You've not met my snakes. I have two that are quite bitey. One will bite even when held, the other only bites in the cage. But it does try to strike me on a regular basis through the glass! Most are mellow, I think these are not the norm with BPs. Out of 13 snakes (11 bp and 2 corn) they are my aggressive ones. I have a pair of leather gloves I put on plus a sweatshirt to cover my arm if I have to do anything inside the cages for them, not a big deal.
I agree that some more specific questions would be helpful. If you wanting to know what their like in the day time just put a stuffed animal in a tank. They move about the same during the day anywaysIf you are a late night or real early morning person you can catch them moving around. I usually wake up between 3-4 AM and catch the tail end of my snakes being active. They can be picky eaters at times. I love watching them eat though.
