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).

Estimates based on models

Preferred temperature (Ref. 123201): 19.2 - 21.2, mean 19.3 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01820 (0.00804 - 0.04119), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.0 ±0.1 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
