More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 4 - 40 m (Ref. 7247). Tropical

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. 90102)
Adults inhabit outer reef slopes and deep lagoons (Ref. 9710). They form small to moderate aggregations on reef crests with moderate currents (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). Diurnal species (Ref. 52881).
