I've had my baby for about a month and he seems to be getting more used to me, but I have a lot of trouble getting him out of his tank. Once I get him out he is usually fine and calms down but he still tries to squirm. I always put my hand in front of him where he can see it and I pick him up gently.. but he always tries to run away and sometimes he even tries to jump out of the tank and it really scares me. Is this normal and will he ever calm down???
