Companion Animals

Freshwater Fish Welfare in Aquariums

Aquarium fish are among the most poorly catered for pets in terms of welfare understanding and provision.

Key Facts

The global ornamental fish trade involves approximately 1 billion fish annually
Most commonly kept freshwater fish including goldfish have been misrepresented as easy, low-need pets
Goldfish need ponds or large filtered tanks; bowls cause chronic stress and shortened lifespan
Betta fish marketed in tiny cups at pet shops suffer from stress and cannot display natural behaviour
Water quality, temperature, and appropriate social grouping all significantly affect fish welfare

Welfare Considerations

Freshwater aquarium fish are frequently subjected to conditions that cause chronic welfare impairment. Inadequate tank size, poor water quality, inappropriate social grouping, and incompatible species combinations cause stress, injury, and premature death. Fish welfare deserves the same serious consideration as any other companion animal.

What You Can Do

Research species-specific needs thoroughly before acquiring any fish
Never keep goldfish in bowls; provide appropriately sized filtered aquariums or ponds
Match tank size and conditions to the species kept, not to the size of the fish at purchase
Adopt fish from rescue organisations rather than buying from pet shops where possible
Advocate for improved fish welfare standards in the ornamental fish trade
