Habitat and Ecology [top]

Habitat and Ecology: Commonly inhabits rocky areas and intermediate biotopes. This species is most numerous over large rocks and boulders. Occurs in the extreme shallows to at least 40 m depths but is most common at 3–12 m. It is well known for its fin biting as well as scale eating habits (an opportunistic lepidophage). It is mainly attracted to displaying males in the rocky habitat and strikes them when they are preoccupied in defending their territories. It has been observed mimicking another species (P. longior) in Mbamba Bay so that it is able to approach its prey (P. longior) much closer for attack. It is likely that it mimics other species in other areas of the lake for the same purpose. It can also feed on plankton and aufwuchs. It is rarely observed over open sand. It is not territorial, and individuals are normally solitary. It can, however, be aggressive when it meets conspecifics. Due to its aggressive nature, this species is rarely exported for the aquarium trade. It is a polymorphic cichlid.
Systems: Freshwater
