Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 7.5 - 8.5; dH range: 10 - 20; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 24°C - 26°C (Ref. 2060); 3°S - 9°S
Africa: endemic to Lake Tanganyika (Ref. 5694); in the Lukuga River (Lake Tanganyika outflow) known up to the Kisimba-Kilia rapids (Ref. 93587).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 5694)
This is one of the smallest and hardiest species in Lake Tanganyika along with Pseudosimochromis marginatum (Ref. 6770). Known from sandy and rocky areas (Ref. 7343). It is very intolerant of any other rockgrazer, less so of the other species, and very territorial and aggressive toward its conspecifics (Ref. 6770). It cleans off a patch of ground between rubble to breed (Ref. 6770). Females brood their young in the mouth (Ref. 86760).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Fec=50).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
