I took him out and checked him over, no mites. None in the water none on him, he looks clean. The humidity is usually between 50-60%, it is at 62% right now but he pooped over night and it usually goes up when he does that by 5-10%.

When I put him back in his enclosure he slithered around for a minute and then proceeded to his cool side hide. I'm thinking he just wanted to be in the water, maybe he was feeling a little dehydrated.

Another quick question on mites though. Where do they come from and how could a snake get them?

Thanks
