A butterfly Koi is simply a Koi with longer and straggly finnage. They are sexed in exactly the same way as all other Koi and/or goldfish. The Koi does not reach sexual maturity until it is about 10 inches long so it can not be sexed until then. Once sexually mature the females tend to have a chubbier appearance than the males and (as with goldfish) the males develop whitish spots (Pimples) on their gill plates and pectoral fins when they come into breeding condition.
