As many have said above - all of this does kinda depend on the size of your actual tank.
I've had my O's kill each other. Even ones that had grown up together.
So... just keep an eye on the situation but unless your tank is big enough to sustain them both you are much better off taking one back. Trust me, at those sizes the last thing you want to do is find it dead at the bottom of your tank... its just depressing.
