A new species of Apistogramma has been described in a publication by Ricardo Britzke, Claudio Oliveira & Sven O. Kullander. Titled Apistogramma ortegai (Teleostei: Cichlidae), a new species of cichlid fish from the Ampyiacu River in the Peruvian Amazon basin, this species brings together what was thought to be two separate species; Apistogramma sp. "Pebas" and "Papagei". The differences between the two weren't significant enough for them to be considered two separate species.
Apistogramma is a genus consisting of about 100 separate species found in the rivers and streams of South America. They are very colorful and can be housed in smaller tanks. For more information on Apistogramma, take a look at all the South American Dwarf articles in the Library.
