The funniest part of it all is that all clownfish are born males, with the leading male gaining weight and turning into a female when the original female dies. The largest fish in the group is the female while the male is slightly smaller than her. In maintaining his dominance, the clownfish ensures that the best food opportunities are for him. When mating, the couples pair off and breed together with females sometimes laying a thousand eggs and the male going along to fertilize and guard them until it’s time for hatching. In a bizarre twist, if an egg is of inferior quality or damaged the male will typically eat the egg.
