Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 16 - 19; Raios dorsais moles (total) : 7 - 10; Espinhos anais: 3 - 4; Raios anais moles: 6 - 9. Diagnosis: The moderately sloped head, swollen rostral tip of the neurocranium, isognathous jaws, and the presence of bicuspid teeth in the outer rows of the jaws place this species in Maylandia (Ref. 27596). The absence of any interrupted pigment in the pale blue dorsal fin in combination with black bars on a blue ground colour distinguish this species from all other members of the genus (Ref. 27596).
Body shape (shape guide): fusiform / normal.
Adults are found in rocky areas which may be sediment-free and shallow or sediment-rich at somewhat deeper levels. They feed at right angles with the substrate by combing loose material from the biocover. Also feed on plankton in the open water (Ref. 5595).
