Not, I feed all of mine in their tubs and have no aggression at all. When you have more than 1 its too hard to take each one out and feed in a seperate tank. Alot easier to just feed in their tubs. Plus why stress out the snake by moving it before and after feeding! Also I have found that feeding in a seperate tank will get me bit more than in their tubs due to the fact they are in feeding mode when I go to get them back out.
