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.

Cyphotilapia frontosa from Lake Tanganyika

Cyphotilapia frontosa are not the largest cichlids in Lake Tanganyika, but it is the largest species regularly collected from the lake. Reaching upwards of 16 inches, a tank full of adult C. frontosa is a site to see. As male C. frontosa mature they develop an impressive hump on their forehead.

In the aquarium Cyphotilapia frontosa need lots of room. They are best kept in groups and when mature a 6 foot tank is best. Sexing C. frontosa can be difficult and is best done by venting each fish. If you think you would like to invest the time, effort and expense of keeping this beautiful fish, check out the Frontosa Corner in the library for articles about proper care, sexing, feeding and even collecting. Discussion can be done in the Lake Tanganyika forum.

Sympatric speciation in Nicaraguan cichlids

Sympatric speciation happens when different species evolve from a common ancestor without any geographic barriers to separate them. Each new species still inhabits the same areas and can come in contact with each other. Because there are no geographic barriers keeping groups apart, this type of evolutionary process can be difficult due to inbreeding.

Researchers working in crater lakes in Nicaragua have published research article providing empirical evidence of sympatric speciation. Two closely related species of Central American cichlids, Amphilophus citrinellus and A. labiatus are given as examples of sympatric speciation. To read more about this research visit the article on the Public Library of Science website. A summary of the publication can be found on the ScienceDaily.com.

RIPPLE Africa protecting Lake Malawi fish

RIPPLE Africa is working to ensure the future of fish stocks in Lake Malawi. While preventing the depletion of fish species used for food they are also protecting cichlid species. As over-fishing has led to a reduction of catches by as much as 90%, many locals have resorted to larger nets with smaller mesh sizes. In many cases, mosquito nets are used along the shore. The result has been that smaller and smaller fish are being caught. The small mesh sizes are also catching unintended fish, like young cichlid fry.

RIPPLE Africa is working at the local level with community-run conservation committees which enforce local bylaws and even provide a 3-month no fishing season. More information on this initiative can be found on TheDailyMeal.com and on the RIPPLEAfrica.org website.

Google Earth and Maps get update

Google Earth and Maps has recently gotten an image resolution update. Along with the update the service has also made images available without cloud cover. While this isn’t exactly cichlid related, having the ability to see the locations where fish are collected in high resolution is worth taking a look. The higher resolution allows you to see the rock formations just below the surface as well as small fishing craft lined up along the coastlines. With the Google Earth application, user submitted images of locations can also be viewed to get a real appreciation of the area.

Neolamprologus sexfasciatus from Lake Tanganyika

Often called the six-barred Lamprologus or gold sexfasciatus, Neolamprologus sexfasciatus is one of those cichlids Lake Tanganyika enthusiasts often consider keeping. However, seeing and wanting a fish doesn’t always translate into owning them. Similar in appearance to Neolamprologus tretocephalus, N. sexfasciatus has the same shape and barring but with the added gold/yellow color. In the wild this species is aggressive and predatory, feeding on other fish.

In the aquarium Neolamprologus sexfasciatus can be difficult to keep and breed. Their aggression and dietary requirements make them incompatible with many species. Tanks should be at least 4 feet long with plenty of rocky cover for a single pair of N. sexfasciatus. Forming a breeding pair can be difficult. A male and female can’t be put together and expect them to get along, much less breed. Pairs should be formed by keeping a group of young N. sexfasciatus. If a male and female are compatible, they will pair up for breeding. Other N. sexfasciatus will not be tolerated. If a pair does breed by laying eggs in a cave, the male will become hyper-aggressive toward any fish. Once the fry are old enough to be on their own the pair will break up and the female will be a target of male aggression. If you are considering adding Neolamprologus sexfasciatus to one of your tanks visit the Lake Tanganyika Forum for more information.

Greg Steeves

Greg Steeves

The American Cichlid Association Convention 2016 is less than two weeks away. The speaker profiles leading up to the convention continue and today we cover Greg Steeves. For those who have an interest in cichlids from the Lake Victoria region the name should be familiar. Greg probably has one of the biggest Victorian collections in the Western Hemisphere. Greg has kept cichlids most of his life and large part of his fishroom is dedicated to Victorian cichlids. If there is an out of the ordinary Victoria on your must have list, Greg has or has had it at one time.

He has co-authored several books and his latest publication with Anton Lamboj and Hans van Heusden titled Cichlids of Africa – Haplochromines II is due out soon. You’ll find many articles written by Greg in various publications and in this site’s library. Greg also maintains AfricanCichlids.net and is proudly involved with the C.A.R.E.S. Preservation Program (site currently down). To meet Greg Steeves and the other great speakers make sure to attend the ACA Convention 2016.

Mchenga conophoros from Lake Malawi

Mchenga conophoros is another of the bower-building species of Lake Malawi. Males create bowers in order to attract females. Each species builds the same type of bowers, but the variation between species is considerable. In the case of M. conophorus, bowers are build in the shape of a cone on the sandy bottom at a depth of around 10 to 20 feet. M. conophorus feeds primarily on zooplankton found in open water.

In the aquarium Mchenga conophoros can be difficult to keep. When mature they require plenty of room, especially if you expect to see bower-building. Males can also be very intolerant of other males. Groups of a single males and multiple females are best. A protein based diet is best. To discuss M. conophorus and other bower-building cichlids visit the Lake Malawi Species forum.

Astatoreochromis alluaudi from Lake Victoria

Although generally thought of as a Lake Victoria species, Astatoreochromis alluaudi is found in many lakes, rivers and streams in the region. A. alluaudi, commonly known as Allauad’s Haplo, was first collected and named over a hundred years ago. It was somewhat common in the hobby a while back, but mostly disappear from the trade. Its current status is in wild is unknown but not believed to be under serious threat thanks to its wide distribution.

In the aquarium Astatoreochromis alluaudi is an interesting fish. Males are more colorful and larger than females. In pictures its size can be deceiving as they can reach over 7 inches in length. Despite aggression between males, A. alluaudi is mild-mannered toward other species. Its intense yellow coloration and size can be an excellent addition to a suitable aquarium. They will accept most foods and will rid tanks of unwanted snails. To discuss A. alluaudi visit the Lake Victoria Basin forum.
