Live plants :
I'd be very worried the dragon will nibble or even lick those plants.
I STRONGLY ADVISE REMOVING THEM and checking if they are SAFE if licked or eaten .
Stones and gravel = VERY DANGEROUS :
Impaction risk. I STRONGLY ADVISE REMOVING THEM .
Here are some current photos. I changed the rock so only large rocks are on the surface. This has prevented them from eating any rocks. The plants are all edible aloe plants, they have been snacking on them without any issues.
