Temp runs about 72-74 degrees. Yes, I mist him daily. I've never used substrate. I'm kind of scared he'll get it in his mouth and choke on it.

Now, I saw something at work that would work wonderfully under my tank...in theory. We sell these little flat...planter heating things. Would that go over well with a 10 gallon tank or do I need something frog specific? (He's STILL shedding by the way. I put him someplace warmer and...nope. He's still at it.)

Where I used to live was VERY hot and humid. Then I moved to the cold. I've been here three years and this is the first winter he's had issues. It's also the first winter we've had very little snow.
