Why did I wake up to my snake soaking in his bowl?

Sometimes my snakes will soak in their dish if they are about to shed. It happens. If there are no mites present then I wouldn't worry about it.

No, I saw he was in the bowl early and left him. Gave him about an hour and he was still in there. I opened the tub and he came out and went into his hide. No signs of mites on any of the snakes. There are seven in the rack currently and he was the only one doing this. All temps where they should be and so is humidity. I use digital gauges and a temp gun. Temps in the tub are between 78-80 on cool side all the time. Hot spot is at 91.5. No mites on the snake or left in the water. He has never done this but two things have changes in the past month for him. One, he is the one ball python that has always had a bad attitude, so my daughter has worked hard the past few weeks trying to calm him down, so he has been handled a bit more than normal. We also just decided to give him a larger bowl last weekend. Could handling him more often has caused some stress and he decided to hide in his water? Seems weird to me. Maybe he just figured he can fit in the bowl again. I am just confused that he did that. I guess it will be just keep an eye on him.
