Hi, I'm getting a bearded dragon on sunday. I have a very important question on substrate. I'm probably going to be getting a young dragon around maybe 4 inches. The substrate I have now is desert blend. It's crushed wallnutshells. Is this a good substrate for a young bearded dragon? Also, I heard that childrens play sand is good too. But i'm really concerned about impaction. Thanks alot.
Mike.
