Hi, I've had my gecko now for 6 years when I bought him he was an adult so I don't know his true age. He's always been very tame would let anyone hold him, hand feed him etc. I have a 10 month old baby now and while I was pregnant I didn't handle him quite as much nor do I now, but lately I've been trying to hold him and he runs from me and opens his mouth like he's going to scream but he's never done that before. So I've been putting my hand in his tank to see if he would acknowledge me, he walks up to my hand licks it then walks off. Today I noticied shed stuck to one foot and tried to pick him up to soak him he twisted frantically then bit me, so I let him go thinking he'd drop his tail if I didn't. I then noticed he brought blood so I went and cleaned my hand. Why all of a sudden is he so aggressive is it because I didn't hold him as much while pregnant am I going to have to re-socialize him, or could something be wrong.
