Description

Poll's Tropheus is a cichlid endemic to Lake Tanganyika in East Africa. The species reaches about 16 cm and has a stocky, brown-grey body with faint cross-bars. It inhabits the rocky shore zone at depths of six to ten metres and is strongly site-attached: even when pursued it seldom strays more than six or seven metres from its spot. With its inferior mouth it grazes the algal layer (aufwuchs) from rocks. Like other Tropheus species it is a maternal mouthbrooder. In the aquarium it is prized but markedly territorial and aggressive.
