African Fat Tail Terrarium

[JHansson514]

I have a 75G tank that I'm going to use for a planted terrarium. It was intended for White's, but long story short that didn't work out, so now I am going to put my African Fat Tail, Walter, in there. I've made a background (I'll post pictures later) and I've got the material for a drainage layer. Are there any suggestions for good plants for a fat tail. Also, the current tank she is in has a heat mat (in addition to heat lights) and I wanted to use one in the new tank as well since she seems to love it, but with the drainage layer I'm thinking the heat wont even be felt. Any ideas?
