| Range Description: |
The Upper and Middle Zambezi system, including the Okavango, and in the upper Save-Runde system in Zimbabwe. Specimens from the Mwekera tributary of the Kafue may be a distinct species (Tweddle et al. 2004).

Habitat and Ecology
[top]
| Habitat and Ecology: |
Occurs in a wide range of habitats, including fringes of rapids, lagoons and aquatic vegetation. Not generally found in small tributaries and is thus a species that prefers larger water bodies than other small cichlids in the Zambezi system (Tweddle et al. 2004).
|
| Systems: |
Freshwater |
| Major Threat(s): |
May possibly be impacted by competition with invading Oreochromis niloticus from fish farms in the catchments.
|
Conservation Actions

| Conservation Actions: |
The species has little protection other than in Okavango Delta reserves.
