The Maurician clown fish is a hermaphrodite fish. It is a successive hermaphroditism. The fish are initially males then they become female. They are monogamous. They are very territorial fish, they do not accept other rival fish. Once the female dies, the (dominant) reproductive male turns into a female. The bigger immature male becomes the male reproductive male. The eggs her attached to a piece of coral near the anemone. The male fertilizes the eggs one after the other. This phase can last an hour. Then the male will keep the eggs, clean them regularly, heal them and he protects them from any predators until they hatch. It oxygenates the water by beating the pectorals or expelling water through the mouth on the eggs. During egg incubation, which lasts eight days, their color changes from bright orange to dark brown before becoming silver on the day before hatching. The eyes of the larvae are then clearly visible. The eggs measure about 3 mm. The hatching takes place shortly after sunset, according to the phases of the moon and the temperature of the water. After this hatching at the foot of the protective anemone, planktonic larvae, 4 to 5 mm in size, float in the stream for about 15 days until the fry are large enough to reach a new anemone And start growing.
