I have a flag fish in a 29 gallon tank. I basically use the tank as a storage/grow out tank. The flag fish has never bothered any of the apistos that have been in there. Right now I have some 9 week old fry in the tank to grow out and the flag fish basically ignores them. As for Apistos being aggressive, I must be lucky because I have never had a problem. For example, right now I have a 37 gallon planted tank with lots of rocks and the following cichlids in it: 1 female A. hoignei 1 female A. agassizii "Triple Red"(who just spawned today!) 1 female A. sp. "Breitbinden" 1 male A. agassizii "Blue/Yellow" 1 male A. cacatuoides "Orange Flash" 4 Blue Rams (3 male and 1 female, I think) 2 pair of A. bitaeniata I have a few more fish in there than I would like but I had to put them in due to some tank switching and spawning happening and such. Anyway, I have no problem with aggression. Every once in a while some one will chase another for a short distance, but that is it. No one even has any torn fins! Maybe it is because I have so many different types, the aggression is spread out? As some one before mentioned, it probably has a lot to do with the individuals and the environment. The only problem I have had is that I have a male A. sp. "Papagei" that will kill any new dither fish I add into the tank. The ones that were there before he was, he leaves alone, if I add any new pencil fish or hatchet fish, he kills the newcomer. Just my two cents, and a little bit of the other side of the story...
