I have a pair of young clown fish and a small anenome. Only one of the two clown fish sleeps in the anenome. Is that one usually the male or the female? I can't currently tell. They're the same size really.
I have 3 pair, on 1 pair they are the same size. The other 2 pair, the smaller one seems to stay close to whatever they are hosting. In my case, 1 hosts a Rainbow Trachy, 1 hosts a bright green leather and the 3rd hosts a hammer.
