Thanks for the response!

He seems to be doing a little better. I've been soaking him daily, and the texture of his skin looks noticeably better. His appetite is still pretty poor- although I've been offering mustard greens, turnip greens, dandelion, hibiscus and nasturtium. He's definitely more active though.

His lights had no UVB. I have him on a megaray bulb inside right now as well as about an hour a day of regular sunlight (unfiltered).

I'm getting a little attached to him, although my tortoise experience is zip (I have beardies and uros).
