In coastal rivers and creeks (Ref. 42576). Pair-bonding, ovophilic mouthbrooder (Ref. 52307, 81260) with delayed uptake (Ref. 81260). Spawns on open substrates; both parents brood offspring (Ref. 81260).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming Fec<1000).

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