I am trying to set up a nice tank for some potential geckos, no real time limit.
I see sand-yes and sand-no, though there seems to be an age/time-limit (older is better for sand?). I am pondering this;
rocks. As a geologist, I have access to a LOT of rocks, all of which I could easily bake to kill anything that may be in there. Is there a reason I couldn't build a happy leopard land out of pieces of solid, textured rock? Hideys, one special egg hidey with wet substrate for the females, but any reason I can't just find some nice sandstones, slates, maybe something with fossils in it, and just clean them? Sounds more visually pleasing to me than paper towels
