Yeah, that sounds about how I have them set up. They are basking on flat limestone at 100-105, and the substrate is organic potting soil/sand. They have a cave under the basking spot and I plan to add a few more, but they seem to like to burrow like my fire skinks. They are starting to acclimate pretty well, ie, not bolting the second they hear or see me. 
I hope to breed them.
