Seriously Fish

Seriously Fish bridges the gap between a global taxonomy database and the questions asked before a freshwater purchase. Its species profiles can be filtered by tank size, water parameters, difficulty and origin, or browsed through order, family and genus. The current site reports more than 1,800 species, thousands of photographs and a glossary of roughly 1,700 scientific and fishkeeping terms. Geographic browsing and articles on taxonomy, conservation and care help place a captive animal in its natural and scientific context rather than reducing it to pH and length.

Coverage is extensive but not universal, and a profile's numerical range should not become an invitation to keep an animal permanently at an extreme. Collection locality, social structure, aquarium footprint and available shelter can matter more than a single headline value. Some taxonomic conclusions also change after publication. Use the database to learn names, behavior and broad husbandry needs, then cross-check unusual or high-consequence choices with primary literature, experienced specialist groups and the source of the actual stock.
