Can i keep a peacock bass,oscar and jaguar cichlid together?

tank is a 55 atm and all 3 fish are about 2 inches big, going to get a 125-240 soon depending on what i find, but im just wondering how they will do together when they get bigger, because atm they seemed to be doin fine with the occasional chanse by the jaguar.|||Yes, they should all be compatible. Just watch the growth patterns. They are all aggressive fish, and one will try to be the dominate fish (king of the hill syndrome). Oscars and the Jaguar are both members of the Cichlid family.
