Lives mainly over sand where it finds refuge in the empty shells of the gastropod, Lanistes nyassanus. Also found in intermediate habitats and rarely over rocks. Usually territorial over gastropod shells. When found away from its shell, it is usually solitary or in small groups of less than 5 individuals. Feeds from sand, taking epipelic algae (Ref. 6256).
