Bites toward the rear are definite breeding signs. I agree that the smaller is too young to breed with any kind of success yet. A breeding attempt by an aggressive male can be very stressful for a young female. Seperating them was the right thing to do. Keep her a little darker if possible. She may take a day or two to come back on food.
I'm having to seperate out my male motoro (have one male, three females) because of the same issue. I'll have his set up done by this weekend.
