Ecology of Acanthurus xanthopterus
 
Main Ref. Randall, J.E., 1956
Remarks Commonly occurs in protected deeper waters of bays & lagoons. Lives in various reef habitats, sand slopes (Ref. 48637). Juveniles inhabit shallow, protected, turbid inshore waters while adults prefer deeper areas of protected bays and lagoons, and outer reef areas. This schooling species feeds on diatoms, detritus film of sand, filamentous algae, hydroids, pieces of fish (Ref. 1602, 48637) and fleshy macroalgae (Ref. 5543). Probably the only surgeonfish that readily takes bait (Ref. 12484). Also Ref. 58534.
