Present on the bottom of deep water to 150 m but most common in sub-littoral areas; very common in deep water (Ref. 4967). Specialized toward a life on the sandy bottoms (Ref. 6770). Upstream spawning migrations have been reported (Ref. 78218, 93972). Omnivore (Ref. 78218). Feeds on small fishes (usually Lamprologus spp.), ostracods, and larvae of dragonflies (Ref. 6868, 36901).

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=0.00891 (0.00399 - 0.01990), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.7 ±0.61 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).

Price category (Ref. 80766): Unknown.
