Adults inhabit rocky boulders from depths of 2 to 5 m, common at depths less than 10 m (Ref. 6211). They live in small groups, each comprising a male and several females (Ref. 48636) on rock surfaces and under ledges and tidepools (Ref. 75031). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
在 2-5 公尺深范围中栖息于岩石的大圆石而且生活在小群鱼群，每个包含一只雄鱼与好几只雌鱼中。 (参考文献 48636) 生活在岩石表面与岩架下; 普遍于深度小于 10 公尺。
