Fantail (Metallic and Calico, English, Japanese and American)


The Fantail is generally thought to be Japanese in origin. It is a cross between the Wakin and the Ryukin. In the 1940’s the English have promoted improvements to Fantails, making them stockier. In North America, a small group of people breed these hardy specimens. In the United States these fish are commercially bred. Some of the more vigorous fish in North America are short tailed offspring of Veiltail crosses.
