Sediment core samples have shown that in the last 150 years Lake Tanganyika’s water temperatures have been rising. This steady increase in water temperatures, not commercial fishing, has had the largest impact on fish populations in the lake. Rising water temperatures, particularly at the surface, have led to a drop in oxygen levels at all depths of the lake. For more information on the study check out the links above.

Commonly known as the African butterfly cichlid, Anomalochromis thomasi is found in small streams of Sierra Leone, Guinea and Liberia. Males can reach sizes of about 3 inches while females are slightly smaller. Their size makes them a great choice for anyone looking for a dwarf species or with limited tank space. A minimum of 20 gallons is recommended for a single pair. They are colorful, peaceful and fun to watch.
In the aquarium Anomalochromis thomasi are easy to maintain. Water requirements aren’t too strict and they aren’t fuzzy eaters. Once a pair forms, the female will lay eggs on a flat surface for the male to fertilize. The pair will then defend the area from other fish. Food high in protein is recommended to encourage spawning. For more information on this wonderful little cichlid visit the West African Species forum.
A short video in the waters around Nakantenga Island in Lake Malawi.
The video was taken just this year by Pam Chin. Pam is well known around the hobby. She is an Honorary Life Member of the Pacific Coast Cichlid Association and has served on the American Cichlid Association’s board. Pam was also one of the founding members of Babes in the Cichlid Hobby which raises money for cichlid conservation and research.
The video shows the abundance of cichlids that can be seen while out for a swim around Nakantenga Island in the southern part of Lake Malawi. Nakantenga is right next to another location known for a variety of cichlids in the hobby, Maleri Island. For more videos from Pam’s trip to Lake Malawi visit her YouTube Channel.

The rumors and speculation can finally be put to rest. Cichlids of Africa Volume II is finally out and a limited amount copies are available before full distribution is set up in the U.S. The book is available in Europe directly from one of the authors, Anton Lamboj. In the U.S., the book is available through another of the authors, Greg Steeves.
The original, Cichlids of Africa Volume I, covered many species that normally aren’t seen in cichlid publications. Specifically, Volume I was about cichlids from Lake Victoria and surrounding lakes. A review can be found HERE by Ken Boorman.
Cichlids of Africa Volume II also covers Lake Victoria region cichlids but also includes West African riverine cichlids. Both areas have beautiful, unique and out of the ordinary cichlids, but are underrepresented in print work. The authors, Greg Steeves, Anton Lamboj and Hans van Heusden have put together amazing information and photographs in this book. Hopefully we will have a full review posted in the library soon.

A great video showing a pair of Red Spotted Severum spawning. Video courtesy of Jim Cumming
The Red Spotted Severum is variant of Heros efasciatus, not a Heros severus. More specifically, the Red Spotted variant is a line bred Gold Severum for the red coloration. The different color variants differ from the wild-caught H. efasciatus, but are still the same species. The striking differences in color is very similar to what has been done with discus cichlids, where the wild species looks considerable different than the line-bred variants.
In the wild, Heros efasciatus can reach 12 inches in size. However, in an aquarium they don’t get that large (8″-10″). That being said, these fish can still get quite large and a pair is best kept in at least a 75 gallon tank. For breeding, it is recommended to get a group of these fish. As they mature, a pair will form. Breeding usually takes place on a flat surface. As seen in the video, the female will lay the eggs and the male then fertilizes them. Once the eggs hatch after a few days, the fry are usually moved to a small depression where both parents will guard them. For more information on Red Spotted Severum or any of the other variants, visit the South American Cichlids forum. Make sure to visit Jim Cumming’s Youtube channel for other great videos.
One of the larger species of Julidochromis from Lake Tanganyika is the Julidochromis regani. Although they are said to grow quite large in the wild, their maximum size is the aquarium is around 6 inches. The other Julidochromis species tend to spend all their time in and around rocks and caves, but J. regani is comfortable over sandy shallows in search of crustaceans and mollusks.
In the aquarium Julidochromis regani’s behavior is similar to the other species in the genus. Julidochromis will pair up as they mature and the bond usually lasts a lifetime. If one fish in the pair dies, it isn’t uncommon for the other fish to die shortly after. Despite the strong bond, stress and sudden changes in the tank environment can break up a pair. To form a pair it is best to introduce a group of juvenile fish into an aquarium. Once a pair forms, other fish should be removed as the pair will not tolerate other J. regani in the tank. To learn more about Julidochromis regani or Julidochromis in general visit the Lake Tanganyika Species forum.
The Great Lakes Aquarium in Duluth, MN just opened their newest exhibit. The Unsalted Seas exhibit is home to the largest sturgeon touch-tank in North America and also displays their African Rift Lakes tanks. The Amazing Amazon exhibit also has a variety of New World cichlids which make their home in the Amazon Basin. Another interesting and educational exhibit is the Aquatic Invaders section. It explains how invasive species make it into new waters and their impact on the local ecology.
The Great Lakes Aquarium is a 501(c)3 non-profit corporation serving the community and part of its mission is to inspire people to explore and connect with the waters of the world in a effort to value and protect them.

Paraneetroplus synspilus can be found in the Usumacinta River system of Southern Mexico, Belize and Guatemala. This fish can be found under several names, both scientific and common. They include Vieja and Cichlasoma synspila, redhead cichlid and quetzel cichlid.
In the aquarium Paraneetroplus synspilus can reach sizes in excess 12 inches. Males and females look similar, but males are usually larger. Large, mature males will develop a hump on their head. P. synspilus is a rather peaceful species but like many other fish, breeding brings out aggressive/territorial behavior. They can be kept with a variety of other large New World species. Breeding takes place on a flat rock and spawns result in hundreds of eggs. To discuss Paraneetroplus synspilus visit the Central American Cichlids forum.
Another species of cichlid that grow a hump on their head is Cyrtocara moorii from Lake Malawi. The nuchal hump is similar to that of the Cyphotilapia frontosa from the previous blog, but these fish have no relation and are an example of convergent evolution.
In the wild Cyrtocara moorii is widely distributed throughout Lake Malawi. They spend their time sifting the sandy bottom for food at about 10 to 50 feet in depth. Despite being found in many locations, C. moorii are rarely spotted. It was first imported in the late 1960′s and has been in the hobby ever since.
In the aquarium Cyrtocara moorii is a gentle giant. Rarely aggressive unless provoked or spawning. Care should be taken to ensure tankmates aren’t aggressive, especially if you are hoping for them to spawn. C. moorii is very slow growing but males will eventually reach 10+ inches. Females will be a few inches smaller. A large tank is a must for these fish and a sandy substrate is recommended to encourage natural feeding behaviors and spawning. For more information of this species check out the Species Article by Marc Elieson or visit the Lake Malawi Species forum.
