Often in large schools (Ref. 5227) over coral and rocky reefs (Ref. 9286). Feed on algae, gastropods, and small crustaceans (Ref. 9286). Pick parasites from larger fishes like Paranthias colonus and Mulloides dentatus (Ref. 28023). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
在珊瑚礁与岩礁之上常形成大群鱼群 (参考文献 5227) 。 (参考文献 9286) 吃藻类, 腹足动物 , 与小型甲壳动物.(参考文献 9286) 剔啄来自较大的鱼的寄生虫例如东太平洋副花鮨〔Paranthias colonus〕 与 Mulloides dentatus.(参考文献 28023) 卵生的.(参考文献 205) 形式在繁殖的时候配对。 (参考文献 205)
