Conservation: Metriaclima greshakei est évalué par l\'Union Internationale pour la Conservation de la Nature dans la Liste Rouge des espèces menacées comme étant (VU) Vulnerable (2006). M. greshakei is a common resident of Makokola Reef, but it is not found at any other location in the lake. This narrow endemism led to its assessment of Vulnerable, but since the species is not targeted by local fishermen (too small and difficult to catch between the rocks) and barring a natural disaster that would destroy the reef, I would suggest that the species should be classified as Least Concern.
