Morphology | Morphometrics
Feeds on planktons (Ref. 89972). Diurnal species (Ref. 54980). 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).

Bayesian length-weight: a=0.01738 (0.00792 - 0.03811), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
