Metriaclima koningsi, formally known as Metriaclima sp. 'membe deep', has been officially named and described. Named after Ad Konings, M. koningsi is found around the islands of Likoma and Maingano in Lake Malawi. This species has a similar color pattern to Pseudotropheus sp. "polit" but can also be more blotchy like Metriaclima sp. "Msobo". M. koningsi males have the blue and black coloration while females and young males are yellow/orange.
The species' description can be found on the Mapress site, but it is behind a paywall. Metriaclima koningsi can be quite aggressive, especially with members of its own species. Best kept in groups of one male to multiple females. Like other mbuna, their diet should include plenty of vegetable/plant matter. An adequate tank size is recommended with lots of hiding places. Other species, like Chindongo (Pseudotropheus) saulosi and M. sp. "Msobo" should not be tankmates since the females look very similar.
