Well, sounds like he just doesn't want you to take his food away. I would feed him in his enclosure though, if your scared to pick him up. When they smell their food they are going to be in a defensive bite position.
I would just get some gloves and do it that way. You could also just throw a towel over him and pick him up that way. He thinks your trying to take his food (it's happened to my bf before). So, if you pull away everytime he strikes, it gives him a reason to strike again.
Once you get bit you will realize it doesn't hurt. I was scared until i was tagged for the first time. lol.
