Hello, I am in the process of acquiring a leopard gecko, and before I receive the gecko I want to make sure that I am ready- meaning the tank is all set up and ready to go. I have heard a lot about tile as a substrate and how it is low maintenance and better for the gecko. I was just wondering where to get this tile and around how much does it cost to purchase this? And is it okay to use reptile carpet until I get tile if I am not able to get it before my gecko? Other than tile what is the best substrate, as is safest, to use?
