Adults are found in sandy areas of both lagoon and seaward reefs. They occur in small groups with outcrops of soft coral patches or gorgonians, usually in depths over 20 m (Ref. 48636). Feed primarily on zooplankton. Oviparous, males guard the nest (Ref. 59303). Eggs are demersal and adhere to the substrate (Ref. 205).
