生物學特性     字彙 (例如 epibenthic)

Occur in small groups in reef flats, clear lagoon and seaward reefs (Ref. 48636). Benthopelagic (Ref. 58302). Feed on soft and hard corals, also on polychaetes, small crustaceans, and filamentous algae. In Indonesia, usually seen at moderate depths, usually swimming in small groups. Adults are mainly in depth 20-60 m (Ref. 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

在礁石平臺,清澈的潟湖與臨海礁石中出現在小群魚群。 捕食軟的與硬珊瑚,也吃多毛類動物,小型甲殼動物與菌絲藻。 在印尼, 通常見到在深度中等之處, 通常在小群魚群中游泳。 成魚主要在深度 20-60 公尺。 (參考文獻 48636) 卵生的 (參考文獻 205) ,一夫一妻的.(參考文獻 52884)
