Tanganyika blackfin  (Altolamprologus calvus)

Description

Altolamprologus calvus belongs to the Cichlidae, a family of freshwater fish that have adapted to a wide range of narrow ecological niches, resulting in the evolution of a huge diversity of species that live in close association (3). This species has a large mouth and a compressed body, with a large dorsal fin running along the entire length of the back (4). Like many cichlids, Altolamprologus calvus occurs in a number of different colour variations, including black, light grey and yellow (2) (3).
