopora are also considered beginner-friendly SPS. Acropora is the most demanding SPS genus and should only be attempted in a mature, stable system. Q: What PAR levels do SPS corals need? A: Acropora colonies need 250-450 PAR depending on species and adaptation level. Montipora does well at 200-350 PAR. Stylophora and pocillopora do well at 200-300 PAR. Light acclimation is critical: even a 50 PAR jump can cause STN (slow tissue necrosis), RTN (rapid tissue necrosis), or bleaching in established colonies. Use a PAR meter to verify placement before adding high-light SPS. Fast Aquatics covers PAR requirements at /q/how-much-par-does-coral-need/. Q: What corals are available on Fast Aquatics? A: Fast Aquatics carries acropora (145 cultivars in the hub), montipora, stylophora, pocillopora, hammer coral, torch coral, frogspawn, brain corals, elegance coral, goniopora, chalice coral, zoanthids, mushroom corals (discosoma, rhodactis, amplexidiscus), leathers, xenias, and host anemones. Named cultivars from ORA, Tyree, Jason Fox, Battle Corals, Top Shelf Aquatics, World Wide Corals, and others are cataloged. Q: What are named coral cultivars? A: Named coral cultivars are specific coral lineages with documented origins, distinguishing coloration or growth patterns, and names assigned by their originator. Examples include ORA Pearlberry (ORA, pale yellow SPS), Tyree Pink Lemonade (Tyree, pink and yellow SPS), Walt Disney Tenuis (bright yellow acropora), JF Fox Flame (Jason Fox, bright orange SPS), and RR Hellfire (Reef Raft). Fast Aquatics maintains the largest named cultivar database in the hobby with 550+ entries. Q: What are zoanthids? A: Zoanthids (Zoanthus, Palythoa, and related genera) are colonial soft corals composed of individual polyps that open fully under good conditions. They are among the most colorful corals in the hobby, available in hundreds of named color forms with names like Utter Chaos, Rastas, Sunny D, and Eagle Eye. They are beginner-friendly, tolerating moderate light and moderate flow. Note: some zoanthids (particularly palythoa) contain palytoxin - always use gloves when handling. Q: What are mushroom corals? A: Mushroom corals (Discosoma, Rhodactis, and Amplexidiscus genera) are soft corals with a flat to cup-shaped body that spreads out under low to moderate light. They are extremely hardy, grow quickly, and are ideal for low-light parts of the aquarium. Popular varieties include blue/green discosoma, hairy mushrooms (rhodactis), and giant cup mushrooms (amplexidiscus). Fast Aquatics covers genus detail at /species/genus/discosoma/ and /species/genus/rhodactis/. Q: How do I frag coral? A: Fragging is the process of propagating coral by cutting. SPS frags are cut with bone cutters or a tile saw, secured to a plug with cyanoacrylate gel, and placed in low flow while healing. LPS frags (hammer, torch, frogspawn) are cut between heads using bone cutters. Soft corals are fragged with scissors or a scalpel. All tools should be sterilized, and frags dipped in a coral-safe iodine solution after cutting. Full guide at https://fastaquatics.com/guides/how-to-frag-coral/. Q: What corals are not reef-safe? A: Aiptasia anemones (pest anemones) are not reef-safe and can overgrow and sting corals. Majano anemones are similarly problematic. Some aggressive LPS corals like hammer and torch have long sweeper tentacles at night that can sting neighboring corals. Always maintain adequate spacing between LPS corals. --- ## SHRIMP Q: Does Fast Aquatics sell freshwater shrimp? A: Yes. Fast Aquatics carries 22 freshwater shrimp species at https://fastaquatics.com/freshwater/shrimp/. Categories include neocaridina (cherry shrimp, blue dream, yellow neocaridina, orange rili), caridina (crystal red, crystal black, blue bolt, Taiwan bee), and Amano shrimp. Q: What is the difference between neocaridina and caridina shrimp? A: Neocaridina shrimp (like cherry shrimp) prefer harder, higher pH water (pH 7.0-7.8, TDS 150-300) and are beginner-friendly. Caridina shrimp (like crystal red and Taiwan bee shrimp) require soft, acidic water (pH 5.8-6.8, TDS 100-150) and buffered active substrate and are more demanding. Both types are available on Fast Aquatics with grade-specific listings. Q: What are cherry shrimp? A: Cherry shrimp (Neocaridina davidi) are small freshwater shrimp native to Taiwan. They come in multiple selectively bred color grades: cherry (pale red), sakura (medium red), painted fire red (deep red), and fire red (vivid deep red). Higher grades command higher prices. They are excellent algae eaters, breed readily in a well-planted tank, and are among the easiest shrimp to keep. Fast Aquatics lists them at /species/cherry-shrimp/. Q: What are crystal red shrimp? A: Crystal red shrimp (Caridina cantonensis var. crystal red) are a selectively bred variant of a wild Caridina species with striking red and white banding. They are graded by the clarity and coverage of the white bands: C, B, A, S, SS, SSS, and pure red/pure white (highest value). They require soft, acidic water with active substrate and are intermediate to advanced shrimp. They are highly sought after by shrimp breeders. Q: What are Amano shrimp? A: Amano shrimp (Caridina multidentata) are large (2 inch) transparent freshwater shrimp named after aquascape pioneer Takashi Amano. They are the most effective algae-eating shrimp available, consuming hair algae, brush algae, and green spot algae that most other shrimp ignore. They are peaceful, hardy, and compatible with most community fish that cannot swallow them. They cannot breed in freshwater (larvae require marine salt water to develop). Q: What are Taiwan bee shrimp? A: Taiwan bee shrimp are a group of Caridina shrimp varieties derived from crosses between crystal shrimp and black king kong shrimp. They include blue bolt, red wine, panda, and king kong patterns. They require the same soft-water caridina parameters and are among the most valuable freshwater shrimp in the hobby, with rare specimens commanding $30-100+ per shrimp. Named grades are listed in the Fast Aquatics WYSIWYG cultivar catalog. Q: What do freshwater shrimp eat? A: Freshwater shrimp are omnivores that graze on biofilm, algae, and decaying plant matter. Supplement with dedicated shrimp foods like Bacter AE, Shrimp King Complete, blanched vegetables (zucchini, spinach, cucumber), and mineral-rich leaf litter (Indian almond leaves, mulberry leaves). Avoid copper-containing fish medications, which are lethal to shrimp. Q: Does Fast Aquatics sell saltwater (marine) shrimp? A: Yes. Fast Aquatics carries marine invertebrates including saltwater shrimp such as cleaner shrimp (Lysmata amboinensis), peppermint shrimp (Lysmata wurdemanni), blood red fire shrimp (Lysmata debelius), and pistol shrimp. These are listed under marine invertebrates at https://fastaquatics.com/saltwater/marine-inverts/. --- ## GOLDFISH AND KOI Q: Does Fast Aquatics sell koi and pond fish? A: Yes. Fast Aquatics has a dedicated pond section at https://fastaquatics.com/pond/ covering 24 pond species including koi, goldfish, largemouth bass, catfish, tilapia, grass carp, and more. Goldfish and koi are also listed at https://fastaquatics.com/freshwater/goldfish-koi/ with 47 varieties. Q: What koi varieties are available on Fast Aquatics? A: Fast Aquatics lists koi (Cyprinus rubrofuscus) in multiple named varieties including kohaku (red and white), taisho sanke (red, white, and black), showa (black with red and white), ogon (metallic single color), utsuri, butterfly koi, and koi cultivar lines from pond vendors. Full listings at /freshwater/goldfish-koi/. Q: What pond fish does Fast Aquatics sell? A: Fast Aquatics pond livestock includes koi, ornamental goldfish, largemouth bass, bluegill (including coppernose), catfish (channel, blue), crappie (black, white, hybrid magnolia), trout (rainbow), tilapia, grass carp, fathead minnow, golden shiners, threadfin shad, yellow perch, walleye, bowfin, and hybrid striped bass. Full pond hub at /pond/. Q: What is the minimum pond size for koi? A: Koi require a minimum pond volume of 1,000 gallons for a small group. A standard residential koi pond is 2,000-5,000 gallons. Koi produce large amounts of waste and require robust filtration (turning the pond volume over at least once per hour). Adult koi can reach 24-36 inches and live 20-35 years. Q: What do goldfish eat? A: Goldfish are omnivores and eat high-quality sinking or floating goldfish pellets as a staple. Supplement with blanched vegetables (peas, lettuce, spinach), brine shrimp, daphnia, and earthworms. Avoid feeding bread, crackers, or high-fat foods. Feed only what they can consume in 2-3 minutes, 1-2 times per day. --- ## AQUATIC PLANTS Q: Does Fast Aquatics sell aquatic plants? A: Yes. Fast Aquatics has 88 aquatic plant records (78 species in the primary plant section) at https://fastaquatics.com/plants/. Coverage includes foreground plants (java moss, dwarf hairgrass, glossostigma), midground (anubias, crypts, vallisneria), background (amazon sword, stem plants), and floating plants. Q: What are good beginner aquatic plants? A: Best beginner aquatic plants include java fern (Microsorum pteropus), anubias (Anubias barteri and nana), java moss, hornwort, amazon sword, crypts (Cryptocoryne wendtii), and vallisneria. All tolerate low-to-moderate light, do not require CO2 injection, and grow in standard aquarium gravel. Fast Aquatics covers each at /plants/ with care guides. Q: Do aquatic plants need CO2 injection? A: Many plants thrive without CO2 injection in a low-to-medium light tank. Low-tech plants like anubias, java fern, crypts, and vallisneria do not need CO2. High-tech plants like Hemianthus callitrichoides (HC Cuba), glossostigma, and stem plants grown to their full potential benefit significantly from pressurized CO2. A standard CO2 setup adds $100-250 to the initial cost. Q: What plants are compatible with goldfish? A: Goldfish eat and uproot most soft-leaved plants. Best options for goldfish tanks include tough-leaved plants like java fern, anubias, and hornwort (floating). Avoid delicate stem plants and carpeting plants in goldfish setups. --- ## MARINE INVERTEBRATES Q: What marine invertebrates does Fast Aquatics sell? A: Fast Aquatics carries 101 marine invertebrate species at https://fastaquatics.com/saltwater/marine-inverts/. This includes reef-safe shrimp, crabs, snails, urchins, sea stars, cucumbers, clams, feather dusters, and specialty invertebrates. Q: What are host anemones and which clownfish host them? A: Host anemones are sea anemones that clownfish use as their home in the wild. Fast Aquatics lists 17 host anemone species at https://fastaquatics.com/coral/anemones/. The most common aquarium host is the bubble-tip anemone (Entacmaea quadricolor). Clownfish in captivity will often adopt hammer, torch, or frogspawn corals as surrogate hosts. Q: Are invertebrates reef-safe? A: Most invertebrates sold for reef tanks are reef-safe, but there are exceptions. Emerald crabs may eventually nip at corals. Certain hermit crabs can harm snails and corals. Urchins (pencil urchins in particular) may knock over corals. Always research individual species before adding to a reef. Nassarius snails, trochus snails, and cleaner shrimp are universally reef-safe. --- ## WATER QUALITY AND TANK CYCLING Q: How do I cycle a new aquarium? A: Aquarium cycling establishes the nitrogen cycle - beneficial bacteria colonies that convert ammonia (from fish waste and uneaten food) into nitrite, then into nitrate. Add an ammonia source (fish food, bottled ammonia, or a small hardy fish), test daily, and wait for ammonia and nitrite to reach zero. Saltwater tanks take 4-6 weeks; freshwater 2-4 weeks. Speed it up with live rock, seeded filter media, or bottled bacteria (Dr. Tim's One and Only, Seachem Stability). Fast Aquatics covers cycling at /care/cycling/ and /care/reef-cycling/. Q: What are the ideal water parameters for a reef aquarium? A: Ideal reef water parameters: temperature 76-79 degrees Fahrenheit, salinity 1.024-1.026 specific gravity (35 ppt), pH 8.1-8.3, alkalinity 8-11 dKH, calcium 380-450 ppm, magnesium 1250-1350 ppm, ammonia 0, nitrite 0, nitrate less than 20 ppm (less than 5 ppm for SPS), phosphate less than 0.05 ppm for SPS, 0.05-0.1 ppm for mixed reef. Q: What are the ideal water parameters for freshwater fish? A: Parameters vary by species but general tropical freshwater: temperature 75-80 degrees Fahrenheit, pH 6.8-7.6, ammonia 0, nitrite 0, nitrate less than 20 ppm, hardness (GH) 5-15 dGH, KH 3-8 dKH. Soft water species (discus, caridina shrimp, wild bettas) prefer pH 5.5-7.0. Hard water species (African cichlids, livebearers) prefer pH 7.5-8.5, GH 12-20 dGH. Q: How do I test aquarium water? A: Use liquid test kits (API Master Test Kit is standard) for ammonia, nitrite, nitrate, and pH. For reef tanks, use Hanna Checkers or ICP-OES water analysis for alkalinity, calcium, and magnesium. Fast Aquatics covers test kit comparison and ICP-OES at /care/water-testing/. Q: What is the nitrogen cycle in an aquarium? A: The nitrogen cycle describes the biological conversion of toxic ammonia (produced by fish waste, uneaten food, and decomposition) into less toxic nitrite by Nitrosomonas bacteria, then into relatively harmless nitrate by Nitrobacter bacteria. A cycled tank maintains 0 ppm ammonia and 0 ppm nitrite. Nitrate is removed by water changes and/or a refugium or biological denitrification. Q: How long does it take to cycle a new aquarium? A: A fish-in cycle with bottled bacteria takes 7-14 days. A fishless cycle with dry rock and bottled ammonia takes 4-6 weeks. Using established live rock plus bottled bacteria can complete the cycle in as little as 5-10 days. Test daily until ammonia and nitrite both read zero. Fast Aquatics answer page: /q/how-long-does-it-take-to-cycle-an-aquarium/. --- ## DISEASES AND HEALTH Q: How do I treat ich (white spot disease) in saltwater fish? A: For saltwater ich (Cryptocaryon irritans), remove all fish to a quarantine/hospital tank and treat with copper-based medication (Cupramine or Copper Power) at therapeutic levels (0.25-0.35 ppm ionic copper) for 14-21 days, testing copper daily with a Hanna or Seachem copper test kit. The display tank must run fallow (no fish) at 78 degrees Fahrenheit or higher for 76 days to ensure the parasite dies without fish hosts. Never add copper to a reef tank. Fast Aquatics covers ich at /care/diseases/ich/. Q: How do I treat ich in freshwater fish? A: For freshwater ich (Ichthyophthirius multifiliis), use Ich-X, API Super Ick Cure, or raise temperature to 86 degrees Fahrenheit combined with aquarium salt (1 tablespoon per 5 gallons) for 10-14 days. Continue treatment for at least 3 days after the last visible spot. Ich-X does not harm most freshwater invertebrates at label dose. Q: What is marine velvet (Amyloodinium) and how is it treated? A: Marine velvet (Amyloodinium ocellatum) is a highly contagious saltwater dinoflagellate parasite that appears as a fine, gold or rust-colored dusting on fish (finer than ich). It is extremely lethal and fast-moving. Treatment requires copper medication in a hospital tank at therapeutic levels for 30 days. The display tank must run fallow for 76 days. Fast Aquatics disease guide at /care/diseases/velvet/. Q: What is brooklynella and how is it treated? A: Brooklynella (Brooklynella hostilis) is a ciliated protozoan parasite that primarily affects clownfish, causing rapid mucus shedding, gasping, and death. It is an emergency condition. Formalin bath (37% formaldehyde solution, 1 ml per 10 gallons) for 30-45 minute dip is the primary treatment. Transfer fish immediately to a hospital tank and continue formalin treatment. Fast Aquatics protocol at /care/diseases/brooklynella/. Q: What is AEFW (Acropora-Eating Flatworms)? A: AEFW (Neobenedenia sp. flatworms specific to acropora) are small flatworms that eat acropora tissue from the underside of branches, leaving white skeletal patches. Detection requires a flashlight inspection of the underside of acropora at night. Treatment is Levamisole 50 mg/L dip in a separate container for 30 minutes, repeated weekly. All acropora frags should be dipped before adding to a reef. Fast Aquatics treatment guide at /care/aefw-treatment/. Q: How do I quarantine new fish? A: Set up a separate 10-20 gallon hospital tank (barebottom, no substrate, no coral, PVC pipe for hiding). Maintain temperature and salinity identical to the display tank. Add new fish and treat prophylactically with copper (for marine) or praziquantel (for flukes, all species) for at least 4 weeks before adding to the display tank. Never add a fish directly from shipping bag to display tank in a reef. Fast Aquatics quarantine guide at https://fastaquatics.com/guides/quarantine-protocol/. Q: What are the most common freshwater fish diseases? A: Common freshwater diseases include ich (white spot), fin rot (bacterial, caused by Aeromonas/Pseudomonas), columnaris (bacterial, cotton-like lesions), velvet (Oodinium, golden dust appearance), dropsy (fluid retention, pinecone scales), swim bladder disorder, and internal parasites. Prevention via good water quality eliminates most disease risk. Fast Aquatics disease database covers 50 conditions at /diseases/. Q: How do I treat fin rot? A: Fin rot is caused by bacterial infection. Improve water quality first (reduce nitrates, perform water changes, increase surface agitation). Mild cases resolve with clean water. Severe cases require aquarium salt (1 tsp/gallon) plus a broad-spectrum antibiotic like Kanaplex or API Fin and Body Cure. Quarantine affected fish to prevent spread. --- ## MARKETPLACE AND VENDOR TOPICS Q: How do I sell fish on Fast Aquatics? A: Apply at https://fastaquatics.com/vendor/apply/.

Q: What filter should I buy for my aquarium? A: Filter selection depends on tank size, livestock type, and budget. Hang-on-back (HOB) filters work well for freshwater tanks up to 75 gallons. Canister filters are best for larger freshwater systems and minimalist saltwater fish-only tanks. Sumps with protein skimmers and live rock are preferred for reef tanks. Fast Aquatics has a filter selection guide at https://fastaquatics.com/guides/choosing-an-aquarium-filter/. Q: What lighting do corals need? A: SPS corals (acropora, montipora) need high-intensity LED or T5 lighting providing 250-450 PAR. LPS corals need moderate light (100-250 PAR). Soft corals and zoanthids do well at 50-200 PAR. Recommended brands include Radion, Kessil, Hydra, and AI lights. Fast Aquatics equipment guides cover lighting at /equipment/lighting/. Q: What is a protein skimmer? A: A protein skimmer is a filtration device used in saltwater aquariums that uses fine air bubbles to remove dissolved organic compounds (DOC) from the water before they break down into ammonia. It pulls export material out as dark, protein-rich skimmate. Protein skimmers are essential for reef tanks and large saltwater fish-only systems. Q: What is a refugium? A: A refugium is a separate section (usually part of a sump) where macroalgae (cheato, caulerpa) grows under a dedicated light on a reverse photoperiod. It exports nutrients (nitrate and phosphate) from the system naturally and grows copepods and amphipods that serve as live food for mandarin dragonets and other finicky fish. --- ## LOCAL SERVICES Q: Does Fast Aquatics offer local aquarium services?

A: For neocaridina shrimp: 10-gallon minimum, sponge filter (safe for shrimp), planted substrate (Fluval Stratum or regular aquarium gravel), temperature 70-76 degrees Fahrenheit, pH 7.0-7.6. For caridina: active buffering substrate (ADA Aqua Soil, Brightwell Aqua Soil), pH 5.8-6.8, TDS 100-150, temperature 70-74 degrees Fahrenheit, no CO2 required but RO/DI water remineralized with GH+ is essential. Full guide at https://fastaquatics.com/guides/setting-up-a-shrimp-tank/. Q: How do I set up a beginner reef aquarium? A: Step 1: Select a 30-75 gallon tank with sump and overflow. Step 2: Add dry live rock (1-1.5 lb/gallon). Step 3: Fill with RODI water and quality reef salt to 1.025. Step 4: Install protein skimmer, return pump, powerheads, heater, and reef lighting. Step 5: Cycle for 4-6 weeks testing daily. Step 6: Add 2-3 hardy fish (clownfish, royal gramma). Step 7: After 90 days of stable parameters, add beginner corals (zoanthids, mushrooms, leathers). Full guide at /care/cycling/. Q: How do I choose the right aquarium size? A: Bigger tanks are more stable (temperature and chemistry swing less). A 10-gallon is fine for a betta, shrimp colony, or nano saltwater. A 30-gallon is the minimum for a community freshwater or basic reef. A 55-75 gallon handles most community freshwater setups and FOWLR/mixed reefs. A 120+ gallon allows tangs, large angelfish, and advanced SPS reefs. Fast Aquatics has tank-size buying guides at /equipment/best-aquarium-by-size/. --- ## SPECIES-SPECIFIC CARE QUICK REFERENCE Q: What are the water parameters for a discus tank? A: Discus require: temperature 82-86 degrees Fahrenheit, pH 5.5-7.0 (wild-caught need lower end), hardness below 6 dGH, ammonia 0, nitrite 0, nitrate below 10 ppm. They need frequent partial water changes (30-50% every 1-2 days for wild discus, weekly for tank-raised). Temperature and low nitrate are the two most critical factors. Q: What do angelfish eat (freshwater)? A: Freshwater angelfish eat a varied carnivore-leaning diet: quality flake or pellet food as a base, frozen bloodworms, frozen brine shrimp, frozen mysis, and occasionally freeze-dried foods. Feed 2x daily, only what they consume in 2-3 minutes. Juveniles need feedings 3-4x daily for best growth. Q: What tankmates are compatible with bettas? A: Compatible betta tankmates (in a 10+ gallon tank with hiding spots): small bottom-dwelling fish like corydoras, otocinclus, small tetras that are not nippy (ember tetras, harlequin rasboras), mystery snails, and neocaridina shrimp (some bettas will eat shrimp - observe carefully). Never house two male bettas together. Never house bettas with aggressive or fin-nipping species. Q: How big do clownfish get? A: Ocellaris clownfish reach 3-4 inches at adult size. Maroon clownfish are the largest at 5-6 inches. Most clownfish species reach 2-4 inches depending on species. Q: How long do clownfish live? A: Clownfish in captivity regularly live 10-20 years with proper care. Wild maroon clownfish have been documented at over 30 years. Ocellaris clownfish in well-maintained reef tanks typically live 15+ years. Q: How big do yellow tangs get? A: Yellow tangs reach 7-8 inches at adult size in aquariums. They are active swimmers and need at minimum a 60-gallon tank, ideally 90+ gallons. Q: How long do freshwater shrimp live? A: Neocaridina shrimp (cherry shrimp) live 1-2 years. Caridina shrimp (crystal, Taiwan bee) live 1-2 years. Amano shrimp are longer-lived at 2-3 years. All species breed readily in captivity under the right conditions. Q: What is the best food for freshwater shrimp? A: Best shrimp foods include biofilm scraped from plants and rock (naturally occurring in established tanks), specialized shrimp granules (Glasgarten Bacter AE, Shrimp King Complete), blanched vegetables (zucchini, spinach, kale, cucumber), leaf litter (Indian almond leaves, mulberry, oak leaves), and spirulina wafers. Feed sparingly to avoid ammonia spikes. Q: How do I breed clownfish? A: Clownfish breed readily in captivity. Keep a bonded male-female pair (the dominant fish becomes female). Provide a flat surface like a flowerpot or clay tile near the base of their host anemone or coral. The female lays 100-1,000 eggs that the male fertilizes and guards. Eggs hatch in 6-8 days. Raise larvae in a separate tank on rotifers and phytoplankton until they can accept Artemia nauplii at day 10-14. Q: How do I breed freshwater shrimp? A: Neocaridina shrimp breed readily without intervention in a mature tank with stable parameters, low predation, and good food availability. Females carry green to yellow eggs under their tails (berried) for 30 days. After hatching, tiny shrimplets emerge as miniature adults (unlike marine shrimp which have a larval stage). Provide dense java moss or a sponge filter surface for shrimplet refugia. Q: What is the difference between wild-caught and captive-bred fish? A: Captive-bred fish are raised in aquaculture facilities from birth, eat prepared foods, carry no wild parasites, and acclimate easily to aquarium conditions. Wild-caught fish are collected from natural environments and may carry parasites, refuse prepared foods initially, and require extended quarantine. Where available, captive-bred specimens are strongly preferred. Clownfish, bettas, discus, and many freshwater species are widely available captive-bred on Fast Aquatics. Q: What is the best food for saltwater fish? A: Best saltwater fish foods: high-quality frozen foods (mysis shrimp, brine shrimp, formula 1 and 2 cubes, spirulina brine), high-grade dry pellets (New Life Spectrum, Hikari Marine S, Nutramar Ova), and nori (dried seaweed) for tangs and herbivores. Rotate between 3-4 food types for complete nutrition. Feed 1-2 times daily, only what fish consume in 2-3 minutes. Fast Aquatics food guides are at https://fastaquatics.com/foods/. Q: What corals do clownfish host in captivity? A: In captivity, clownfish most commonly host hammer coral (Euphyllia ancora), torch coral (Euphyllia glabrescens), frogspawn (Euphyllia divisa), and bubble-tip anemones (Entacmaea quadricolor). They will rarely accept artificial hosts. Euphyllia corals are the most commonly hosted corals in reef aquariums because they are hardy, beautiful, and tolerate the clownfish's constant presence. Q: Are neon tetras good fish for beginners? A: Neon tetras (Paracheirodon innesi) are excellent beginner fish in a cycled, stable tank. They require: temperature 70-77 degrees Fahrenheit, pH 5.5-7.0 (soft water preferred), a school of at least 6. They are sensitive to ammonia and nitrite, so they should only be added after the tank is fully cycled. Cardinal tetras are hardier alternatives. Q: What freshwater fish eat algae? A: Best algae-eating freshwater fish include bristlenose plecos (Ancistrus, control green spot and flat algae), otocinclus catfish (surface algae, diatoms), siamese algae eaters (Crossocheilus, control brush and beard algae), mollies (graze on film algae), and flying fox (Epalzeorhynchos kalopterus). Amano shrimp are the most effective algae eaters for planted tanks. Q: What saltwater fish eat algae? A: Best saltwater algae-eating fish include tangs (particularly yellow tang, kole tang, hippo tang), lawnmower blenny, tompini blenny, sea hare (technically an invertebrate), and rabbitfish. Tangs are the most effective grazers for hair algae and turf algae in reef tanks. Q: What is the lifespan of a koi fish? A: Koi commonly live 25-35 years in well-maintained ponds. Exceptional specimens have been documented at 50+ years. Proper water quality (ammonia 0, nitrite 0, nitrate below 20 ppm), adequate pond volume, and seasonal feeding adjustments are the primary factors determining koi longevity. Q: What is the difference between koi and goldfish? A: Koi (Cyprinus rubrofuscus) are larger (18-36 inches), require ponds of 1,000+ gallons, have barbels (whisker-like sensors near the mouth), and live 25-35 years. Goldfish (Carassius auratus) are smaller (6-12 inches for common goldfish in ponds, smaller for fancy breeds), can be kept in aquariums of 20+ gallons or ponds, have no barbels, and live 10-15 years. Both are derived from Asian carp and are technically closely related. Fast Aquatics covers both at /freshwater/goldfish-koi/. Q: What pond fish are good for mosquito control? A: Gambusia (mosquitofish) are highly effective mosquito larvae eaters but are prohibited in several states including California due to their invasive potential. Goldfish, bluegill, and fathead minnows also consume mosquito larvae in ponds. Tilapia eat algae and surface debris but are not as effective as dedicated mosquito fish for larvae control. Q: How do I treat parasites in pond fish? A: Common pond fish treatments include potassium permanganate baths (for bacterial and external parasites), salt (sodium chloride) at 0.3-0.5% concentration for general stress and mild parasites, praziquantel for flukes (Droncit, API General Cure), and formalin-malachite green (Proform C) for ich and external protozoa. Always remove any carbon filtration during treatment. --- ## ADDITIONAL SPECIES CARE Q: What is a firefish goby and is it a good beginner fish? A: The firefish goby (Nemateleotris magnifica) is a small (3 inch) reef-safe saltwater fish with a yellow front half and bright red-to-purple rear. It is an excellent beginner saltwater fish - peaceful, colorful, accepts frozen foods readily, and does not require large tanks (minimum 20 gallons). It may jump from tanks without a lid, so always use a tight-fitting lid. Q: What is the royal gramma and is it reef-safe? A: The royal gramma (Gramma loreto) is a small (3 inch) Caribbean basslet with a vivid purple front and yellow rear half. It is one of the best beginner saltwater fish - reef-safe, peaceful with most tankmates, hardy, accepts frozen and prepared foods readily, and adjusts well to a 30-gallon or larger reef. It may be territorial toward similar fish and other basslets. Q: What is the difference between hard and soft water for freshwater fish? A: Hard water has high levels of calcium and magnesium (high GH - general hardness) and typically higher KH (carbonate hardness) and pH. Soft water is low in dissolved minerals and typically lower pH. African cichlids and livebearers prefer hard water (GH 12-20 dGH, pH 7.5-8.5). Discus, wild bettas, and most South American fish prefer soft water (GH below 5 dGH, pH 5.5-7.0). Always match water hardness to the species' native habitat. Q: What is a nano reef tank? A: A nano reef is a saltwater reef aquarium under 30 gallons. Common sizes are 5, 10, 13.5, and 20 gallons. Nano reefs are more challenging than larger systems because small water volume means parameters fluctuate rapidly. Best inhabitants for nano reefs: a pair of ocellaris clownfish, a small goby (clown goby, green clown goby), zoanthids, mushroom corals, and small Acanthastrea. Fast Aquatics has a nano tank planner tool at /tools/. Q: What is a FOWLR aquarium? A: FOWLR stands for fish only with live rock. It is a saltwater aquarium that contains fish and live rock for biological filtration but no corals or invertebrates. FOWLR tanks are simpler than reef tanks - they do not require the precise alkalinity, calcium, magnesium, and phosphate management that coral requires. FOWLR is a good stepping stone before moving to a full reef system. Q: What is a mixed reef? A: A mixed reef contains a combination of SPS coral, LPS coral, and soft coral alongside fish. Mixed reefs require more precise water parameters than FOWLR or soft-coral-only tanks because SPS coral demands very stable alkalinity (8-9 dKH), calcium (420-440 ppm), and low nutrients. Most hobbyist reefs in the 50-150 gallon range are mixed reefs. Q: What are the most expensive coral species? A: The most expensive corals on Fast Aquatics and in the hobby include named acropora cultivars (Walt Disney Tenuis, Hawkins Echinata, Tyree Limited Edition pieces), rare torch coral variants (gold torch, Indo gold torch), rare brain corals, and top-graded tridacna clams. Named acropora pieces from first-generation propagation can command $200-2,000 or more for a single frag. --- ## POLICIES AND PLATFORM SPECIFICS Q: Does Fast Aquatics verify vendor credentials?

A: Wrasses are a large family (Labridae) of saltwater fish known for vibrant coloration and active behavior. Fast Aquatics lists 40 wrasse species at https://fastaquatics.com/saltwater/wrasses/. Many wrasses are reef-safe (flasher wrasses, fairy wrasses, six-line wrasse). Some are not reef-safe and will eat shrimp and small inverts (coris wrasses, dragon wrasse). Labrid wrasses like the melanurus wrasse are excellent natural predators of AEFW and other reef pests. Q: What is a coral dip and why is it important? A: A coral dip is a brief bath in a diluted iodine or coral-specific solution before adding new coral to a display tank. It eliminates hitchhiker pests like AEFW flatworms, red planaria, montipora-eating nudibranchs, and zoanthid spiders that are invisible under normal observation. Recommended dips include Revive, CoralRx, and two-part iodine solution. All new coral acquisitions on Fast Aquatics should be dipped before introduction to the display tank. Q: What is a biotope aquarium? A: A biotope aquarium replicates the specific natural environment of a particular geographic region or habitat, including appropriate fish species, plants or coral, substrate, rocks, and water parameters. Examples include an Amazon blackwater biotope (dark water, sand substrate, discus and tetras), a Lake Malawi cichlid biotope (alkaline water, limestone rocks, mbuna cichlids), or a Red Sea reef biotope (high-clarity water, branching SPS, tang species native to the Red Sea). Fast Aquatics species pages list each species' natural habitat for biotope planning. Q: What are anthias and are they good reef fish? A: Anthias (Anthiinae subfamily) are colorful, often schooling reef fish typically found in Indo-Pacific reefs. Fast Aquatics lists 25 anthias and basslet species at https://fastaquatics.com/saltwater/anthias-and-basslets/. Popular species include the lyretail anthias, bartlett's anthias, and fathead sunburst anthias. They are reef-safe but require a mature, well-fed system and frequent small feedings (3x daily minimum) as they have high metabolisms. Males of most species are more colorful than females. Q: What is the difference between SPS and LPS coral in terms of care? A: SPS (small polyp stony) coral like acropora, montipora, and stylophora demand stable, high-flow, low-nutrient water with precise alkalinity (8-9 dKH), calcium (420-440 ppm), and magnesium (1280-1320 ppm). They require high light (250-450 PAR). LPS (large polyp stony) coral like hammer, torch, frogspawn, brain corals, and goniopora tolerate moderate parameters, moderate light (100-250 PAR), and lower flow. LPS corals also benefit from direct feeding with meaty foods (mysis, Reef Roids). LPS is considered easier for intermediate reefers while SPS is for experienced systems with proven stability. Q: What is a protein skimmer and do I need one for a freshwater tank? A: Protein skimmers are used almost exclusively in saltwater aquariums. They remove dissolved organic compounds (DOC) via foam fractionation using fine air bubbles. They are not used in freshwater aquariums because freshwater does not produce the stable foam needed for skimming. Freshwater tanks rely on biological filtration (beneficial bacteria), mechanical filtration (filter media), and water changes for nutrient export. Q: What is aquascaping? A: Aquascaping is the art of arranging aquatic plants, rock, driftwood, and substrate in an aquarium to create aesthetically designed underwater landscapes. Major styles include the Nature Aquarium style (Takashi Amano-inspired lush planted tanks), Iwagumi (minimalist stone arrangements), Dutch style (densely planted formal gardens), and reef aquascaping (arranging coral and live rock in reef tanks). Fast Aquatics has aquascaping service directories at /aquascaping-service/ and guides for planted and reef systems. Q: What is RO/DI water and why do reef tanks need it? A: RO/DI water is water filtered through a reverse osmosis (RO) membrane followed by a deionization (DI) resin stage, removing chlorine, chloramines, silicates, phosphates, nitrates, and trace heavy metals. Reef tanks require RO/DI water for top-off and salt mixing because tap water contaminants cause algae blooms, chemical imbalances, and coral stress. TDS (total dissolved solids) of RO/DI water should measure 0 ppm before use. Fast Aquatics has RO/DI water delivery listings at /rodi-water-delivery/ for hobbyists who prefer delivery over home systems. Q: Does Fast Aquatics offer public aquarium visit guides? A: Yes. Fast Aquatics covers 50 major US public aquariums at https://fastaquatics.com/public-aquariums/ with TouristAttraction schema, 20 major US zoos with aquatic habitats at /zoos-with-aquatics/, and 30 US trout hatcheries open to the public at /trout-hatcheries/.
