Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 9710)

Adults inhabit lagoon and seaward reefs. Abundant, in large aggregations over reef tops and upper edges of slopes (Ref. 9710). Usually seen solitary in reefs, staying close to the substrate in depths of about 10 m (Ref. 48636). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
