Heterochromis multidens is an African cichlid species that occurs in the central Congo Basin north of Pool Malebo , as well as in the Ubangi , Ngupaya , Tshuapa , Dja and Sanga .
features
Heterochromis multidens becomes a maximum of 30 cm long and has a typical, but relatively high-backed cichlid shape. The fish are inconspicuously colored gray or brown. The dorsal fin can be lined with red. There is a black spot in the back of the base of the dorsal fin. Young fish often show a dark longitudinal band in the middle of the flanks. Old males have a distinct forehead hump, while females are a little more colorful.
- Fin Formula : Dorsal XIV / 14-15; Anal III / 8-9.
Heterochromis multidens is a substrate spawner and open breeder.
Systematics
Heterochromis multidens was by the French in 1900 ichthyologists Jacques Pellegrin as Paratilapia multidens described and 1922 by his British colleague Charles Tate Regan in the genre Heterochromis found that since monotypic remains. Heterochromis means "other chromis" ( Greek : heteros = other); Chromis is now a genus of damselfish, in which cichlids were also classified in the past. Heterochromis multidens is probably the most original cichlid still alive today and is classified either as a sister species of all New World cichlids or the other African cichlids ( Pseudocrenilabrinae ). The Swedish ichthyologist Sven O. Kullander placed it in 1998 as a sister group of the New World cichlids in an independent subfamily, the Heterochromidinae. More recent studies tend to support the thesis that Heterochromis multidens is the most primitive African cichlid and the species is classified in a tribe Heterochromidini at the base of the Pseudocrenilabrinae (see cladogram ).
Danger
In the Red List of the IUCN of the status of the species is given as safely (Least Concern).
