So, my Versicolor started exploring the bottom of the enclosure like he was looking for something. I captured some pictures of him hanging around a stump in the cage. Later when I returned, I noticed he was lethargic and maybe even going into a death curl. I added a water dish after misting the cage. He made a straight line for it and currently is getting a nice big drink. Hopefully he'll be ok. The substrate is vermiculite. Here's the pics.
