Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 4392)
soft rays: 11. True form has interrupted mid-lateral stripe. Female with yellow stripe from the tip of snout to just past axil, running below eye where pale silvery-blue; male with continuous mid-lateral line and dark 'ear' (Ref. 48636).
Coastal to outer reef crests. In Japan, it is found in areas of mixed sand, rock and coral (Ref. 9710). Occurs in small groups to about 20 m depth (Ref. 48636). Feeds by sorting small animals from mouthfuls of sand and detritus.
