Body Structure

What is the difference between the body structure of male and female Koi carp fishes? -Geetha

Male Koi fish will have a body that is long and thin, like a cigar.  Female Koi will take on a blimp shape, since they are full of eggs.  Female Koi are usually larger than males because the many males will gang up on one female during breeding season.  You don't want the males to damage the females, so they need to be smaller.
