More Info


Ashmore and Lihou reefs in the Coral Sea, and the Great Barrier Reef from Cape York to One Tree Island, Queensland. Elsewhere, the species is widespread in the tropical, Indo-west-central Pacific.

Usually occurs in small groups in caves and crevices on steep outer reef drop-offs. 


Dorsal spines (total): 7; Dorsal soft rays (total): 7-8; Anal spines: 1; Anal soft rays: 7 - 8. This species is distinguished by the following characters: a bony interorbital 82-100% pupil diameter; usually 11 ctenoid scales in predorsal midline; second dorsal spine may reach to the base of the third dorsal fin ray (in mature males) or anterior to this point; usually five free neuromasts (sensory papillae) in row r on the top of the snout, pectoral-fin rays usually 14-15 with 1-4 branched rays in about half the individuals; an unbranched fifth pelvic-fin ray that is 47-64% the length of the fourth ray. 


Freshly collected specimens: a red to yellow background colour, a pale stripe along the mid-lateral body that continues forward over the top of the pupil ending posteriorly at a pale bar across the peduncle in front of the dark caudal blotch; a pale stripe below the eye bordered dorsally by a narrow red stripe (both light stripes blue in life).


Feeds on zooplankton in the water column.
