Kawarigoi Koi (kah-wah-rē mō-nō)
Non-Metallic Koi not in any other variety
Koi that are not included in any of the other classes are grouped as Kawarimono. They are appreciated above all by their originality or unconventionality. They are mostly non-metallic varieties with the exception of Kumonryu and Kikokuryu types. Most all can be discovered with Doitsu scales and frequently with Gin Rin scales. These are rare varieties, although most are produced at Kloubec Koi Farm.
A list of members in the Kawarigoi category is very long, here are some of the favorites: Karausugoi, Kigoi, Akame Kigoi, Chagoi, Soragoi, Midorigoi, Benigoi, Ochiba Shigure, Aka Matsuba, Kumonryu, Beni Kumonryu, Kikokuryu, Beni Kikokuryu, and Matsukawabake.
