[2] The mouth is protrusible and forms a suction tube which is used for sucking in pelagic zooplankton.

The female protects and broods the eggs in her mouth until the fry hatch and are able to swim on their own.

At that point, the female releases the eggs into a rocky area for the fry's protection, and leaves them there on their own.

The most prominent is Cyphotilapia frontosa, which lives in deep water most of the time, but comes up to feed on C. leptosoma primarily at dawn.

[4] C. leptosoma is endemic to Lake Tanganyika from the southern part in Zambia and along the eastern shoreline into Tanzania.
