The global ornamental fish trade is worth over 4 billion dollars annually. The welfare implications of keeping aquarium fish are substantial and largely unrecognized by the public.
Aquarium fish welfare failures are pervasive and largely invisible. The aesthetics of fishkeeping — bright colors, interesting species, lively movement — mask the suffering of fish in inadequate conditions. Wild-caught marine fish collected with cyanide arrive with organ damage and often die within months. Fish kept in bowls too small for adequate filtration experience chronic ammonia and nitrite toxicity. Bettas kept in tiny containers without filtration or enrichment suffer from poor water quality and behavioral deprivation. The aquarium trade is built on consumption of fish whose welfare needs are not understood by most buyers — and who die rapidly, driving repeat purchases that sustain the cycle.
