Goldfish
Ornamental goldfish are descended from ancient carp, and have been selectively bred for centuries in Asia and Europe to obtain species with specific genetic traits. Fish are bred for certain color combinations as well as for certain scale texture, body shape, and finnage. Many of these fish are slow moving, and should not be housed with koi or standard goldfish because these other fish are much faster and more food aggressive. Ornamental goldfish make a beautiful addition to small or large ponds.
