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.
