I'd just like to start off by saying that I wrote all this out of my memory, with no or very little reference to any sources. I will use one source rarely during my Post, Cichlids By David Alderton. I am hoping for this to be a general source of Information people can go to if they have a quick question about cichlids and don't need to write a post about it. Feel free to reply to this if you think there is something I missed or if you just want to voice your opinion about this thread.

General Info-Cichlids come from many parts of the world: Central America, South America, Africa, and Asia. There are many species of cichlids, which I will get to later on.

Tank Requirements-Generally for cichlids, a large tank with lots of space is required. This is not necessarily true for dwarf cichlids, a class of small cichlids, which still may need more space than a tetra of the same size. Some people say you can keep an oscar in a ten gallon, because it will only get as big as its environment allows. I disagree, because at the same time you are stunting its growth and depriving it of space it would normally have in the wild. My point is that just because a fish can fit in a tank , doesn't mean it should live in it.
A general rule in keeping cichlids is do not mix fish from different regions. Very rarely could you successfully keep fish from South America with fish from Africa. That is just one example showing not to mix fish from different parts of the world. As you could expect, since cichlids come from different parts of the world, they have different requirements which is why I will now organize this post by the different classes of fish. There are too few fish from asia for me to make a section about them.

Central American Cichlids- Some Central American cichlids include Jack Dempsey, Red Devil, Midas Cichlid, Firemouth cichlid, Convict cichlid, Blue acara, and Nicaraguan cichlid. Central American cichlids require a moderately large tank, upwards of 40 gallons depending on the species, but some small central american cichlids can be kept in a relatively smaller tank, such as convicts and friremouths. They generally need a pH ranging from neutral (7.0) to alkaline (7.8). The temperature range of Central American cichlids is from about 68 to 82 degrees farenheit. These fish will uproot/ destroy any plants you have in their aquarium.
Breeding is most of the time fairly easy with these fish, but can cause problems with their aggressive behavior during spawning time. To encourage spawning, fatten up the fish and seperate them so they can see each other, but cant touch each other (tank divider). then take out the dividr and most of the time, they will breed. During breeding, note that they should have the tank to themselves to prevent dead tankmates or eaten eggs. you should remove the father after the fertilization of the eggs to prevent the female from eating them. These fish generally produce between 50 and 300 eggs.

South American cichlids-Some South American cichlids include Angelfish, Discus, Ram, Oscar, Severum, and Green Terror. There peaceful South American cichlids and aggressive ones. The peaceful ones include angelfish, discus, and rams. The aggressive ones are pretty much any other ones. They generally need a soft pH ranging from acidic (6.3) to neutral (7.0). South American cichlids need high temperatures ranging from 77 to 82 degrees farenheit.
The peaceful ones should be seperated from the aggressive ones. The peaceful ones like plants and can go in a community tank, while the aggressive ones will uproot plants and will eat any fish that will fit in its mouth. The aggressive ones require a very large tank, upwards of 50 gallons, depending on the quantity.
Breeding of South American cichlids is very similar to Central American cichlids. They are very aggressive when breeding and should be alone. these fish can lay up to 2,500 eggs. Angelfish, discus, and rams most likely lay their eggs on a broad leaf, or a piece of slate. Amazon sword plants are highly recommended when keeping the peaceful ones.

African Cichlids-Some african cichlids include Julies, Brevis, Duboisi, Kribensis, Jewel Cichlid, Lemon Cichlid, Tropheops, Frontosa, Peacock Cichlids, Yellow Labs, Cobalt Blues, and Red Zebra Cichlids. Most African cichlids come from the west coast of africa or one of the three largest Rift valley lakes. Each group has completely different characteristics.The general pH toleration is high , from neutral to 7.8. They like high temperatures.
The main group is mbuna, which means "rock dwellers". These fish come from lake malawi. They include cobalt blues, red zebras, peacocks, yellow labs and many others. They need many rocks in heir aquarium and will most likely uproot any plants. These fish are herbivores and most likely will do nothing more than chase or beat up fish. They are very colorful, and with the exception of peacocks, breed unusually. The famale lays the eggs, then picks them up in her mouth. Males have spots on their anal fins called "egg spots" which they use for fertilization purposes. Females then keep the eggs in their mouths for about 3 weeks, until fry are free swimming.
The second group is from lake Tanganyika, which mainly consists of "shell dwellers", small fish that seek shelter in empty snail shells. The most popular fish from this lake is the Frontosa, a large colorful fish in which males get very large bumps on their heads when mature. They grow very slowly and although they look aggressive, they would be likely to not harm their tankmates. These fish need shells, (shelldwellers, not frontosa) or small places to hide that resemble shells. They also breed in shells. Tanganyikan cichlids are very colorful and some could live in a community tank, or with fish from the other two lakes.
The third group is Lake Victoria. many species of cichlids come from Lake Victoria, including Haplochromines, a large growing class of cichlids with huge lips. Fish from lake Victoria should have very hard water, because the water of Lake Victoria contains many dissolved minerals. Their pH should be kept between 7.2 and 8.3. They like the temperature of the tank to be between 72 and 78 degrees.

I guess I can be called more of a purest when it comes to cichlids. And being such, I think it's almost impossible to write a 'general' article to cover all the cichlids. Heck, it's difficult to write a general article for just one area.

You say not to mix cichlids from different habitats but you don't really come out and say why. Some riverine species of cichlids in Africa come from a lower pH, so therefore could some of these not be kept with South American cichlids if the pH requirements are met? Same goes for Centeral American and some Rift Lake Species.

You also state that they need a big tank.Why? Why does my 4 inch mbuna need a 40 gallon tank? You need to give more specifics as to why someone wouldn't want to do this.

Central American Cichlids- Some Central American cichlids include Jack Dempsey, Red Devil, Midas Cichlid, Firemouth cichlid, Convict cichlid, Blue acara, and Nicaraguan cichlid. Central American cichlids require a moderately large tank, upwards of 40 gallons depending on the species, but some small central american cichlids can be kept in a relatively smaller tank, such as convicts and friremouths.

Angelfish, discus, and rams most likely lay their eggs on a broad leaf, or a piece of slate. Amazon sword plants are highly recommended when keeping the peaceful ones.
Again touching on why fish from the different biotopes shouldn't be mixed: If CA can tolorate a pH of 7.0, and SA can tolorate a pH of 7.0, then shouldn't this make for a good tank?
African Cichlids-Some african cichlids include Julies, Brevis, Duboisi, Kribensis, Jewel Cichlid, Lemon Cichlid, Tropheops, Frontosa, Peacock Cichlids, Yellow Labs, Cobalt Blues, and Red Zebra Cichlids. Most African cichlids come from the west coast of africa or one of the three largest Rift valley lakes. Each group has completely different characteristics.The general pH toleration is high , from neutral to 7.8. They like high temperatures.
A ph of 7.8 would be minimum for most of the rift lakes, not max. Agian what about the riverine species that come from a lower pH?
The main group is mbuna, which means "rock dwellers". These fish come from lake malawi. They include cobalt blues, red zebras, peacocks, yellow labs and many others. They need many rocks in heir aquarium and will most likely uproot any plants. These fish are herbivores and most likely will do nothing more than chase or beat up fish.

Males have spots on their anal fins called "egg spots" which they use for fertilization purposes. Females then keep the eggs in their mouths for about 3 weeks, until fry are free swimming.
You say that they need rocks, and hint that they are rather aggresive to any and all other fish. But why? Once someone has a better understanding of why a fish acts as it does, then they will be able to prepare and give the fish a better place to live. Also peacocks are not mbuna. Males aren't the only ones to have eggspots, so this is a very unreliable way to sex the fish.
The second group is from lake Tanganyika, which mainly consists of "shell dwellers", small fish that seek shelter in empty snail shells. The most popular fish from this lake is the Frontosa, a large colorful fish in which males get very large bumps on their heads when mature. They grow very slowly and although they look aggressive, they would be likely to not harm their tankmates. These fish need shells, (shelldwellers, not frontosa) or small places to hide that resemble shells. They also breed in shells. Tanganyikan cichlids are very colorful and some could live in a community tank, or with fish from the other two lakes.
I would be hard pressed into beliveing that the shellies make up the majority of cichlids in Tanganyika. Saying that the frontosa is the most popular fish is an opinion. While the fronts are truely not very aggressive to cichlid standards, they will certianly harm other fish in the tank if it can fit into it's mouth. They are piscivores, or there main food source is other fish.
Color from a fish from Lake Tanganyika is few and far between. But for the most part the fish are drab.
The third group is Lake Victoria. many species of cichlids come from Lake Victoria, including Haplochromines, a large growing class of cichlids with huge lips. Fish from lake Victoria should have very hard water, because the water of Lake Victoria contains many dissolved minerals. Their pH should be kept between 7.2 and 8.3. They like the temperature of the tank to be between 72 and 78 degrees.

If I were reading this and knew nothing of cichlids I belive that this would raise more questions for me than give answers. You touch on several good points, and good ideas, but you don't go into any real detail about why. To give enough detail over everything to help a reader get a better understanding would make for a very lenghty article. This is why I said that a 'general cichlid' article is difficult to do.


There are also several spots where the focus jumps around making it difficult to follow.If you were to reorganize your thoughts and kept them togeather it would read much better IMO and be easier to understand.
