Wyoming White is the rarest mainstream designer clownfish strain. Pure white body with no visible bars - a striking inverse of the standard ocellaris. Captive-bred only (the mutation is recessive + slow to scale). $250-600 per fish makes it one of the most expensive captive-bred marine fish.
Wyoming White is a recessive line bred from melanistic ocellaris carrying the white-body gene. Multiple breeders have stable lines - Sustainable Aquatics in Tennessee + Proaquatix in Florida + ORA are the major US captive-breeders.
The mutation is slow to produce - juveniles take 6-12 months to develop full white body. Many fry from Wyoming White x Wyoming White pairings still develop standard ocellaris coloration (recessive recovery).
Juvenile (1-2 inch): $250-400.
Adult (3-4 inch): $400-600.
Bonded pair: $700-1,200.
Among the most expensive captive-bred marine fish in the hobby. Premium reflects breeding difficulty + collector demand.
Standard ocellaris husbandry: 20+ gallon tank, salinity 1.023-1.025, temperature 74-80F, peaceful tank mates. Wyoming Whites are MORE peaceful than standard ocellaris (selection effect from captive-bred lineage). They host most clownfish-compatible anemones.
Fast Aquatics aggregates Wyoming White listings from charter breeders. Verify the source - established breeders carry documented Wyoming White lineage. Single-fish sales are common; bonded pairs are typically pre-paired by the breeder.

Browse Wyoming White Clownfish listings →Yes - it's a captive-bred color morph of Amphiprion ocellaris. Wyoming Whites can pair with standard ocellaris but offspring will mostly be standard pattern (the white mutation is recessive).
Slow-to-scale captive breeding + collector demand. Each fish takes 12-18 months from spawn to sale-ready size. Recessive mutation means many fry from Wyoming White parents revert to standard pattern - the per-spawn yield of saleable Wyoming Whites is low.

Answers to the questions experienced keepers ask after the basic care guide.
Drip acclimation over 60 to 90 minutes is the safest approach for Wyoming White Clownfish Buy Guide - Fast Aquatics Guide. Match temperature first (15 minute float), then drip 2 to 3 drops per second from the display sump until the bag volume has tripled. Test salinity (or freshwater hardness) at the end - if it is within 0.001 SG (or 2 dGH) of the display, transfer the specimen with a net rather than pouring shipping water in.
Aim for biological + mechanical + chemical staging. Canister or sump-driven filtration sized for 5x to 8x display turnover per hour, mechanical floss replaced weekly, and carbon or GAC swapped every 4 to 6 weeks. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide responds well to stable nitrate (under 20 ppm) more than to any specific filter brand - stability beats peak performance.
For saltwater specimens, yes - a properly-sized skimmer rated for 1.5x to 2x display volume keeps dissolved organics low and reduces nuisance-algae triggers. Freshwater specimens do not need skimmers; a well-stocked plant grow-out + canister with chemical media achieves the same end. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide kept without adequate organic export tends to show stress within 90 days.
Compatibility with planted tanks depends on the species behavior + water chemistry overlap. Plant-safe specimens leave foliage alone; some pick at soft-tissue plants like vallisneria or anubias. Check the species page profile + the planted-tank compatibility note before stocking Wyoming White Clownfish Buy Guide - Fast Aquatics Guide in a high-tech CO2-injected setup with valuable cultivars.
For freshwater specimens with no plant requirements, a basic LED at 30 to 50 PAR at substrate is sufficient and reduces algae. For saltwater + reef specimens, target 100 to 250 PAR depending on photo-tolerance, with a sunrise/sunset ramp + a 8 to 10 hour photoperiod. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide tolerates a wider lighting band than most keepers expect; consistency matters more than peak intensity.
Most aquarium species evolved in moderate flow with localized turbulence rather than uniform high flow. Aim for 20x to 40x display turnover for reef specimens, 4x to 6x for community freshwater. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide shows stress fins (clamped, frayed) when flow is mismatched - dial back if you see this within 14 days of introduction.
Sustained drift above +/- 2 F from target is the threshold most keepers miss. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide tolerates day-night swings of 1 to 2 F without issue but a 4 F shift over 2 hours triggers ich + bacterial bloom risk. Use a controller-driven heater (not the built-in dial) and a backup thermometer at the opposite end of the tank.
For freshwater fish: ich, columnaris, and fin rot are the top three; quarantine + UV sterilizer prevents the majority. For marine fish: ich (Cryptocaryon), velvet (Amyloodinium), and bacterial infections; tank-transfer method or copper QT during the 30-day acclimation cycle prevents nearly all outbreaks. For inverts + corals: tissue necrosis, parasitic isopods, and protozoan blooms.
Captive breeding success varies enormously by species - some breed readily in community tanks (livebearers, cherry shrimp, clownfish) while others have never been captive-bred (most reef fish + most marine inverts). Check the species-specific care guide for the breeding-method note + larval-rearing protocol. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide kept in pairs or small groups often spawns even without intent if conditions are right.
Avoid same-species rivals (especially male-male pairings for territorial species), known fin-nippers (tiger barbs, certain pufferfish), and anything that out-competes for food or out-grows the tank. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide also struggles with hyper-aggressive cichlids in freshwater and damselfish in saltwater - both will hold territory at the expense of every other tankmate.
Most ornamental specimens accept cleaner shrimp + cleaner gobies; cleaner wrasses (Labroides) often die in captivity and are not recommended. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide kept with cleaner pairs typically benefits from parasite control + stress reduction, but verify the cleaner does not get eaten by checking the species size + temperament chart.
Captive lifespan tracks closely to wild lifespan when water chemistry, diet, and tankmate stress are managed. Most aquarium fish live 5 to 12 years; long-lived species (large cichlids, pufferfish, some tangs) reach 15+ years. Wyoming White Clownfish Buy Guide - Fast Aquatics Guide kept in a stable, properly-sized system should live within 80% to 100% of the species lifespan ceiling - early death usually traces back to chronic-stress causes (parameters, tankmates, diet) rather than disease.
