Common pet fish

This photo by Renate Volz shows another pet’s fascination with goldfish. Goldfish are one of the most commonly kept aquarium and water garden fish. They belong to the carp family and are cold water fish. Though hardy fish, goldfish often don’t live as long as they should due to too small of an environment.

Goldfish and other pet fish should not be “petted” as this can damage or remove the protective slime coat on their skin.
