I am currently taking care of a very interesting Leopard gecko. I've been trying to bond with him, as currently he will not allow me to touch him. I started by feeding him mealworms with my fingers, and he readily takes them. However, now whenever I stick my hand in, he lunges at me! I realized my mistake and started feeding him with my hand flat on the ground rather than with my thumb and pointer finger, but it hasn't changed how he lunges at my hand. I went to mist his humid hide and he jumped a couple inches trying to get to my fingers! I'm new to keeping reptiles, but to my understanding leopard geckos don't normally act like this! It's not painful to be bitten, but I'd like to get to hold him at some point, and this has been going on for quite a few months. What should I do?
