Large quantities of dead fish have washed up along the shores of the Kironga district in the north part of Lake Malawi. This follows sightings of dead fish on other shores around the lake. The Malawi government is investigating to determine the cause of the fish deaths. A recent spill at a nearby uranium mine is being looked at as a possible cause. The story about the untreated radioactive material that leaked into Lake Malawi can be found HERE. The story about the dead fish and the government investigation into the causes can be found HERE.
Most people have seen pictures of the Anglerfish. These fish get their name from a modified ray with luminous flesh that they dangle to attract prey. These fish also look very scary with their strange shapes and long sharp teeth. However, none of these things come close to what really makes them strange. When scientist first started capturing these fish they noticed the female specimens had parasites attached to them. Turns out that in order to reproduce, males seek out and bite the females. They then release an enzyme which fuses the male to the female until the male is completely dependent on the female for nourishment. THe male even loses most of its organs in the union. In return, the male provides the female with sperm for reproduction. The male will remain attached to the female until she dies taking him with her.
A series of videos show the best entries in last year’s JBL Biotope Aquarium Design Contest. First place went to an Australian biotope, but 3 out of the top 5 were cichlid biotopes. Biotope aquariums are designed to recreate the natural environment of the fish that live in the aquarium. Not only does it provide the best opportunity for the fish to feel at home, but it allows the fish to demonstrate their natural behavior in what would be their natural environment.
Second place of the biotope aquarium design contest went to an entry modeled after the Nun River basin in Nigeria (video below). Among the tank inhabitants are the dwarf cichlid species Pelvicachromis pulcher

Mongabay.com has created a list of 10 rainforests things to watch in 2015. The Amazon Rainforest is prominent on the list and the outlook is mixed. Some gains in preserving the parts of the rainforest should come into effect in 2015. Unfortunately deforestation in Peru and Bolivia is on the rise. Brazil has shown an overall reduction trend in deforestation, but the country’s continued construction of dams along several rivers is posing a threat to the Amazon Rainforest and the many cichlid species that live within the various rivers.
Almost two years ago we did a blog about an out-of-the-ordinary species from a small crater lake in Cameroon. The species is only one of 11 native cichlid species found in the lake. Thanks to Troy Veltrop, we now have a detailed article on Pungu maclareni.
Lake Barombi Mbo formed in the crater of a volcano on the western part of Cameroon. The lake’s isolation has resulted in the evolution of some unique fauna, including a handful of cichlids. Troy’s article gives a quick summary about the lake and the other cichlid species that call it home. However, the majority of the article is devoted to his experiences keeping and breeding Pungu maclareni. The article titled The Barombi Mbo Sponge Eater also has many great photos. To discuss P. maclareni or any of the other cichlid species from Lake Barombi Mbo, visit the Lake Victoria Basin, West African, Madagascar & Asian Species forum.

Gnathochromis permaxillaris is an unusual looking fish from Lake Tanganyika. Its most distinctive feature is the shape of its mouth. Living over the muddy lake bottom, the mouth acts like a vacuum cleaner to carefully lifts detritus and other organisms off the surface. While not very popular in the hobby, its feeding technique is interesting to watch. The video below shows how G. permaxillaris extends its mouth to feed off of the substrate. This species should not be kept with aggressive fish and should be provided a some type of cave for cover. To discuss Gnathochromis permaxillaris, visit the Lake Tanganyika forum. More pictures of G. permaxillaris can be seen on the Species Profile.

Happy holidays and a wonderful New Year from the Cichlid-Forum staff
The staff at Cichlid-Forum would like to wish everyone happy holidays. Please keep in mind that moderators and administrators will be busy traveling and spending time with their families, so we may not be able to get to things right away. Pictured abouve is the Xystichromis phytophagus or as they are commonly known, Christmas fulu. If you would like to learn more about this beautiful Victorian cichlid, visit the Species Article. For discussion on this and other Victorian species, make sure to check out the Lake Victoria basin forum.
Not a cichlid, not even a freshwater fish, but noteworthy nonetheless. A previously unknown species of Snailfish was captured on camera at a depth of almost 28,000 feet at the bottom of the Mariana Trench. The camera was part of a study to understand the ecosystems in the deepest parts of the ocean. The video below shows footage of the mysterious fish. Liparidae, commonly known as Snailfish, are composed of hundreds of different species. They all have scaleless, tadpole shaped bodies and not much is known about them. For more information on the discovery, visit NBCNews.com.
Julidochromis marksmithi, formally known as J. regani ‘Kipili’
It looks like the species we’ve known as Julidochromis regani ‘Kipili’ for so many years is getting an official description and a new name. In a recent article published in the Polish cichlid magazine Tanganika Magazyn, the new name for J. regani ‘Kipili’ is now Julidochromis marksmithi. For those who aren’t familiar with the genus Julidochromis, they are a species of rock dwelling cichlids from Lake Tanganyika. Julidochromis are pair-ponding egg-layers that mate for life. The bond between a pair is so strong, that the death of one fish usually results in the death of the other soon after. There is a short write-up on the article on the French Cichlid Association website. Discussions on Julidochromis can be found the the Lake Tanganyika Species forum.
At one time or another we’ve all experienced the frustration of having a sick cichlid. This is especially true for hobbyist who are new to the hobby. Fortunately, Cichlid-Forum has a couple of great resources for those looking to save their fish. The Illness, Health & Nutrition forum is where you can ask specific questions about your fish’s health. The forum’s moderators and members all contribute to help with specific health related questions.
If you are looking for more general information on fish diseases, including a detailed bloat cure procedure, the Health section of the library is the place to go. An ounce of prevention is worth a pound of cure couldn’t be more true when it comes to fish. Although it can happen, cichlids rarely get sick from other cichlids. Most of the time having a sick cichlid is the result of stress. A fish’s ability to fight off diseases is compromised when there is poor water quality, improper diet or a stressful environment. Making sure your fish are eating the proper food, breathing clean water and are comfortable in their surroundings is the best thing you can do for them. When that fails, the resources mentioned above are your best bet for turning things around.
