Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 17 - 19; Μαλακές ραχιαίες ακτίνες (συνολικά) : 9 - 10; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 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).
