How do i tell the differance between boy and girl Koi? -Pickles Paulson

It is nigh impossible to tell the difference when they are young and small, you have to wait for Koi to get older before you can tell the difference. You can usually tell when they are at least 2 years old. Female Koi will take on a blimp shape (they get full of eggs) and male Koi will look like a cigar. Share: Del.icio.us Digg Reddit
