About the species

Nimbochromis venustus, the venustus or giraffe cichlid of Lake Malawi, is among the most recognisable and widely kept large haplochromine cichlids in the hobby: males in breeding dress glow an intense peacock-blue over a warm yellow ground, while both sexes carry the dark, giraffe-like blotching that gives the fish one of its trade names. It is a patient, specialist hunter that earns its place in the Nimbochromis lineage of ambush predators — capable of settling motionless onto the sand, mimicking a dead fish, until a smaller cichlid draws close enough to seize.
