Homopholis querys

[syfx]

I need some definate advice on how to house these properly, im currently keeping them on a scrubby desert type substrate of sand and bark mixed with a handful of stones, ground temp is around 90F (although they dont seem to seek the cooler areas) and im also heating the rear wall to around 84F

For decoration i am using hanging plants from the rockwall (2) a short spindly branch and a resin mini treestump as a hide on the warm side of the floor ( i use a small heatmatt (5'' x 10'' approx) to heat the floor closest to rock wall and the front of the tank is cooler..
i have also layed pieces of slate to create another two hides on the floor. (2 warm, one cooler in total)

I give the whole enclosure a few mists in the day. i try not to have running drips on the glass when i do this.

The rockwall is only heated for the bottom two thirds, the top third doesnt have any matt behind it.

How do other keepers house their Homopholis Fasiata. Im confused on their exact requirements.? Any photos would be greatly appreciated.

Forgot to add, they are in a 30 x 30 x 45 exoterra
