Goldfish are among the most commonly kept and most commonly neglected aquarium fish. Their welfare needs are systematically misunderstood, leading to preventable suffering in millions of captive individuals.
Goldfish welfare is compromised primarily by misinformation about their care requirements that is perpetuated by the pet industry and popular culture. The idea that goldfish are disposable, simple pets requiring minimal care directly causes preventable suffering for billions of individuals. Well-kept goldfish in appropriate conditions live for decades and display genuine individuality and responsiveness. A goldfish kept in a bowl is equivalent to keeping a dog in a cage too small to stand — the spatial and social deprivation is equivalent relative to species needs.
