wish new snakes...don't handle them for a week or two after you get them...make sure they eat once or twice before starting to handle them...
he probably is stressed now, getting used to a new place...so not handling him will make him less nervous...
if he stays in a hidebox, it doesn't always means he's stressed...it's just more comfortable in there...mine are usually in their hideboxes and sometimes come out at night...
you'll learn to read your snake more once you've had him for a while...my bps are really sweet...then I have a little cornsnake that's pretty nervous...lot of animals...if you want to see I have most up at
www.hatchingherps.bravehost.com
I don't know how to do a signature here and writing out my list of animals each time would just take too long...
good luck, Rachel
