背棘 (總數) : 17 - 19; 背的軟條 (總數) : 9 - 10; 臀棘: 3; 臀鰭軟條: 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那裡它在腹足動物， Lanistes nyassanus 的空貝殼中的發現藏身處. 也發現於中間的棲息地與很少超過岩石。 通常具有領域性腹足動物貝殼之上。 當發現遠離它的貝殼, 它通常是獨居性或形成小群魚群少於 5個個體。 從沙子覓食, 帶 epipelic 藻類。 (參考文獻 6256)
