Anubias

What is Anubias?

Anubias is a genus of aquarium species commonly kept in home aquariums. The genus includes multiple species, each with overlapping care requirements but distinct color, growth pattern, or behavior. Aquarists choose Anubias for its combination of visual appeal, wide availability, and well-documented husbandry - unlike fringe species that require specialist care, Anubias sits in the sweet spot of mainstream aquarium keeping.

Wild populations of Anubias originate from tropical aquarium environment. The species in this genus have been kept in aquariums for decades, and most are now available as captive-bred or aquacultured specimens. Captive-bred Anubias ship healthier than wild-caught and acclimate to closed-system parameters within 7-14 days, vs. the 30-60 day acclimation typical of wild imports.

Anubias care - tank size, light, flow, parameters

Anubias is rated intermediate care difficulty across the genus, though specific species can vary. The dominant care requirements are:

• Lighting: standard
• Flow: moderate
• Diet: varied diet
• Common species: multiple species
• Color morphs available: multiple natural color morphs

For reef tanks (where most Anubias belong if it is coral or marine), maintain stable parameters: alkalinity 8-9 dKH, calcium 420-450 ppm, magnesium 1300-1400 ppm, nitrate 5-10 ppm, phosphate 0.03-0.05 ppm. Daily alkalinity swing should not exceed 0.5 dKH/24h. For freshwater Anubias, target stable temperature (within 2°F daily swing), pH appropriate to native habitat, and weekly 25-30% water changes.

How to choose a healthy Anubias specimen

Visual inspection at point of purchase prevents 70%+ of post-purchase losses. For Anubias, evaluate:

• Coloration: matches reference photos for the species. Faded or pale specimens are stressed.
• Tissue/fin condition: no recession, fraying, or discoloration. Fully extended polyps (coral) or alert posture (fish).
• Feeding response: ask the seller to feed - healthy Anubias should eat or at least respond.
• Sourcing transparency: ask if captive-bred, aquacultured, or wild-caught. Reputable sellers will tell you.
• Photos before paying: request a 30-second video of the actual specimen. Walk away from sellers who refuse.

Reputable Fast Aquatics vendors disclose collection origin on every Anubias listing. Browse current availability with carrier-tracked Buyer Protection on every order, and a 4-hour DOA guarantee starting at carrier-reported delivery.

Acclimating Anubias to a new tank

The first 60-90 minutes after delivery determine whether Anubias thrives or limps for weeks. Drip acclimation is the safest universal protocol:

1. Float the sealed shipping bag in the display or quarantine tank for 15 minutes to equalize temperature within ±1°F.
2. Open the bag and gently transfer Anubias with shipping water into a clean container at the side of the tank.
3. Run air-line tubing from the display, knot or use a drip valve to slow flow to 2-3 drops per second.
4. Drip until the original shipping water volume has tripled (saltwater) or doubled (freshwater). Takes 60-90 minutes.
5. Verify acclimation water salinity (saltwater) or hardness (freshwater) matches display before transfer.
6. Net the specimen into the display - never pour shipping water into the tank.
7. Lights low or off for the first 4-8 hours. No feeding for 24 hours.

Anubias tankmates and compatibility

Most Anubias species are compatible with peaceful community tankmates that share their water-chemistry needs and adult-size range. The general compatibility rules:

• Match adult size, not juvenile size - a 1" juvenile becomes a 4-12" adult depending on species.
• Match temperament - peaceful with peaceful, semi-aggressive with semi-aggressive.
• Match water-chemistry needs - reef SPS coral and FOWLR fish-eating predators are not compatible.
• Match parameter band - some Anubias need stable narrow ranges; others tolerate swings.

Common Anubias diseases and treatment

Most Anubias diseases come from skipped quarantine, parameter swings, or stress. The most common conditions to watch for:

• Marine ich (Cryptocaryon irritans) - white salt-grain spots. Treatment guide.
• Marine velvet (Amyloodinium) - fine gold dust, rapid breathing. Treatment guide.
• Brown jelly (LPS coral) - brown gelatinous mucus. Treatment guide.
• RTN/STN (SPS coral) - tissue recession from parameter swings.
• Fin rot / columnaris (freshwater) - white patches, ragged fins. Treatment guide.

Quarantine all new Anubias for 21-30 days minimum (saltwater) or 14-21 days (freshwater) in a separate tank with prophylactic treatment. The single highest-impact husbandry practice for any aquarist.
