Etymology: Pseudotropheus: Greek, pseudes = false + Greek, tropaion = defeat, a memorial of a fighting war, trophy; because of their specialized teeth were such an obvious feeding adaptation (Ref. 45335).
Eponymy: David Livingstone (1813–1873) was a Scottish doctor and missionary, and undoubtedly the most famous African explorer of all time. [...] (Ref. 128868), visit book page.

Épines dorsales (Total) : 17 - 19; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 3; Rayons mous anaux: 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).
Body shape (shape guide): fusiform / normal.
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).
