I didn't say they lived on sand in their natural environment...I said they instinctively ate substrate to keep their calcium levels up. I do a lot of reading and thought that this was an interesting thing for them to do.

Ok...I didn't know that. I don't use the stuff myself. I guess the product is highly misleading. I just thought if he had his heart set on sand, this would be the lesser of two evils based on product claims.

Yes, it is walnut shells. It's ground fine enough that it isn't sharp, otherwise I wouldn't use it. But, like I said, I religeously provide calcium/vitamins/minerals and have never seen any of my leos eating it. They seem to really enjoy digging in it and laying in it too. LOL!

That does sound beautiful!
