I just went today 01/05/08, to the White plains reptile expo. after looking around for a while I found 2 nice rough green snakes. I bought 1 for $15. first it was calm, and like an hour later it started opening its mouth really wide and bit at the plastic on the microwave container he was in. he tried biting my finger. then I took him home. he kept dtriking the glass in the tank, he wont calm down. please tell me what to do, someone.. thank you.
