Are you sure it's the same snake you were looking at before? I havent ever heard of Ben misrepresenting an animal for sale... If you have any doubts or questions, send him an email or a message on FB and get the real story before jumping to retun him. Also, give the snake a chance to settle in and try offering food in 5-7 days...

If he is that stressed, there may also be issues with the environment. Can you give us pics of your setup? What are the temps on hot and cool sides? Do you have hides?
