Chagoi are a non-metallic brown colored Koi. When buying a Chagoi, look for one with even color. Check the fish over for any old scars or bad scales, for these will take away from the look of the Koi. Old scars will appear as dark areas.
Chagoi have the terrible habit of growing very large. It is not uncommon to see one that is 36 inches swimming around a pond in Japan.
