Nimbochromis livingstonii, is a freshwater mouthbrooding cichlid native to Lake Malawi. It is also found in the upper Shire River and Lake Malombe. They are found in inshore areas of the lake over sandy substrates. Maximum reported length of male fish in the wild is 9.8 in while females reach 7.9 in. Colouration is variable but typically mottled brown and white. The dorsal fin may also show blue coloration while maintaining an orange to red band and sometimes a white line. Adult males frequently “color up” in response to changing conditions and rapidly change from spotted camouflage to brilliant blues and greens and may even exhibit a pale golden tone. Breeding males turn a dark blue which almost completely obscures their blotched pattern. The anal fin is usually orange to red. Females are similar, but usually lack the yellow “egg spot” markings on the anal fin. Juveniles display a brown and white spotted pattern.
Wild fish feed primarily on small fish, in particular Lethrinops spp. Aquarium specimens have been observed to lie on the substrate as if dead, waiting for small fish to come close in search of a meal. When a suitable target comes into range, the fish quickly lunges at the prey and usually swallows it whole.It is this unique hunting method that gives the fish its local name, kalingono, which means “sleeper”.
Males are polygamous and will mate with multiple females. This species is a mouthbrooder with the female incubating up to 100 eggs until they hatch and the fry become free swimming.
