📖 Overview

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