Well I'll pull the blanket off and only speak from my experience. I had a pair of red devils Lived happily in a heavily stocked 180g tank with many different species of cichlids and some other fish. The RDs were eventually moved to a 450g tank where they spawned, I then had to remove the RDs to keep them from killing everything else in the tank.
Moral of the story is, ya just don't know and have to try different plausible possibilities out. Of coarse none of this will happen until you actually have the tank.
