So, someone offered up an 8 mo. old bally in the paper (couldn't keep it, they had a 4 mo. old kid...you do the math. Gotta love that forethought.) and I took him in. He came in a 10g, no hides but a fake plant, most of his space taken up with a basking branch, and a weak lamp with no UTH. I gave him a UTH immediately (along with a thermometer) and after letting him chill a couple days, two hides, with some moist papertowels to up his humidity (his skin's a little wrinkly). He's also underweight, and though they claim he was on f/t, hasn't eaten yet in three or so attempts. He came home on the 4th, so I'm not quite panicked yet, but it's still bugging me he won't eat. I haven't vetted him yet, since I like to get snakes eating before I do anything stressful to them, but at least to my observations he's got no mouthrot or obvious disease, but he's pretty underweight, almost triangular at this point, as he's never been fed on anything above pinkies apparently. Temps are 93ish on the warm end and usually 82ish on the cool, I've been letting temps drop at night just in case he's not used to having two heat sources yet (probably unnecessary, but I like to make changes slowly) and the ambient humidity's usually around 50 though I had it bumped up for the first week or so.

I'm pretty new to ballies so I'm not sure at what point I should really begin to worry and take him to the vet for force-feeding. Is it that time yet, or do I still have some chances to find out what, if anything, works? They said he eats in the cage, on paper, so I've been trying variations on that, but I'm about to try putting him in a nice opaque deli cup overnight, then a live pink, etc since nothing so far has worked. I'm waiting 5-6 days in between trials, is he safe enough that I could just leave him alone 10 days or so and try again?

Basically I just want to know whether I should be worried yet. Though suggestions are wonderful too!
