Max length : 3.5 cm SL male/unsexed; (Ref. 48637)
soft rays: 8 - 10. Characterized by translucent with broad red to brown, internal midlateral stripe from head to caudal fin base; 3-5 white to yellowish spots posteroventrally above base of anal fin; caudal fin base with presence of diagnostic black hour-glass shaped mark; all pectoral rays unbranched; longitudinal scale series 22-24; ctenoid scales, none on head, nape and base of pectoral fin; separated pelvic fins, thin membrane joining bases; fourth pelvic ray with 4-9 branches; depth of body 5.0-5.6 in SL (Ref. 90102).
Inhabits clear coastal reefs and protected outer reef coral habitats. Usually at moderate depths of 10 meters or more, swimming near sponges or corals when feeding on plankton (Ref. 48637). Hovers in groups above branching corals of protected reefs (Ref. 9710).
