The problem is that one of my BTS associates my hand with food. Consequently, he keeps trying to bite my hands whenever I try to handle him, clean his enclosure, and, of course, feed him. I keep him in a large plastic container with a top. When I feed him with a bowl of mixed foods I have to lift the top off and place the bowl in the enclosure. The BTS always sees me do this, so now he's always trying to bite me as a result. He's also my most aggressive feeder. How can I break his habit and avoid it in the future?
