I upgraded my pair of box turtles to a 40 gallon breeder yesterday, and they love their new enclosure. I used decorative "live" sheet moss for some covered areas in the tank. And my female turtle loves it because it retains moisture so well and stays cool when in the shade. I am wondering if I can incorporate it in my tarantula enclosures. Its very pretty and claims to be organic (from what I understand its just dried sphagnum moss in connected sheets) but the bag it comes in is very ambiguous as to how it is prepared. The bag just talks about how it can be used for pot covers and such. It was in the organic section and it doesn't smell or feel harmful. But I was wondering if anyone else had used this material in arthropod enclosures before.
