Wallace is probably not quite as bad as your guy was. He still bites the snake hook now and then, but I lather it up with hand sanitizer now and he seems to dislike that immensely.
I think he's primarily keyed for food and is just ready at any moment. If I could ever get him out of his perches I'd handle him more, but he's perched so frequently that I rarely get a chance to get him out.
I'm glad Gerald is doing well and kind of wish you still had him, but you ended up with a double whammy of bad retic experiences.
Enough is enough!
