Parananochromis longirostris can be found in rivers and streams mainly throughout Southwestern Cameroon and Northern Gabon. This West African cichlid is not often seen by hobbyists, but it is occasionally available on stock lists. Not necessarily the best choice for beginners as they are prone to infections if water quality isn’t ideal. Although not aggressive males can reach 6+ inches.

Parananochromis longirostris form monogamous pairs and usually spawn in caves. Both male and female will look after the young until they are old enough to go out on their own. Clean, soft water is a must to encourage breeding. Temperatures should also be kept slightly cool. More details are somewhat limited on this species. If you are looking for something rare and unusual from West Africa, P. longirostris might be the ticket. To discuss this species visit the West African Species forum.

Aequidens superomaculatum described

A paper has been written describing a new species, Aequidens superomaculatum. Most Aequidens species can be found in the Amazon and Orinoco River basins. Several species of Aequidens have been moved to other genera as classifications are sorted out. A. superomaculatum shares many physical attributes as other Aequidens, but differs enough to receive its own species name. The specimens were collected from several locations in rivers and canals in southern Venezuela between Brazil and Colombia.

The publication appears to be only available in Spanish. For those with just a little understanding, enough can be understood to find out what sets Aequidens superomaculatum apart from other similar species. The publications can be found at To discuss A. superomaculatum visit the South American Species forum.

Ad Konings

Between now and July 7th we’ll be doing a short profile on this year’s American Cichlid Association 2016 Convention speakers. Starting off with a person synonymous with cichlid keeping, Ad Konings. Born in the Netherlands, Ad’s passion for cichlids began at the age of 14. Although he originally studied medical biology at the University of Amsterdam, Ad is now one of the most recognizable names in ichthyology. In 1991 Ad started his publishing company, Cichlid Press and published his first of many cichlid books, Cichlids Yearbook, vol. 1.

In 1996 Ad Konings moved to El Paso, Texas. He has published many of the best books on cichlids and continues his research on the subject. Ad is also very involved with the Stuart M. Grant Cichlid Conservation Fund. Ad’s lectures are always exciting, informative and insightful. Join him and other speakers at this years ACA 2016 Convention.

The Tropheus genus from Lake Tanganyika is made up of only a handful of different species. However, those species are further defined by dozens of different variants. Pictured above is the Tropheus moorii Chaitika, commonly known as the Blue Rainbow. There are several variants commonly referred to as Red Rainbow, but only one Blue Rainbow.

Tropheus have a reputation of being best kept by advanced hobbyists, but with an understanding of their requirements and a willingness to meet thos needs, anyone can keep Tropheus. If you are interested in keeping a species like Tropheus moorii Chaitika check out the Tropheus Corner where you will find a variety of articles. To discuss any Tropheus species visit the Lake Tanganyika Species forum.

Amazon River needs to be connected

In past blogs the issues of dams being build on the Amazon River have been discussed. On one side there is the threat to the local ecology and on the other the increase need for sustainable energy. A recent study published in the journal Biological Conservation finds that separate areas along the river need to periodically flood and mix. This mixing of distinct regions leads to healthy and genetically diverse species of fish. Dams will prevent seasonal flooding which can have long-term effects not only on the native wildlife, but also on commercial fisheries.

For more information on the possible dangers dams pose to the Amazon River, read the study on the website. To discuss cichlid species from the region visit the South American Species forum.

The staff at would like to wish all the special moms out there a happy Mother’s Day.

Pictured above is a Steatocranus bleheri with some of her fry. S. bleheri are found in the fast moving waters of the Luapula River System which eventually feeds into the Congo River. Although not very common in the hobby, Steatocranus keepers love their personalities and unusual behaviors. To find out more about S. bleheri check out the article title A Rheophilic Suprise, Steatocranus bleheri by Dave Hansen. To discuss this and other rheophilic species visit the West African species forum. Again, happy Mother’s Day!

Invasive crayfish threaten Lake Tanganyika

There is a new threat to Lake Tanganyika. Invasive crayfish have been making their way toward the lake. When crayfish get into bodies of water for the first time, their impact on the local ecology is devastating. They are voracious eaters that will consume algae, plants, invertebrates and fish.

Past experiences with the introduction of crayfish into African waters have all ended badly. Even the Okavango Delta, one of the Seven Natural Wonders of Africa, is at risk from the invading crayfish. To read more about the invasive crayfish and their past and potential impacts check out the article on The Huffington Post.

Metriaclima fainzilberi OB “Charo”

Metriaclima fainzilberi is a Lake Malawi mbuna collected from various locations. Pictured above is an orange-blotched male from Charo on the western side of the lake. While most M. fainzilberi males are blue with black stripes, OB coloration does rarely happen.

Metriaclima fainzilberi is a herbivore and should be fed a diet high in plant matter. Although not especially aggressive toward other species, males can be very aggressive toward other M. fainzilberi. Care should be taken to ensure females and subdominant males have room to run and hide. Tankmates should be chosen to be tolerant of aggression as well as having a compatible diet. To discuss M. fainzilberi visit the Lake Malawi Species forum.
