Hemitaeniochromis Hemitaeniochromis Hemitaeniochromis is a small genus of cichlid fishes endemic to Lake Malawi in east Africa. The genus is distinguished from other genera of Lake Malawi Haplochromini by details of its melanic color pattern and by its dentition. The color pattern includes (1) a midlateral horizontal stripe starting at least an eye length behind the operculum, this stripe broken into separate spots at least on its front half, more nearly continuous on its rear half, extending to the end of the caudal peduncle; (2) a second (supralateral) stripe above the midlateral one that is only on the front part of
Apistogramma eremnopyge Apistogramma eremnopyge Apistogramma eremnopyge is a species of cichlid. It is only known from the Rio Pintuyacu, a tributary of the Rio Itaya near Iquitos, Peru. Most of the tributaries of this river system carry acid blackwater (pH ~ 5). This is a small cichlid, standard length which can be easily distinguished from its congeners by the presence of a prominent dark blotch on the lower part of the caudal peduncle in both sexes. The male is strikingly coloured with vivid blue and red patterning on the cheek and operculum and maroon, orange and blue colouring on the dorsal fin.
