Does anyone here have experience with a loose substrate mix that their gecko can dig/comfortably live in? I've decided that my first few pay checks this summer will go to upgrading my leo's set up, I would love to get her off of her paper towel. I've asked around on the tumblr community, the users I usually consult on gecko care, and they all encouraged a certain mix:
4 parts Zoo Med Excavator clay, 3 parts sand, 1 part Exo Terra Riverbed sand (finer grain), and 2 parts organic potting soil.
It seems pretty well praised and I would like to try a more natural substrate. Does anybody here have any vivariums with these sorts of substrates?
