Description

Butterfly Koi also known as Longfin Koi, or Dragon Carp are a type of ornamental fish notable for their elongated finnage. They are also sometimes referred to as Dragon Koi.

The fish are a breed of the common carp, Cyprinus Carpio which includes numerous wild carp races as well as domesticated Koi (“Nishikigoi”). Butterfly Koi originated in the mid-20th century as a result of an effort to increase the hardiness of traditional Koi. Japanese breeders interbred wild Indonesian Longfin River Carp with traditional Koi. The resulting fish had longer fins, long barbells, pompom nostrils, and were hardier than Koi.
