大小 / 重量 / 年齡
Maturity: Lm ?  range ? - ? cm
Max length : 11.3 cm SL 雄魚/尚未辨別雌雄; (Ref. 5684)
背棘 (總數) : 16 - 19; 背的軟條 (總數) : 7 - 10; 臀棘: 3 - 4; 臀鰭軟條: 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).
頭部中等傾斜; 腦顱的嘴頂端腫大的; 顎 isognathus; 外部的列那頜部有雙尖齒。 沒有在組合的藍灰色背鰭的任何被中斷的有顏色在一個藍色的地面上有黑色的橫帶。 第一角鰓骨上的鰓耙 8-14; 第一上鰓骨上的鰓耙 1-3.
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).
