Morning,
I have yet to have any problems feeding live and find it easier than F/T. Typically the feeding should not take too long depending on your snakes feeding response. Error on the side of caution and monitor his feeding and have some tongs on stand-by in case you feel the need to interject if he doesn't feed and the prey item is nippy.
I feed in my tubs. Ball Pythons stress easily and taking them out and setting them in a separate tank can cause them to not eat or have a poor feeding response. In my collection I have seen no negative impact in the snake aggressiveness due to feeding in their tubs.
Happy Feeding!
