Answer
Hi Rene,
 I don't keep frontosa but I have several good friends that do and they always keep frontosa only with frontosa, i.e., they don't mix them with other fish.  Frontosa are rather strange cichlids -- they come from deep down in Lake Tanganyika and they don't do well with a lot of other fish in the tank.
