Fantail (goldfish)

The Fantail is a goldfish that possesses an egg-shaped body, a high dorsal fin, a long quadruple caudal fin, and no shoulder hump. It is similar to the Ryukin, and is relatively common in western countries. The Fantail Goldfish is the base for many fancy goldfish species.

Description
The Fantail goldfish may have either metallic or nacreous scales and normal or telescope eyes. Telescope eyes do not develop until the fish is 6 months old. Its fins are less developed than the Ryukin. It supports double anal and tail fins. The anal and caudal fins are well divided into two matching halves. Although generally considered a hardy goldfish, Fantails can be sensitive to prolonged exposure to low water temperatures. Keeping Fantails in an aquarium requires an ideal temperature of 73 to 74°F (23°C)

Breeding
Good-quality Fantails are produced by rigorous fry selection. Fantails can be very easy to breed.
