I guess I would love an all Cichla tank. I have one but it's just the 55g until the lil guy's grow out. I don't see anything wrong with all P's in the tank. Can't wait to see what you come up with Shamrock.
I think I will stay with my original plan-but I do agree that anything under 12 inches is liable to get eaten! What do you guys think about an Emperor Cichlid?
