features
Maylandia greshakei becomes 13.5 to 15 cm long and has a typical Mbuna shape. The upper half of the body of sexually mature males is colored metallic light blue to blue-gray. The color becomes increasingly gray towards the abdomen. There are six to eight cobalt blue transverse bands on the sides of the body. The head is blue-gray, the gill covers blue, the throat white. The dorsal fin is rust-red to orange, the first fin rays and the tips of the fin membranes are whitish to silvery blue. In the caudal fin, the fin rays are white, the fin membranes, especially in the upper half, orange-red. The bluish transparent anal fin shows four to seven small egg spots. Females are similarly colored, but sometimes also of a rust-brown or wine-red basic color. Your anal fin has up to ten egg spots.
The males of Maylandia greshakei differ from Maylandia mbenjii mainly in their less blunt head and more intensely colored caudal fin.
The jaws have two to three rows of teeth. The teeth of the outermost row of teeth are usually two-pointed, some at the back are single-pointed. The teeth of the inner rows of teeth are three-pointed. On the first gill arch there are 8 to 12 gill rakes on the ceratobranchial, 2 to 3 on the epibranchial and one between these gill arch elements.
- Fins formula : dorsal XVII – XVIII / 8–9, anals III / 6–7, pectorals 11–14.
- Scale formula : SL 30–33.
Way of life
Maylandia greshakei feeds mainly on phytoplankton , territory-owning males more on growth. Like almost all Malawi cichlids and all mbuna, Maylandia greshakei is an ovophilic mouthbrooder in which the female takes care of the brood.
