Tylochromis polylepis is a fish from the cichlid family. It lives only in Lake Tanganyika in Africa and is distinguished by a very large number of scales on the body.
Tylochromis polylepis differs from related species by a very large number of scales in the lateral line. The fish is important for Lake Tanganyika because it participates in food chains and eats growths on stones.
Immature form that undergoes metamorphosis before adulthood.
