Live in various reef habitats, sand slopes and lagoons (Ref. 48637). Juveniles inhabit shallow, protected, turbid inshore waters while adults prefer deeper areas of protected bays and lagoons. Also in outer reef areas (Ref. 1602). Benthopelagic (Ref. 58302). Schooling species, feed on diatoms, detritus film of sand, filamentous algae, hydroids, and pieces of fish (Ref. 1602, 48637). Probably the only surgeonfish that readily takes bait (Ref. 12484).
生活在各种不同的礁石栖地，沙质斜坡与舄湖。 (参考文献 48637) 稚鱼栖息于水浅且有遮蔽又混浊的近岸水域虽然成鱼偏爱遮蔽的内湾与舄湖的较深的区域。 也在外围礁石区域中。 这群游性种吃硅藻，沙中的碎屑薄片，菌丝藻，水息虫与鱼的碎片。 (参考文献 1602,48637) 可能轻易地吃饵的唯一的刺尾鱼.(参考文献 12484)
