The Butterfly Tail Goldfish is one of the most unique of the fancy goldfish. Known of course for the tail that resembles an actual butterfly.
While the fish is at rest, the tail will fan out into the butterfly shape. Though these are gaining popularity as a side viewed fish, they are best viewed from above to get the full effect of this beautifully created tail.
The dorsal of this breed should stand straight up. The eyes of the butterfly tail goldfish will vary from bubble-eyed to flat.
The Butterfly Tail goldfish originated in China, but was brought to Japan in the early 1980’s where it was further developed.
