Looking for some help or insight. I have a hermanns tortoise we got in november of 2012 as a hatchling. Hes been with us and very well cared for & fed. Recently its started showing aggressive behavior. Whenever we reach in his enclosure he literally runs over as fast as it can & tries to bite us. Why or what is causing this?? He is well fed & cared for & never been mishandled. When all of sudden would it do this? Is it hormonal?? We only have one and dont know the sex of it either. Thanks for all help
