So for the past couple of feedings (I would say from 6-7) my boyfriend has fed our BP in its tank, which I specifically told him NOT to do because if in the event one of us needs to clean the tank and get our hands in there to handle him, then he's going to strike at us. Well, guess what. Our BP is now slightly aggressive, and will typically strike at anything that happens to come on the other side of his tank or even near the front of the glass.

By saying this, is there any way to reverse this aggressiveness to make him calm and cool again? My relatives were telling me that feeding him frozen mice/rats instead of live in his tank should be able to make him more docile again, but will that work?
