Well I used to have 2 cichlid tanks before going with SW. I will tell you even angelfish can be a problem in a community tank. They always suggest adding the angels last because if you add them first and then add other fish they become aggressive over territory. Cichlids are amazing and second best to saltwater but cichlids are territorial and very aggressive. You can't even mix all cichlids. You should not mix african with south american. I did but only the less aggressive types. In one tank I watched 2 cichlids slowly yet aggressively batter another cichlid to death. The next morning it was floating and when cichlids breed..watch out.
If you go with cichlids you should definitely read on the different ones, temprament and compatability. You can't put any regular cichlid with convicts, they'll kill them. If you put a demasoni with a frontosa well the demasoni stays around 2 inches and the fronts dinner.

In a short story, I would never mix any other tropical fish with cichlids besides angelfish. Cichlids will eventually kill plecos and even loaches.
