Extremely common in lake shores; juveniles occur in the shallows close to shore, whereas adults form large schools over deep water adjacent to rocky cliffs. Main food of the Foi people who live along the shores of Lake Kutubu (Ref. 2847). Eggs are guarded and fanned by the male parent (Ref. 205).

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=0.01660 (0.00638 - 0.04320), b=2.99 (2.76 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).

Catégorie de prix (Ref. 80766): Unknown.
