Red and White Ryukin Goldfish Fish Profile – Care Sheet

The Ryukin Goldfish is an egg-shaped variety of goldfish. The body is short and stubby. Their extremely high back, which is often described as a dorsal hump, starts in the neck region and gives the Ryukin’s head a pointed appearance. The beautiful Ryukin Goldfish are a Japanese version of the Fantail Goldfish. They were developed from the common Fantail Goldfish. Like their Fantail counterpart, they are one of the more rounded or egg-shaped fancy goldfish. Ryukin Goldfish are recommended for the beginner, but like all the goldfish with this rounded body shape, they can be susceptible to swim bladder problems.
