Africa: Endemic to the northwestern part of Lake Tanganyika.

These fish are hardy, peaceful toward other species and highly intelligent. They are microfeeders and not carnivorous. In the wild, they often stay in deep water and never come to the surface to feed. They never swim in midwater but are typical rock-dwellers. Ventures into the open but never far from the rock cover. Breeds in crevices and caves (Ref. 6770). Monogamous pairs are most common (Ref. 54944).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01235 (-0.16179 - 0.18649), b=3.00377 (2.90675 - 3.10079), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.5 ±0.00 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 70).

Vulnerability (Ref. 59153): Low vulnerability (15 of 100) .

Price category (Ref. 80766): Unknown.
