Africa: Lake Tanganyika and the Lukuga River (upper Congo River basin) (Ref. 5714, 52346).
Swamp-dweller (Ref. 6770). Juveniles are coastal and gregarious while adults wander over the sandy bottoms by themselves (Ref. 6770), in shallow inshore areas of the lake, in lagoons and river mouths (Ref. 4967). Feeds mainly on crustaceans and insects, along with some plants (Ref. 52307), but also a mollusc eater (Ref. 10616, Ref. 6316). Female carries the eggs (Ref. 1872).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00930 - 0.03905), b=3.01 (2.82 - 3.20), based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.44 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
