Your dragon is very cute. How old is he? I've heard they can have relocation stress after being in a new place and not want to eat right away. As far as him being scared to go on the floor, I'm not sure. I'm sure someone with more experience can give you advice on that. I don't have experience with this yet, as I am getting my first dragon next Tuesday. I can't wait! I've heard they can become addictive.
I do have a leopard gecko that I used to feed crickets to, and yes, they do smell - and that wasn't even the large amounts that I'll need for the dragon! Not really looking forward to that. The things we do for our babies, right?
Hope all goes well with your little one. Can't wait to post my introduction thread on Tuesday!
