Yeah, I agree. The thing with either species is it will depend on tank size and on the individual fish, so it's not 100% predictable. One thing you can't always do (with a lot of cichlids) is take what you're seeing from them in a bare lfs tank, often too small, or in which the fish may have only been living a very short time, and extrapolate from that to be sure what they'll do in your tank. The same sev that kills everything they put in with it in a small tank at the lfs can be a perfect citizen once you get it home to a more suitable tank (I've had it happen). The same shy little cichlid that doesn't bother the other fish at the lfs can turn into a psycho killer after growing a bit and feeling at home in your tank.
