ATBs will bite, musk and pee when they want to be left alone, which is most of the time. haha
I love them but treat them as a display snake. I have some that will tolerate some handling but even those, after 15-20 min will want to go back home and let you know it.
edit to add - they are heat seekers and will readily strike at something so simple as warm breath.
They are awesome!
