Goldfish

The goldfish was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish.

A relatively small member of the carp family , the goldfish is a domesticated version of a dark-gray/olive/brown carp native to east Asia that was introduced to Europe in the late 17th century.

The mutation that gave rise to the goldfish is also known from other cyprinid species, such as common carp and tench.

Goldfish may grow to a maximum length of 23 inches (59 cm) and a maximum weight of 9.9 pounds (4.5 kg), although this is rare; most individual goldfish grow to under half this size.
