Short description

Dorsal spines (total): 12; Dorsal soft rays (total): 11 - 13; Anal spines: 2; Anal soft rays: 11 - 13. Color in life white with 3 black bars; a large brown spot on dorsal part of snout and interorbital; lips dusky or white; caudal fin pale; pelvic fins black; pectorals transparent. Margins of preorbital, suborbital, and preoperculum finely serrated.

Territorial, inhabit shallow lagoon and subtidal reef flats. Form large aggregations above staghorn Acropora thickets or in smaller groups above isolated coral heads. Feed on zooplankton, benthic invertebrates, and algae. Males invite females to spawn in their nests; protecting the eggs until they hatch and becoming very aggressive against other fish. Eggs hatch after 3-5 days; pelagic larvae feeds on plankton (Ref. 5503). Used in behavioral study. Have been reared in captivity (Ref. 35412).
