About the species
Julidochromis marlieri, the Marlier's or checkerboard julie, is a small rock-dwelling cichlid endemic to Lake Tanganyika, instantly recognizable by the grid of dark markings stamped across its pale, elongate body. It belongs to the handful of "julies" that hug the rocky reefs of Africa's deepest lake, grazing the thin film of algae, sponges, and tiny invertebrates that coats the stone. Its most surprising trait is social rather than visual: in this species the female is the larger, more dominant partner of a bonded pair, a sex-role reversal rare among monogamous cichlids that has made the fish a favorite subject for behavioral biologists.
