HCA: Hermit Crab Association

So I recently ordered some snakeskin from online(seller specified that there were no medications given to snake). I was going to give it to them every once in a while since I don't have a lot, but can I just leave it in the tank like a cuttlebone? Or would it mold easily?

Hello Snake shed will not mold You can certainly leave it in the tank. I would just tear a small piece from it at a time
