Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.3 cm SL male/unsexed; (Ref. 5684)
(total): 16 - 19;
soft rays: 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).
Found in rocky areas which may be sediment-free and shallow or sediment-rich at somewhat deeper levels. Feeds at right angles with the substrate by combing loose material from the biocover. Also feeds on plankton in the open water (Ref. 5595).
