They are known as sleeper cichlids or kaligono ("sleepers" in Chichewa) due to their unique hunting behaviour. These piscivorous species are often seen lying motionless on the lake bottom near rocks where mbuna live, even adopting an unusual sideways position rarely seen in living fish. If smaller fishes approach, the Nimbochromis will "wake up" and try to seize them. Their coloration has an irregular dark cloudy pattern on lighter background; for one thing, this provides camouflage, but it is also suspected that it is – at least in some – evolving into aggressive mimicry (apparent death) by imitating a rotting fish carcass and thus luring scavengers to their demise. SpeciesThere are currently five recognized species in this genus:[1]
