WOW he's stunning!

On to the topic at hand, leave him be; he needs to adjust and you constantly checking up on him is more then likely stressing him out. I know it's hard to contain yourself when you get a new snake (especially one so friggin' pretty) but let him adjust before bothering him too much.

My spider male was the exact same way when I got him and he is still on the shy side after giving him all the time in the world to adjust. Some are just shy I guess, but again, just give him a little bit of time.
