Do you have koi fish in blue?

A photographer named Dan Savage recently photographed an extremely rare blue koi fish in the carp pond in Maruga City, Fukui Prefecture.

Koi fish is an ornamental fish, which is said to have originated in China and was later introduced to Japan. Common colors in koi fish are red, white, gold and black, but blue carp is very rare. This fish has some mottled red scales on its back, which seems to have undergone a process of discoloration. -First Hotan Jade Network
