Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Africa: endemic to Lake Tanganyika, patchy distribution in the northern part of the lake (Ref. 6770, 46829).

Biology     Glossary (e.g. epibenthic)

Prefers the upper rocky habitat where it feeds on the algae attached to the rocks (Ref. 7343, 46829). Occurs to a depth of 30 m; maternal mouthbrooder; females guard their offspring for a few days after releasing them for first time (Ref. 46829). Aquarium keeping: many females for one male; minimum aquarium size 150 cm (Ref. 51539).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01450 (0.00585 - 0.03592), b=3.03 (2.82 - 3.24), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
Price category (Ref. 80766):   Unknown.
