背棘 (总数) : 17 - 19; 背的软条 (总数) : 9 - 10; 臀棘: 3; 臀鳍软条: 8 - 9. Diagnosis: This species is distinguished from all other members in Pseudotropheus, except P. crabro, P. demasoni, and P. saulosi, by the presence of five or fewer vertical bars below the dorsal fin; most Pseudotropheus species either have no bars or have greater than five below the dorsal fin (Ref. 119458). It is distinguished from P. crabro, P. demasoni, and P. saulosi by a pale yellow to hyaline dorsal fin vs. dorsal fin heavily pigmented with black (Ref. 119458).
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).
主要地在沙子之上住在哪里它在腹足动物， Lanistes nyassanus 的空贝壳中的发现藏身处. 也发现于中间的栖息地与很少超过岩石。 通常具有领域性腹足动物贝壳之上。 当发现远离它的贝壳, 它通常是独居性或形成小群鱼群少于 5个个体。 从沙子觅食, 带 epipelic 藻类。 (参考文献 6256)
