大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 11.3 cm SL 雄鱼/尚未辨别雌雄; (Ref. 5684)
背棘 (总数) : 16 - 19; 背的软条 (总数) : 7 - 10; 臀棘: 3 - 4; 臀鳍软条: 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).
头部中等倾斜; 脑颅的嘴顶端肿大的; 颚 isognathus; 外部的列那颌部有双尖齿。 没有在组合的蓝灰色背鳍的任何被中断的有颜色在一个蓝色的地面上有黑色的横带。 第一角鳃骨上的鳃耙 8-14; 第一上鳃骨上的鳃耙 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).
