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).
在珊瑚礁與岩礁之上常形成大群魚群 (參考文獻 5227) 。 (參考文獻 9286) 吃藻類，腹足動物與小型甲殼動物。 (參考文獻 9286) 剔啄來自較大的魚的寄生蟲例如東太平洋副花鮨〔Paranthias colonus〕 與 Mulloides dentatus.(參考文獻 28023)
