Kloubec Koi Farm is a breeder of Butterfly koi as well as straight fin koi. All of our Butterfly parent stock are of Japanese lineage obtained from famous Japanese koi breeders Suda, Yamasan, and others. Butterfly koi fish are produced in many varieties including Sanke, Kohaku, Yamabuki Ogon, Showa, Kumonryu, Ochiba Shigure and more. We continuously strive to produce the best butterfly koi for sale with fins that are graceful and that are in accordance with the AKCA judging standards for Longfin koi.
Butterfly Koi are known for their elongated fins. Developed in the mid-21st century as a result of Japanese koi breeders’ efforts to improve the hardiness of traditional koi, they combined wild Indonesian Longfin river carp with their traditional koi. Not only was the outcome a hardier fish, it surprisingly featured longer fins and barbels, as well as exaggerated nostrils. Their decorative pompom nostrils are called narial bouquets.
