This fish lives on reefs and at depths of up to 12 m. They feed on algae, small crustaceans, small fish and invertebrate larvae. They are silvery-grey with a yellowish back and five black bars on the sides. The reproduction of this species is oviparous, with the males being in charge of creating a nest in which the females will deposit the eggs that the male will fertilise. The clutches are incredibly numerous and are cared for by the male.
