Marine; reef-associated; non-migratory; depth range 3 - 33 m (Ref. 7247), usually - m (Ref. ). Tropical; 0°C - ; 21°N - 13°N

Maturity: Lm ?  range ? - ? cm

Adults occur in exposed seaward reefs, on relatively barren gently sloping terraces with scattered low-profile corals. Feed on zooplankton found 1 to 2 meters above the substrate (Ref. 7247). 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).

Bayesian length-weight: a=0.01479 (0.00674 - 0.03244), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.45 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
