Just fed him his first Horn Worm. He LOVED it. Nom nom nom.
He has a water dish, and a food dish. There IS commercial food in it in the picture, but that was my girlfriend's idea. -_- Just in case he got hungry at night or something.
I gave him his first bath a few nights ago. He LOVED it.
If I were you, I would take out that sand. It may cause impaction if he ingests some, its bad on their lungs, and it could get in his eyes. As an alternative I would recommend slate tile and reptile carpet.
I agree about sand. You could use tile, repti carpet, paper towels or newspaper as an alternative.
Cute little dragon! And welcome to the site where there are no stupid questions.
