Inhabits exposed rocky areas and coral reefs. Often near elkhorn and staghorn corals (Ref. 9710). Commonly found in schools. Juveniles are encountered in Thalassia beds (Ref. 9626). Adults are observed in coral reefs during the day but enters open waters at night to feed on mainly on plankton (Ref. 9626), but also on small crustaceans and mollusks. Marketed fresh (Ref. 3798).
栖息于裸露的岩石区与珊瑚礁。 时常在 elkhorn 与鹿角珊瑚的附近.(参考文献 9710) 普遍地成群出现。 稚鱼在泰来草床被见到。 (参考文献 9626) 成鱼在珊瑚礁被观察在白天期间但是进入开放的水域在晚上觅食主要吃浮游生物 (参考文献 9626), 也捕食小型甲壳动物与软件动物。 在市场上销售生鲜地了。 (参考文献 3798)
