Populations

• Loiyangalani, Lake Turkana

Given as 'west shore of Lake Rudolf'. This lake is now named Lake Turkana.

Endemic to Lake Turkana, northern Kenya - southwestern Ethiopia.

The lake is presently alkaline but has changed through it's evolution due to inflow of waters. Volcanic ash is known to have been deposited on the lake. High saline areas formed in lagoons with a rich coating of blue/green algae. Reed beds are reportedly around its edges in places.
Sympatric sp. Lacustricola jeanneli.

Discovered on a collecting expedition to (the then named) Lake Rudolf in 1930 - 31.
Probably only one collection after this for the hobby which didn't last long in captivity.

No reports available. The water from the lake is probably hard / alkaline. The addition of salt to the water would be beneficial.

The lake is known to contain Ostracods which may form part of their diet.
Cichlids are endemic as food fish in the lake.
