I'm thinking about getting a WTF soon. I have the Exo Terra 18 x 18 x 24. I'm looking for the ultimate set-up for these guys. I have toads, fowlers & southern in a planted tank that's been up and running for almost 2 years, and going strong. I just don't know if WTF's do better in one of these or one with removable bottoms like moss or reptile carpet. Also on the care sheets it does not show the best humidity range for them. Input please. Thanks.
