Found on hard substrates of shallow lagoon and seaward reefs from the lower surge zone to a depth of more than 15 m (Ref. 27825). Benthopelagic (Ref. 58302). Feed on filamentous algae. Form spawning aggregations (Ref. 27825, 48637). Adults usually in small groups, but form large schools in some oceanic locations. Juveniles are often seen in mixed species aggregations (Ref. 48637). Species at the bottom of the 'pecking order' among surgeon fishes, and as a result employs the strategy of feeding in large schools that overwhelm the territorial defenses of other herbivores (Ref. 1602). Caught with nets (Ref. 30573). Can be eaten both raw and cooked (Ref. 7364). Maximum depth reported at 25m (Ref. 027115)
棲息於潟湖淺灘與臨海礁石的堅硬底部從低浪花區到深度超過 15 公尺.。 吃絲狀藻類。 形成產卵群集。 (參考文獻 27825,48637) 成魚通常在小群魚群, 但是在一些大洋性的地點中形成大群魚群。 稚魚時常被在混合的種群集中見到。 (參考文獻 48637) 在外科醫生魚之中的 ' 啄醫生' 的底部的一個種, 而且作為一個結果大群魚群產生覓食策略以征服其他草食動物的具有領域性防衛.(參考文獻 1602) 用網捕獲.。 (參考文獻 30573) 能被吃生的而且煮.(參考文獻 7364) 最大的深度在 25 公尺報告 (參考文獻 027115)
