Chance (Red-tail BCI) is getting ready to shed.How do i keep my humidity up? Right now he is in a 10 gal, but tonight I am moving him to a 20 L w/ a screen top for now.

I really need help with humidity level.My husband is out buying a water bottle right now. I have a heating pad UNDER HALF the tank, and also have dome light on top of the cage.He has a half shape log for a hide and water dish.Right now, I have 2 water bowls.one is right under the light (hoping it will help raise the hum.?) and i also have a damp towel over the cool side.

what he looks like now
