Carassius auratus
A ranchu-bodied goldfish in calico dress whose caudal fin grows long. The name covers the long-tailed fish that appear while breeding the Edo nishiki, and it is not yet a stabilised variety.
Kyo nishiki is the name given to the long-tailed fish that appear while breeding the Edo nishiki. The Edo nishiki is a calico ranchu-type created in the Showa era by crossing the ranchu with the azuma nishiki; it has been refined since but is still not a stabilised variety. That breeding sometimes throws fish whose caudal fin grows long, and these are called kyo nishiki. The result is the round, dorsal-less ranchu body carrying calico mottling in red, black and white with the pale blue of mosaic transparent scales, combined with an extended tail. Because it is not a fixed line, fish sold under the name vary considerably in tail length and in how the pattern falls.

It can be viewed from above or from the side; light close to daylight best shows the calico and its pale blue. Strong lighting is not required.
With no dorsal fin it is not a strong swimmer, so keep the flow gentle. Avoid sharp ornaments and heavy aeration that would damage the long tail.
Combine it with other ranchu-type fish such as the ranchu or Edo nishiki. Wakin types and comets swim far too fast for it.
As an unfixed line, tail length and patterning vary widely between individuals, and the fish will not necessarily keep the look it had when acquired.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
