Usually solitary but in Lembeh often aggregates in small schools of up to 10 individuals. Mostly on reefs but also around moorings and outgrows on the sandy bottom divesites. During the day hides motionless seeking protection from any structure. It hunts during afternoons, at dusk and during night. When it hunts it hovers above the bottom, displaying its dorsal rays and streamer-like pectoral fins waiting for its prey.
