Livestock care standards
- We only catalog species with established captive-care protocols.
- Tank-size minimums reflect adult size + territory needs, not juvenile size at purchase.
- Difficulty ratings are based on real reef-keeping outcomes, not seller claims.
- We flag wild-caught species that are challenging in captivity (e.g., cleaner wrasse).
⚠ Always quarantine new fish for 14–30 days in a hospital tank with copper or TTM treatment. Skipping quarantine is the #1 cause of full-tank wipe-outs from ich and velvet.
