A new species, Nanochromis teugelsi, from the Kasai River area in DR Congo has been described by Anton Lamboj and Robert Schelly. Published in Ichthyological Exploration of Freshwaters, the article can be found on the Researchgate.net website.

From the article, Nanochromis teugelsi was collected from protected backwater over sandy bottoms and some vegetation. The species appears to be a monogamous cave-spawner. Both parents protect the fry until they are old enough to be on their own. Other species of the Nanochromis genus are sometimes available on stock lists. N. transvestitus and N. splendens being the most common. Hopefully there will be more information on N. teugelsi when the species become more available in the hobby. To discuss N. teugelsi visit the West African Species forum.

CARES Exchange April issue is out

cares exchange

April marks the publication of the second issue of the CARES Exchange. The CARES Exchange a publication by the CARES Fish Preservation Program. The purpose of the CARES Program, with the help of hobbyists, is to create a stock of conservation priority species. Hobbyists simply devote some tank space to these endangered species and pass on offspring to other hobbyists. An article about the CARES Program can be found in the library.

The CARES Program was founded in 2004 and has helped distribute endangered species all around the world. Even if the original habitat of certain species is lost, the species live on in hobbyist’s aquariums. The CARES Exchange publication not only lists available species from CARES participants, but has several conservation related articles. If you would like to participate in the program check out the Exchange latest issue. You may find that rare species you’ve been looking for or you might just realize you have an endangered species you can help distribute.

Teleocichla prionogenys from South America

Teleocichla prionogenys is a species rarely seen in the hobby. Teleocichla is a relatively new genus with a handful of species, all which have been characterized by their small size and streamlined bodies. T. prionogenys grows to only about 3 inches in length. The fish in this genus have been commonly referred to as dwarf pike cichlids.

Information on Teleocichla prionogenys is limited. They live in the fast moving waters of the Tapajós River of Brazil. Females will stick their eggs to a protected surface and both parents will look after the young. Males can be quite territorial. To discuss this species visit the South American Cichlids forum.

Coptodon thysi guarding fry video

A great in the wild video by Adrian Indermaur showing a pair of Coptodon thysi guarding their fry.

Lake Bermin is a small volcanic lake in the Southwestern region of Cameroon. Despite measuring only 700 meters in diameter, it is home to nine endemic cichlid species. How such a small lake brought about so many different species is still up for debate. One of the nine species, Coptodon thysi, can be seen in the video above defending their fry. There isn’t much information on this species and they are very rare in the hobby. Unfortunately, C. thysi and all the other species from the lake are critically endangered due to pollution and sedimentation. Like other lakes in the region, Lake Bermin species are also threatened by large and sudden emissions of carbon dioxide. To discuss C. thysi and the other species from Lake Bermin visit the West African Species forum.

Enterochromis paropius is one of a few species who’s numbers appear to be growing in Lake Victoria. After almost disappearing following the introduction of the Nile Perch, E. papopius is bouncing back. Despite the encouraging details, this species is still at risk from the Nile Perch and hybridization due to cloudy waters.

Enterochromis paropius lives in large groups along the muddy bottom of Lake Victoria. Large groups have been found in Mwanza Gulf and may exist elsewhere in the southern portion of the lake. E. paropius is a detritivore, feeding on decomposing organic matter. In the aquarium, E. paporius is a peaceful species that does well in large groups. Even when spawning they are not known to be very aggressive. As the mature, males develop a well defined horizontal black stripe along the length of their body. Females are grey in typical Haplochromine fashion. To discuss Enterochromis paropius visit the Lake Victoria Basin forum. Additional pictures of this species can be found in the Species Profile.

Steatocranus gibbiceps from West Africa

Steatocranus gibbiceps is one of a handful of described species in the Steatocranus genus. The genus has been under revision for some time and there is still some confusion of what species are included. S. gibbiceps was first described in 1899. Males are larger than females and will develop an enlarged forehead as they mature.

Steatocranus gibbiceps is usually collected in Pool Malebo (Formerly Stanley Pool). Many species from the Congo River found in the hobby originate in and around this area. Pool Malebo is an unusual feature of the Congo River. The river widens and creates a lake-like area covering almost 200 square miles. With the swiftness of the currents in the Congo River it is not surprising that many species are collected from this area where currents are slower. To read more about Steatocranus check out the article titled Steatocranus: A Genus Review by Dave Hansen. Discussion can be done in the West African forum.

Tropheus sp. “Red” from Lake Tanganyika

Tropheus sp. “Red” (Lupota) is one of about a dozen “Red” Tropheus that were originally classified as a T. moorii variant. Color differences between the “Red” and moorii variants led to the distinction between the two species. “Red” species Tropheus have yet to be officially described, but include many variants from different locations. Images of the different variants can be found at the bottom of the Tropheus Profiles page.

In the aquarium Tropheus sp. “Red” (Lupota) is similar to all other Tropheus species. They are herbivores that are best kept in large groups to minimize aggression. The aggression can be intense until a pecking order is established. If diet and water conditions are right, Tropheus can breed readily. Young offspring join the colony without danger from larger members. To discuss T. sp. “Red” (Lupota) visit the Lake Tanganyika Species forum. The Tropheus Corner library section offers many articles about the genus.

Tropheops macrophthalmus from Lake Malawi

Tropheops macrophthalmus, formerly Pseudotropheus macrophthalmus, can be found in several locations throughout Lake Malawi. Despite being widespread, the largest concentrations are found on the eastern shores of Mozambique and Tanzania. Like other mbuna, T. macrophthalmus is a herbivore that finds food and shelter along the rocky, shallow shores.

Although not too common in the hobby, Tropheops macrophthalmus can be found. Males are a striking yellow with some blue in the fins and sometimes the head. Females are not very colorful. Due to aggression, it is best to keep a single male to multiple females. Tankmates should also be herbivores and of suitable aggression levels. Other species’ females should not be similar to T. macrophthalmus females and males should be of a different color or pattern. To discuss Tropheops macrophthalmus visit the Lake Malawi Species forum.

Gymnogeophagus balzanii from South America

Gymnogeophagus balzanii is a species a cichlid found in various countries in South America including Paraguay, Brazil, Uruguay and Argentina. G. balzanii is one of many species commonly known as eartheaters. They get this name because they scoop up sand in search of tiny bits of food. The sand is ejected through the gills and not actually eaten. The various species that make up the Gymnogeophagus genus are widely spread through the four countries mentioned earlier.

In the aquarium Gymnogeophagus balzanii isn’t very demanding. A sandy substrate is a must if you want to see their natural behavior. Some rocks and driftwood can be used, but plants are not recommended and they would probably be dug up. A diet of protein and plant matter like Spirulina is recommended. Males can get quite large reaching about 8″ and can be quite aggressive toward other fish and other males of the same species. Best kept in groups of a single male and multiple females. For more information check out the Species Article by Kaycy Ruffer. Discussion can be done in the South American Cichlids forum.

Steatocranus tinanti from the lower Congo River

Found in the area of Malebo (Stanley) Pool, Steatocranus tinanti sports the body of a fish born for fast moving waters. Its sleek, elongated body and reduced swim bladder allow it to “hop” along the river’s bottom without being swept away by the Congo River’s strong currents. S. tinanti is a cave spawner known to lay upwards of 100 eggs. Both parents will care for the young until they are old enough to be on their own.

In the aquarium, Steatocranus tinanti can be territorial when breeding. They will excavate shallow pits in sandy-bottom aquariums. Breeding is possible, but due to their shyness a species only tank is your best bet. Otherwise, their peaceful nature and hardiness make them compatible with many other species. The genus and this species is under revision and may be reclassified. To discuss Steatocranus tinanti visit the West African Species forum. Several articles on Steatocranus species can be found in the forum library.
