Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 2272)
Inhabits upper portions of outer reef slopes (Ref. 1602). Benthopelagic (Ref. 58302). Hovers above the bottom, facing the current to feed on zooplankton, copepods, and crustacean larvae. Several individuals may share the same hole (especially juveniles). Has a habit of flicking its pennant-like first dorsal fin back and forth (Ref. 1602, 48637). Minimum depth reported from Ref. 9360. Monogamous (Ref. 52884).
