Well first of all hatchlings should be fed frequently...juveniles & adults you can feed 'em every 6 or 7 days...you might get him overweight...Your ball python might have feel threatend when you reach for the hide & probably that's why it tagged you...ball pythons might seem like if they're on the striking position but aren't gonna do a thing sometimes...try covering the tank with a towel or someting for a week or so & then watch its behavior...
