so I am now monitoring his temp in two places in the tank, bought a new giant mister, and making sure his tank humidity and temp are exactly where they should be. Tonight I gave him a soak and changed his substrate. He does not seem to be going into aestivation any more, but he has not regained his appetite. He is still pretty fat but he has only eaten one nightcrawler in the past week and a half. He has not pooped in three weeks or so, but has not been eating much in the time. No lumps in his belly. He was chirping yesterday which I think is generally a good sign. Should I go to the vet? I get crazy ideas in my head like his substrate might have been contaminated, which is why i changed it even though I changed it less than a month ago.
