Around the 13th century, during the reign of the Nan Song Dynasty, goldfish became common pets throughout China. Eventhough the goldfish is native to asia, it is also found in many other locations throughout the world. Goldfish were first introduced to North America around the late 1900s.

Wild goldfish live in lakes, ponds, streams and rivers. Over the centuries , many goldfish varieties have been developed with strange and unique shapes.
