There's not a higher demand for them 'cause not a lot of people have exotic pets, or if they do, they hardly take them in. Wouldn't bring in enough money to have an exotic vet. At least that's how they see it. Good luck to you though! And I love what you've done with everything! ^^
I'm sorry, but I don't see your uvb light anywhere in those pics. Am I just missing it? lol From what I was told, your beardies need to be able to get about 8"-10" from the uvb. Hope this helps!
