Lake Malawi harbors one of the most interesting and colourful cichlid fish communitis on Earth. More than 850 species are currently recognized, almost all of them found only in this lake and nowhere else! Many of these cichlids are very popular among aquarists, as they are easy to maintain and breed in captivity. This third, revised, edition of the definitive study of Lake Malawi cichlids discusses and illustrates more species than any previous publication.
