Hi,
Cute Beardie...
Is that a heat or Uvb?
I would get a bigger tank in time, and I never use carpet...just good old news paper or paper towel works the best. I dont like nasty bacteria.
He also needs a bowl large enough to soak in..they like soaking especially when larger. I would get him a small cat litter box and fill it 1/2 way up. They LOVE it!
