Finally upgraded his coil uvb to an Arcadia ProT5 12% 24 watt. And I added organic topsoil to his sand. I'm hoping he enjoys digging in this more. I also bought a hide for his cool side. It's actually for the small, furry types since it's made from Timothy hay, but he doesn't eat it, so it was cheaper than a reptile hide. The log hid is really too small for him, but he uses it to rub his pores on, so I will leave it till I build his final house.
The vet said he's in excellent health, no parasites, good weight and length. He didn't even get blackbeard when he was handled by someone other than me!
Anyway, Thor does not eat his substrate, and I now feed him from a glass dish with his worms, so he shouldn't ingest any dirt. The vet said his house is okay, just watch for changes, which I always do anyways.
Other than switching out is substrate, do you have any other suggestions or opinions? I'm going to start on his final habitat this fall. He will go from his current 4x2x2 to a 6x2x2.
