Native range
Widely distributed in deeper sandy regions of Lake Malawi, East Africa.
Natural habitat
Sandy habitats with scattered rock structure. The fish naturally uses sand as camouflage when ambushing prey; provide open sand and stable large caves/outcrops.
Diet & feeding
Predatory but readily takes prepared food. Use quality carnivore cichlid pellets plus varied frozen aquatic foods and occasional plant-containing foods for balance.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Mature males become strongly blue, particularly on the head; females retain the yellow-brown giraffe pattern.
Breeding
Maternal mouthbrooder. Females pick up externally fertilised eggs and incubate them for several weeks before releasing developed fry.
