Description
Ryukin Short Tail: A Distinctive Fancy Goldfish with Compact Elegance
The Ryukin Short Tail is a refined variety of the Ryukin goldfish, bred for its rounded body, deep arched back, and compact tail structure. Originating from Japan, this ornamental fish is prized for its aesthetic balance, graceful movement, and hardiness. Unlike long-tailed counterparts, the short tail offers better manoeuvrability, making it a suitable choice for aquarists seeking a goldfish that thrives in smaller environments without sacrificing visual appeal.
