About Fishician

What Fishician is for

Fishician helps aquarium keepers make fewer decisions from memory or guesswork. Users can plan a tank, track livestock and water tests, organize maintenance, compare possible stocking conflicts, explore educational guides, and keep their aquarium history together.

The public educational library and private application serve different purposes. Editorial guides are durable, source-linked content. Species catalog records support planning tools but are not represented as finished articles until they pass the editorial requirements. Community posts are user-generated. AI outputs can be wrong and must not be confused with verified reference content or veterinary diagnosis.

How Fishician stays free

Fishician uses affiliate referrals and may earn a commission when a user buys from a participating retailer, at no additional cost to the user. Affiliate status does not control compatibility results or care guidance. Fishician does not currently load third-party programmatic advertising scripts. See the advertising and affiliate disclosure.

Limits and responsibility

Fishician is not an aquarium retailer, veterinary practice, laboratory, or emergency service. Educational information cannot account for every animal, product formulation, source-water condition, or local law. Serious, urgent, persistent, or uncertain animal-health concerns should be reviewed by a qualified aquatic veterinarian or aquatic animal health professional.
