Are you sure he is 6months old? I know every animal is different but 181g seems aweful small for a 6mo ball python. My guy is I figure around 6 or 7 months and he weight 350g. I feed him on a 7 day schedule and he is usually out cruising at night a few days before eating. I have no doubt he would eat more frequently but that doesn't mean he should. Your prey size sound about right for his size.
