Breeding yellow coris

This species have not been bred in aquariums. In the wild, it breeds in harems where one male keeps several females. Perfect conditions and keeping them in a harem is likely required to breed them. Sexing the Yellow coris / wrasse is a bit harder than sexing other wrasses, but females are generally speaking smaller and less colorful. It is hermaphroditic and all (most) fish are born females and then develop into males if there is a shortage of males. Some fish – so called super males – are genetically determined to be males their entire lives.
