Ryukin Goldfish

The Ryukin goldfish is a very beautiful fancy goldfish variety with a characteristic hump in the shoulder region. It is actually Chinese in origin. But is named ‘Ryukin‘, because it was said to have arrived in Japan through the Ryukyu islands which lies between Taiwan and Japan.

There were historical references that the existence of the Ryukin goldfish dates back in 1833. But the variety is said to have arrived in Japan in the 1770s. Early Japanese literature refers to these fish as the Onaga or the Nagasaki goldfish. In English, they are also sometimes called as the Veiltail, Fantail, Fringetail or the Japanese Ribbontail.

Currently the Ryukin goldfish is very popular in both Japan and the United States. However, read some more information about this goldfish variety below.

Characteristics
The Ryukin goldfish are similar in body shape and appearance to the Fantail goldfish. But they are easily differentiated from the Fantail by their extremely high back (which is often described as a dorsal hump). They have a pointed head and have a pronounced hump on the back behind the head. They can be either long-finned or short-finned, with either a triple or quadruple tail. Their dorsal fin is high while the caudal fin is often twice as long as the body. Their caudal fin may also have 3 or 4 lobes.
