Williams mbuna

William's mbuna (Maylandia greshakei), also known as Red Top Ice Blue Zebra mbuna or ice blue zebra or the Pseudotropheus ice blue among the aquarium enthusiasts, is a species of cichlid fish endemic to Lake Malawi where it is only found at Makokola in the southeastern arm of the lake. Try to avoid keeping this fish with other Mbuna of a similar colouration as this can invoke aggression to the other species. Provide plenty of rock work in the tank and regular water changes will be required to keep the fish happy.
