Inhabit coral-rich areas of lagoon and seaward reef (Ref. 9710). Found in pairs or aggregations (Ref. 9710). In Indonesia usually seen in pairs in coastal waters. Offshore it may form schools and in the Maldives they occur in great numbers. Found at various depths, often on shallow reef crest with some surge. Usually in mixed algae and coral habitats to about 15 m depth, but may go offshore (Ref. 48636). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
