This unusual cichlid fish from Lake Malawi was imported for the first time to Denmark by Carstens Dyrehandel, a specialized cichlid store in Aalborg. The slender form and small mouth make this cichlid appear more like a Benthochromis or Cyprichromis from Lake Tanganyika. Even its behavior is similar to the pelagic (open water) cichlids from that lake. The adult size is around 7 inches (18 cm). Supposedly, this fish is the most common cichlid in the lake, yet strangely, it was described by Turner only in 1994. The species occurs in the open water in depth up to 200 meters. Diplotaxodon are mouthbrooders, producing small clutches of eggs (15 to 20). Like many Utaka cichlid fish, the males of courting Diplotaxodon are supposed to develop a brilliant yellow blaze on the forehead. Hopefully, this unusual Malawi cichlid fish will also be imported to the United States in the near future.
In the aquarium, Diplotaxodon behave more like the pelagic species from Lake Tanganiyka than any Malawi cichlid fish. They should be kept in groups of at least 12, with only few large rocks in the aquarium. They feed on small live foods of any kind but will also readily accept flakes and other foods.
The number of species of peacock bass keeps growing as more species are identified. In 2006, Dr. Sven Kullander described nine new Cichla species to add to the six previously described ones. The blue peacock bass (C. piquiti) is one of the nicest species in this group of giant cichlids that are becoming increasingly popular with large cichlid fish hobbyists. Further research will likely mean more species will be described in the coming years. For now, the peacock bass family looks as follows.
The nine new species of Cichla (peacock bass) are: C. jariina from Rio Jari, Para State; C. kelberi from Rio Tocantins and introduced to Bahia; C. melaniae from the lower Rio Xingu; C. mirianae from upper Rio Xingu and Tapajos in Mato Grosso; C. pinima from Rio Curua Una, Xingu and Tapajos; C. piquiti from Rio Araguaia and upper Rio Tocantins; C. pleiozona from Rio Guapore and parts of Mato Grosso; C. thyrorus from upper Rio Trombetas and C. vazzoleri from the lower Rio Trombetas.
The six previously described species of Cichla are: C. intermedia from the Rio Orinoco basin; C. monoculus from all along the Amazon mainstream; C. nigromaculata from Rio Orinoco, Cassiquare and Rio Negro; C. ocellaris only from the Guyanas; C. orinocensis from the Rio Orinoco basin and Rio Negro and C. temensis from Rio Orinoco and Rio Negro.
All peacock bass are huge cichlid fish that will grow more than 2 feet in length. For long-term care, they require aquariums of 300 gallons or more (for a group of six to eight fish). Most species will feed on anything that moves, but they prefer live fish or fresh shrimp as their diet.
