More on author: Gilbert.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 20 - 119 m (Ref. 7247). Tropical; 30°N - 30°S
Indo-West Pacific: scattered localities, including the Hawaiian Islands, Marquesas, Ryukyu Islands, Mauritius, and Réunion.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 9710)
Adults are found in aggregations near ledges and deep patch reefs (Ref. 9710). Benthopelagic (Ref. 58302). Known only from a few specimens. Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 13550).
