Leopard geckos are terrestrial animals, which means they do most of their activities on the ground. That includes eating. It may be nifty to have colored sand or stones in your lizard's tank, but make sure he isn't accidentally ingesting bits of this substrate when he eats. Or use a nutritious substrate such as Calci-Sand which is less harmful to ingest. Geckos can impact (get their stomachs blocked up) from eating bits of sand, dirt, leaves, rocks, etc, that are too hard for them to pass or digest.
