You'll probably just have to wait and find out. My guess will be that they'll battle it out. It'll only be a border dispute though, I don't imagine one will wipe out the other. What I do in these cases is, when they eventually start going at it, to use a syringe with some hot water and make a DMZ between them. They won't kill each other and they'll keep owing in other directions.
