First of all Linda G. I don't appreciate you talking to me like an idiot. If you have bother to ask me old or big she is than you would know that the tank I have her in is fine for her size. And for you info this not my first reptile. I have taking care of almost very reptile under the sun and have plenty of experience with them. If you don't want to offer me any suggestions than don't comment back to this posting.
