Sarotherodon knauerae was discovered about 5 years ago in the small, isolated Lake Ejaghan. Unlike other lakes in the region, Lake Ejaghan did not form inside a volcanic crater. Instead, the oval shaped Lake Ejaghan is most likely the result of a groundwater solution basin formed during the last Ice Age.
Lake Ejaghan does not have an inflow and its outflow is separated from the Munaya River by a waterfall. These features separated Sarotherodon knauerae from other fish in the region. S. knauerae is the smallest of all Sarotherodons reaching only about 3″. Rarely seen in the hobby, S. knauerae is endangered by pollution and sedimentation. In the lake, S. knauerae feeds on the detritus and spends most of its time in the shallower waters of the lake.

Thoracochromis brauschi is a species found in the Fwa River region of the Democratic Republic of the Congo (aka Zaire until 1997). There are several species of cichlids in the Fwa River, but T. brauschi is the best known in the hobby.
Thoracochromis brauschi, often called the “blood throat” cichlid, is rarely found on stock lists despite its attractive and unique coloration. Males display a bright red color from the bottom of their mouth all the way through their pelvic fins. Females are drab and do not display the “blood throat” colors. T. brauschi is a mild mannered fish that rarely displays aggression toward other species. This makes them great additions to many community setups. To find out more about Thoracochromis brauschi check out the Species Article by Greg Steeves. Discussion on this species can also be done in the Lake Victoria Basin, West African, Madagascar & Asian Species forum.

Five new Gymnogeophagus species have been described in the Brazilian Neotropical Ichthyology journal. Gymnogeophagus are known as eartheaters for their specialized feeding behavior and are found in river basins of southern Brazil, Uruguay and Paraguay.
The Cichlid-Forum staff would like to wish everyone Happy Holidays. It’s been another terrific year and we would like to wish every forum member, participant and visitor a festive and safe holiday season.
I would like to take a moment to thank all the moderators who keep the forum running. Without your time and devotion this site would not exist today. Also, thanks to the support staff that addresses all of our issues. Here is to another great year in 2016.

Lipochromis sp. “Matumbi hunter”, like some other Lipochromis, is a paedophageous. They feed off of other fish’s eggs and young. While Lipochromis sp. ‘Mwanza’ engulfs a female’s mouth and sucks out her eggs, L. sp. “Matumbi hunter” uses a ramming technique to force females to spit out their eggs. Greg Steeves has written a short article describing the Lipochromis and recounting when he witnessed L. sp. “Matumbi hunter’s” feeding technique. The new L. sp. “Matumbi hunter” article can be found in the library along with a couple more pictures. You might also want to check out the L. sp. ‘Mwanza’ article by the same author. Discussion on all Lipochromis can be done in the Lake Victoria Basin forum.
Aulonocara baenschi is a stunning peacock from Lake Malawi. Males sport a bright yellow body with blue around the cheeks. Like all Aulonocara, only the males display bright colors while the females are brown with some vertical banding. A. baenschi is a little smaller than the other peacock species. In the wild along the shores of Nkhomo Reef, A. baenschi feeds be sifting through the sand looking for small creatures. In the aquarium, sand is recommended so this behavior can be seen. Males will also excavate a small depression in the sand for spawning.
In addition to a sandy substrate, a few rock formations will provide females some cover. Aulonocara baenschi should be kept in groups of one male and multiple females. Although not very aggressive, multiple males are not recommended. Other species of Aulonocara should be avoided as females look very similar and crossbreeding is a possibility. A diet high in protein is best. Discussion on Aulonocara baenschi can be done in the Lake Malawi Species forum.
The different subspecies of Pseudocrenilabrus philander are widely distributed throughout Central and Southern Africa. Currently only 3 subspecies have been identified, P. p. philander, P. p. dispersus and P. p. luebberti. There may be up to a dozen separate populations throughout Africa. The picture above is supposed to be from Guma Lagoon in Botswana. To discuss Pseudocrenilabrus philander, visit the Lake Victoria Basin, West African, Madagascar & Asian Species forum.

A new study may may shed some light on the incredible diversity of cichlids in Lake Malawi. The question of how over 1000 species evolved in a single lake may have been answered by core samples obtained through the Lake Malawi Drilling Project. Core samples from the last 1.3 million years of the lake’s history show drastic changes in water levers, pH and salinity.
Dry periods in Lake Malawi’s history have dropped waters levels over 200 meters a couple dozen times. During the low level periods, habitats changed as the water receded and fish became isolated into smaller lakes. As wetter periods returned and lake level’s rose, once isolated species once again were joined. All of these extreme changes led to fish who are also able to change in order to survive. The full, unrestricted article titled “Continuous 1.3-million-year record of East African hydroclimate, and implications for patterns of evolution and biodiversity” can be found on the National Academies of Science website.
3rd Place Discus red – Marc Volders Belgium. Capture from video.
The 2nd European Discus Championship took place in Dortmund, Germany, 2014. The video below shows some of the highlights from the competition.
Discus is the common name for cichlids belonging to the Symphysodon genus. Discus originate from various rivers and lakes in the Amazon Basin. In captivity, discus have been bred to enhance particular colors and patterns like the ones seen in the video. Keeping discus is not recommended for novice hobbyists. They require more attention to water quality and diet than most other cichlid species found in the hobby. For information of discus, check out the articles written by Ryan Williams – My Experience Raising & Keeping Discus and Breeding Disucs From a Beginner’s Perspective. Discussion on discus can be done in the South American Cichlids forum.
Ptychochromis mainty from southeastern Madagascar has been described in a recent publication by Magnolia Press. Unfortunately, the article is behind yet another paywall. The first page of the article can be found HERE and some more information about P. mainty can be found on the One species a day blog.
Four specimens were collected from the Fort Dauphin region of southeastern Madagascar and are the basis for the description of Ptychochromis mainty. Most of the species of cichlids from Madagascar are at risk of extinction. Ptychochromis onilahy was once collected in 1962 and has never been seen again. A world-wide search for specimens of Ptychochromis insolitus in 2013 after the last female died in captivity led to finding 18 individuals in wild. Including P. mainty, there are 10 described species of Ptychochromis. Most are under threat due to habitat destruction or other introduced species. Fish from Madagascar can be discussed in the Lake Victoria Basin, West African, Madagascar & Asian Species section of the forum.
