Trematocara is a genus of cichlids endemic to Lake Tanganyika in Africa. They are relatively small, up to long, and slender in shape.Smith, M.P. (1998). Lake Tanganyikan Cichlids, p. 9. These schooling, light-shy fish are typically found in relatively deep waters, but move closer to the surface at night to feed on plankton. They are mouthbrooders.
