I still do not know if he is an extreme or not but he is 33 inches long right now. He is under a year old and the pet store only had him for 5 months and they bought him when he was very small. All they feed him was pinky mice and crickets. I have only recently been able to get him to eat grapes and bananas. Here are some pictures of his head. I just need to know if he is an extreme or not because I am going to build a bigger pen for him.
