Found in coastal waters, over sandy or muddy areas of lagoons, reef flats and tide pools; enters harbors (Ref. 9812). Schooling species, swim at various depths along reefs, to about 20 meters but usually much shallower. Feed on detritus containing algae and microscopic animals, by scooping up the upper layer of sand or mud and filtering through the gills (Ref. 48637). Omnivorous (Ref. 6113). Form large schools before spawning, at the beginning of the ebb tide (in June), over shallow, open areas of the lagoon slope (Ref. 9812). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Spawning occurs in large aggregations after dark. Marketed fresh (Ref. 9812). Minimum depth reported taken from Ref. 30874.
