Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 16 - 20. Scales on chest and belly are abruptly different in size compared to those on flank. No scales on cheek.

Essentially riverine with tendency to colonize quieter waters; near bands of reeds and vegetation fringing the river; very small eggs, plant and insect debris and small crustaceans found in stomach; most probably a mouthbrooder (Ref. 28906).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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