I agree. Dont lower the humidity. Raise it to a more normal level. Also raise the temp. Some articles on care say up to 95 F for basking is good. A little lower at night. Heat bulbs- good but dont let the snake get burned. If you lower the humidity the snake will dehydrate quicker. Sick snakes/reptiles dont eat/drink regularly. You already have a sick snake- dont make it more ill. Antibiotics- definitely!!! Vet check- Definitely!!!! Get on it now or the snake probably wont live.
