Adults are benthic and benthopelagic in or over coral (Ref. 58302). They hover generally above the reef waiting for unwary prey. They feed on fishes. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Difficult to rear in aquaria because they cannot easily be induced to accept ordinary fish food (Ref. 3921).
