Originating from the Prussian Carp, the Common Goldfish most likely emerged through a form of favoritism. As fish were once kept in captivity for food, fish-keepers may have learned to recognize individuals and then become attached to their charges, and it is likely that an occasional genetic sport, or non-standard colored fish, would appear and draw greater attention. Such fish would be segregated and kept for their appearance rather than their meat, and so the Common Goldfish slowly emerged.
Physical Description
Traditionally, the body color of the Goldfish is metallic red-orange with matching fins. Young fish may be greenish bronze, changing to adult coloration after about one year. Dorsal and anal fins are relatively long based, and the caudal fin is forked and stiffly held. The lateral line is visible. Females usually appear plumper when they are viewed from above. At spawning time the male develops small white spots (tubercles) on the gill covers and head.
