What Is A Mukashi Ogon Koi?

The Mukashi Ogon, pronounced MOO-kash-EE oh-GOHN, is a type of koi that looks brown or bronze. This koi has a solid brown colour all over its body. Its metallic shine makes it look bronzed. People often compare Mukashi Ogon koi to metallic Chagoi, which are also single-coloured brown koi. Some call them Penny Koi or Bronze Koi because of their unique colour.
