I have a South American tortoise (a Redfoot) that lives on sphagnum moss bedding. I have given some thought to switching her to a topsoil-based substrate, but I'm concerned that such a base will retain too much moisture.
Are there reptile-safe plants that I can add to the soil to maintain the right level of moisture as not to grow mold? Alternatively, are there other substrate materials that might make more sense in this environment? I like that the sphagnum moss dries out fairly effectively, but it would be nicer if the soil could retain the moisture and not crumble to bits over time.
