Biologie     Verklarende woordenlijst (b.v. epibenthic)

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).
