Goldfish
Carassius auratus
The goldfish is native to China and was domesticated as an ornamental fish. It is a coldwater fish: it does well in an unheated aquarium. It eats plankton, small invertebrates, plants and detritus. Its eggs are adhesive and stick to submerged vegetation. It lives many years in captivity, and small round bowls harm its health.
