Ice Blue Mbuna - Pseudotropheus Sp

Tank Setup:

In the wild, this stunning species is found over rocky habitats where it feeds mainly on the phytoplankton in the water column. It belongs to the Mbuna group of cichlids. The aquarium should be at least 4ft long and aquascaped to emulate that rocky reef effect. Decor such as ocean rock can be used to build sturdy structures which stretch from the base of the tank to near the surface of the water. These structures should be built with the purpose of creating many crevices for the fish to explore but constructed in such a way so as to keep the rocks stable if the fish start to dig around and underneath them. Although a substrate of coral sand or Aragonite is often recommended to help to keep the water hard and alkaline, Mbuna feel safer and show better colours over a darker substrate. The Aragonite or coral sand can always be placed into a mesh bag and kept inside the external filter for buffering purposes.

Tank Mates:

It is best to keep one male with several females (keeping just one will result in continual harassment and possibly death) and these can be kept successfully alongside other outgoing Mbuna. Other Maylandia species are best avoided though, particularly those of similar appearance, as males will respond most aggressively towards look-a-likes. Many Maylandia species are also capable of cross-breeding, something which should be avoided to keep the species pure. Maylandia greshakei is listed as "Vulnerable" on the IUCN redlist for endangered species. This is due to both the fishing of these cichlids for food and for their export into the aquarium trade. It is therefore preferable to purchase tank-raised specimens wherever possible in order to safeguard the wild population and help to prevent it from becoming a species that is more highly threatened. Fortunately this is a commonly seen species, especially the albino form. 

Diet:

The diet should be primarily vegetarian. Foods rich in animal protein could cause Malawi Bloat, which can be fatal. A good quality Spirulina-based green flake should be mixed with a standard quality flake food, and offered along with appropriately sized granular foods specifically developed for Mbuna. An occasional treat of Mysis shrimp can be given, but this should only be offered very occasionally. Vegetable matter such as cucumber, blanched spinach and romaine lettuce can be fed on a regular basis.
