I am setting up my first lizard home. I found a substrate that is ground up walnut shells. Of course the package says digestable and that it's better than sand, I have read other posts and done some research and I know not to blindly beleive those statements. I do prefer a natural looking tank, so I wouldn't lean toward astroturf or liners or paper towels, purely for aestetic reasons. However if those choices are the best for the reptiles then I would choose one of them. My Geckos will be a part of the family and their home (a 29 gallon tank) will be out in the family room. I wondering if anyone has any opinions on this.
