Habitat and Ecology:
Inhabits sandy and rubble areas among coral reefs, including semi-exposed reef flats, lagoons and seaward reefs subject to mild surge (depth 3-25 m, usually down to 14 m).
Juveniles are found over shallow rubble amongst large coral heads or protected open patches on reef crests often mimicing leaves and debris being swept back and forth
by the swell. Adults are territorial and often occur in pairs over rubble areas, typically moving rubble or debris to reveal prey items. Feed on molluscs, sea urchins,
brittle stars, polychaetes, and crabs. Oviparous, distinct pairing during breeding.
This species is not protected or subject to fishery regulations. It is caught occasionally in nets, but is an uncommon component of the catch.
