Just spray down the tub 2-3x daily. You may just have too many holes in the tub. I would be mostly concerned with getting the temps right. Once your temps are right, give your new baby a week and then feed him. Once's he's eaten three time (even if that takes 2 months), then you can hold him. I know it's hard, but try to resist! Give him peace and try not to pester him. He may not have eaten those 8 weeks because he was kept in improper conditions. Hopefully he'll bounce right back for you! Once he starts eating, you can feed him every 5-7 days to get him back to a healthy weight. Also, be prepared, but he may not want to take frozen right away. You can try it, but also be on the lookout for who might offer live feeders in the case that you need to feed him live for a few feedings until you can switch him. Good luck! I rescued a very skinny ball python back in July (she was smaller than your guy) so if you have any questions, just let me know! My girl started out at 44g and is now 251g as of today!
