Hi All! My husband and I are in the process of researching and setting up space for a leopard gecko. In our research there is a TON of debate regarding what is best and safe. Without starting a substrate war here, any advice for new newbies on what is best and why? We have some lightly textured tile to put down. However, we are not sure as far as sand, clay, bark, etc. what is safest and most natural for the gecko. HELP!
