I was trying to get his dish out when he tried to bite me. So I used the spoon you see in the pic to try and get him out of the dish, as soon as i touched him he whipped around and snatched the spoon out of my hand and bit his own tail. All in one bite.
it seemed as though he thought he was biting another gecko, and being bit by another gecko. I tried to get him to release but he just bit harder. No matter how hard his tail was being bit he wasn't going to let that other gecko win. lol
