Characterized by pale grey body color, grading to white ventrally; presence of five, blue-edged bars extending ventrally to middle of side, each bar containing reddish brown to black blotch at bottom; blue bands; spots on head; pectoral fin base with a pair of pink stripes; dorsal fin with narrow pink bands and blue to reddish spots on second dorsal and caudal fins; without dorsal filamentous spines; rhomboid caudal fin, longer than head; length of caudal fin 2.7 in SL; longitudinal scale series 80-121; ctenoid body scales , becoming cycloid anteriorly below first or second dorsal spine; head or midline of nape without scales; side of nape with scales extending forward to above middle of operculum; usually scaled pectoral fin base in adult; partly or fully scaled prepelvic area of adult; depth of body 6.0-6.7 in SL (Ref. 90102).
Occurs in areas of fine sand and shallow lagoon reefs at depths less than 3 m, rarely at depths greater than 6 m. Adults usually in pairs, constructing burrows under rubble. Monogamous (Ref. 52884, 48637). Feeds on small invertebrates (e.g. copepods, amphipods, ostracods, nematodes, and foraminiferans) by sifting mouthfuls of sand.
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
After spawning, a paired female constructs a mound on the burrow made up of dead coral fragments while the male watches over the eggs in the burrow (Ref. 85149). The mound promotes water-exchange in the burrow which helps the male in tending the eggs (Ref. 85149). The amount of female parental investment is displayed by the height of the constructed mound (Ref. 85149). Consequently, larger females build higher mounds which affects male mating preference (Ref. 85149). Monogamous mating is observed as both obligate and social (Ref. 52884).
