My male bee is awsome and love him to death. He eats like there is no tomorrow (he would eat everyday if he could). but I got two questions about him. Hes only 2 months or 3 months old. and

1. Everytime I open his tub I get bit atleast once lol, not that it matters to me (concidering that Hes tagged me a good 20 or more time by this point he always seems to do it when Im not looking) Is this bc i feed him in the tub, or is it just him being def.
2. When I put food in the tub I seem his head start to kinda vibrate back and forth (Ive been told they do this cause they get excited for food, is this true), but the aswell everytime he finish's the kill (he will only take live at the moment) he will stick his head in the air, Kinda like look at me Im the champ, and then proceed to feed.

Any answers to the questions would be Great thnx
