History Of The Goldfish
The goldfish (Carassius auratus) is a freshwater fish in the genus Carassius, belonging to the family Cyprinidae and is endemic to China. They were first domesticated in China from Crucian Carp during the Tang Dynasty, more than 1000 years ago. Although they are still considered members of the carp family, it is believed that they were called goldfish after a color mutation appeared, resulting in yellow-orange scales, and selective breeding of these “gold” carp varieties began. They were then kept as pets and made their way to Japan in the 16th century. They were first imported to the United States from Japan in 1878.
