That is good to hear then, he tends to not ingest the substrate. Sometimes loose substrates,
depending on what they are can work & other times they don't. Each dragon is different so
you have to find what works well for him.
Let us know how the vet visit goes!
Can you post a coulpe pics of him just being him? I have only seen them in reptile stores a couple times and never outside of a reptile store. I think they are very pretty animals.
