Chagoi are solid colored brown or bronze koi with a subtle reticulated net pattern. Although they are not nearly as flashy or colorful as other types of koi, Chagoi are still a welcome addition to koi ponds. Because of their close genetic relationship with wild carp, Chagoi are some of the friendliest and most docile koi available. This makes them the easiest to train to hand feed, and other varieties of koi may follow suit when they see a Chagoi hand feeding.
