It all depends. If they start showing signs of agression then you must seperate them. Some turtles really get along with one another very well. You will have to see what happens.
m & Z -- Tank size is key. If turtles have plenty of space they are less incline to be aggressive. She needs her corner and she needs hers. When they are bunched together there is more of a tendency to be aggressive. She or he, they need their own space; a place to hide or sleep. In some cases they can get along stacked on top of each other in others they will bite a foot, tail or anything else that get in their way.
