Adults are found in very shallow, protected water, over coral and rocky bottoms. Young often sheltering among the branches of Pocillopora; occasionally commensal with the anemone Marcanthia cookei (Ref. 9710). Benthopelagic (Ref. 58302). Peak spawning from May to August. Age-at-maturity estimated at one year. Feed on zooplankton, benthic invertebrates, and algae (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Have been reared in captivity (Ref. 35412).
发现于很浅又遮蔽的水了, 在珊瑚与岩石底部之上。 时常被在 Pocillopora 的分支之中隐匿的幼鱼; 偶然地与卷曲异辐海葵 Marcanthia cookei 共生。 生殖高峰从五月到八月。 成熟岁数估计了一年。 吃浮游动物，底栖的无脊椎动物与藻类。 (参考文献 9710) 曾经后面在繁殖场.(参考文献 35412)

Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species, recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).中太平洋東部: 夏威夷群島與詹斯頓島。
