Indo-West Pacific: Gulf of Oman to the Philippines and Australia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 2334)
Found in clear coastal slopes to outer reef lagoons on open rubble patches or rocky bottom (Ref. 48636). Occurs in groups (mostly females) on or near reefs, usually where the water is somewhat turbid and rich in plankton. Fish in the initial phase are much more abundant than the terminal males. Feeds on zooplankton at least a meter above the substrate.
