I do have Nutribac. I posted on the elaphe schrenckii FB board and was advised trying live in 5 days, so that's what I'll try next with the Nutribac. Temps are perfect and he looks healthy otherwise. No signs of external parasites, no changes to enclosure, no obvious signs of shed yet - but it could be coming.

I have an exotic vet in town and that will be my next resort if he refuses live, I just worry about stressing him too much. Not sure how long such a tiny little thing can go without eating. Dec. 13 was his last consumed meal. I think because he was such a voracious eater before, and they are known for being such great eaters, the no-eating thing is really upsetting me. But I'm trying to be patient. I just worry about him being so young and small at only 13.7 grams. I would be so devastated if something happened to him.
