In the last few days my daughters corn snake has got very aggressive. Not sure what sex but it's pretty much adult about 4ft long. She tried taking him out of his T8 enclosure and it coiled up with head raised shaking it's tail like a rattlesnake. It has always been a great feeder and when I went to feed him last night I had f/t mouse on tongs like always he came charging out of his log and attacked the mouse then dropped it and sat over it coiled like a cobra shaking his tail all mean like. Just wired how he charged out like that with such an attitude, we've had him/her quite a while and it's never acted like that before.
