Goldfish (Carassius auratus) are small ornamental freshwater fish that are commonly kept as pets. Goldfish were one of the earliest breed of fish to be domesticated and are still one of the most commonly kept fish in aquariums and outdoor water gardens.
Goldfish were originally domesticated from the Prussian carp (Carassius gibelio), a dark greyish brown carp native to Asia.[1] It was first bred for color in China over 1,000 years ago. Due to selective breeding, goldfish have been developed into many distinct breeds and are now found in various colors, color patterns, forms and sizes far different from those of the original domesticated carp.[2]
