yeeyee

I have had a male leopard gecko for close to 8 years and he has occasionally been a little bit jumpy but usually had a typically calm leopard gecko behavior. Yesterday however, after handing him, placing him back into the tank and feeding him, he became ridiculously aggressive. He does not fear me and will do nothing if my hand is inside the tank and will readily accept food from hands like he always does, but if touched he will sqeak loudly, whirl around, and bite. strangely, he will follow this up by coming to the front of the glass and acting as if he is hungry when there is no food in sight. I am not sure what caused this change in behavior and it is very strange for a normally passive animal that has never bitten me before. He only becomes angry if touched or petted. there have been no changes to his enclosure whatsoever, and the same day as he aggressively bit me I handled him no problem. He is eating well and very greedy with food, otherwise healthy but I noticed he was walking slightly weird, so I started to dust his dubia a bit more just in case.
