Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm TL male/unsexed; (Ref. 90102); common length : 14.0 cm SL male/unsexed; (Ref. 3810)
soft rays: 7. Head scales reaching forward to between level of anterior margin of eyes and posterior nostrils. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine present beneath eye. Pelvic fins moderately long, reaching to or almost to level of anus. Color: Upper body greyish-brown, silvery-white below. A pearly-blue streak from behind eye along dorsal fin base. An oblique, brown-edged pearly-blue bar above the pectoral base. An elongate white blotch below lateral line on posterior half of body, a yellowish tinge above this blotch. Snout dusky and a black blotch on opercle.
Inhabits coastal waters around rocky-rubble and seaweed areas of coral reefs, outer slopes and lagoons. Usually in small groups but may be seen solitary (Ref. 48635, 90102). Feeds mainly on benthic crustaceans.
