Bathybatini  Bathybatini is a tribe of cichlids endemic to Lake Tanganyika in Africa. They are mostly found in relatively deep waters and mainly feed on fish ("Bathybates" and "Hemibates") or plankton ("Trematocara"). They are mouthbrooders. This tribe is sometimes restricted to "Bathybates", in which case "Hemibates" is in Hemibatini and "Trematocara" in Trematocarini.
