Habitat and Ecology [top]

Habitat and Ecology:	The habitat of Tropheus is solid rock, either anchored and part of the hard core of the coast interlocking rubble, or even the sandstone slabs lining a sand beach. Loose pebbles rolling about in the surf and silted-over habitats are avoided. The vertical depth range depends on the depth to which the epiphytic algae are growing and this varies from one species to another and from one part of the lake to another.
Systems:	Freshwater
