I have construction paper all around and just now even put it on the front so maybe he will stop hitting the front of the glass. I asked the prev owner about his behavior and she was shocked and swore he never did any of this with her but I kinda think she is lying because this snake seems like it was tortured or something he shakes really bad right before he comes at u with his mouth wide open I think maybe her kids tapped on his tank and aggravated him all the time maybe that is why he is so aggressive he will be one in july
