you could but i heard that reptivite special sand is the best because it has calcium in it if ur beardie digests it and it doesnt clump together so ur beardie will be safe if it accidentilly eats it. if u dont trust sand u can use tile flooring< newspaper (i hate newspaper), papertowel (looks dirty and gets very dirty)< or artificial turf. ive heard a lot of mixed thought for the artificial turf though. i use the sand for some of my reptiles and nothing has ever happened to them
Have you tried Vermiculite or Perlite for substrate? the beauty of this, is when they poop, you can just scoop it up. I think you find with coconut husks, if your beardy dont eat all the crickets/locust ect, they can hide well down beneath it. I tried sand and it was just to messy, but the vermiculite is great for cleaning and it looks nice as well.
