Substrate for Pixie Frog

[madratter5]

I have searched and can't find a good answer to my question so maybe y'all can help. Can I use peat moss as a substrate for my pixie frogs? I use it for my tarantulas so I have plenty on hand but I am getting in a couple of frogs in a few days and need to know if I need to go get something else for them. I have had huge problems with mold from eco earth in the past so I'm not sure I want to use it for my frogs.

Never mind. Had time for a more thorough search after I got home from work.
