I would think the lab would have more of a chance in the community tank. If its only 3inches your other fish should be safe for a while. Like coler said, Labs are pretty mild mannered.
I am just amazed by the way they act toward each other!
I even saw Oscar rub up against the Lab!:huh:
I know the situation can take a turn for the worst at any moment, but for now I really think Oscar has found himself a buddy!![]()
you could always get a divider.
