Anmärkningar	Occurs in shallow coral reefs, as well as deeper offshore waters (Ref. 3724). A nocturnal species, hiding in deep crevices or under coral ledges during the day; at night it usually moves over sand and grass beds, taking mainly crabs and other small crustaceans (Ref. 3634). Mobile invertebrate feeder (Ref. 126840). Carnivore (Ref. 33499, 40102, 57616). Also cleaned by Elacatinus figaro observed off the coast of São Paulo, southeastern Brazil (Ref. 40102) and by Pomacanthus paru observed at the reefs of the Abrolhos Archipelago, off eastern Brazil (Ref. 40094).
