The population is estimated at 200–400 individuals.[6] Little is known about its reproduction, and attempts to breed it in captivity have failed.{{citation needed|date=April 2017}} The population is threatened by chance events and water extraction from the cave lake, which has resulted in a drop of the water level.[3] It is the only known cavefish in mainland Southern Africa.[7] See also
