Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce pélagique. Tropical; 3°S - 9°S
Africa: endemic to Lake Tanganyika, occurs in the southern half of the lake (Ref. 46829, 93918). One juvenile was collected on the western coast of the lake, near Kalemie (Ref. 93918).
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 16.4 cm SL mâle / non sexé; (Ref. 5678)
Pelagic species (Ref. 6770) occuring in the rocky habitat (Ref. 46829). Scale-ripper (Ref. 6770, 46829). Caught at depths from 60-100 metres (Ref. 93918), but has also been seen in the shallow rocky habitat (Ref. 46829). Breeding behaviour is interesting as it involves a pair bond even though they are mouthbrooders in which the female broods the eggs (Ref. 466829). Come to shoreline to release their fry (Ref. 6770).

Niveau trophique (Ref.
69278): 4.4 ±0.80 se; based on food items.
Résilience (Ref.
