Koi Types
Soragoi
Soragoi are a solid grey Koi. They make a great addition
to any Koi collection. When buying a Soragoi, look
for any old scars or
any bad scales. The Soragoi in the picture below is actually a Gin Rin
Soragoi. It's scales look strong enough to turn any blade.

Soragoi
Soragoi, along with Chagoi, are used to create Ochiba Shigure. By
combining these two single colored Koi, the Japanese breeders have made
a two
colored Koi with a pattern.
