成鱼的身体深灰褐色; 稚鱼黄色; 在鳃裂的上端是一条鲜橘色的水平条纹后面, 有带紫色的黑色边缘。 头部与前半部的身体通常突然地比后半段灰白。 前面的鳃耙 24-28; 在后部的 23-27. 大的雄性成鱼 (大约 17 公分) 有更明显中凸的吻轮廓。
Inhabit seaward reefs, in areas of bare rock or mixed rubble and sand, from 9 to at least 46 m depth; juveniles inhabit protected bays and lagoons, singly or in small groups in as little as 3 m (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Adults occur singly or in schools and feed on surface film of detritus, diatoms, and fine filamentous algae covering sand and bare rock (Ref. 1602). Rarely poisonous (Ref. 4795).
在裸露岩石或混合的碎石与沙的区域中，栖息于临海礁石, 从 9 到至少 46 公尺深; 稚鱼栖息于遮蔽的内湾与舄湖, 各别地或形成小群鱼群在浅到 3 公尺中.(参考文献 1602,48637) 成鱼各别地出现或者成群而且吃表面的碎屑薄片，硅藻与细的菌丝藻覆盖沙子与裸露的岩石.(参考文献 1602) 此鱼种是很少有毒的。 (参考文献 4795)
