I've got a Squirrel Tree Frog who I've had for a month now. So far he's been kept on Eco-Earth bedding and now needs a change. I went to the store and they didn't have any so I picked up some Exo Terra Forest Moss. It says it's for frogs, lizards, ect and even features a Pac Man (I believe) frog and a Poison Dart Frog on the front.

I just want to make sure this is an ok brand of moss to use for my little guy before I add it. Even though it says it's for frogs, I want to be sure I can trust it. (Since cedar and pine shavings are often sold for things like ferrets, rats, hamsters, ect and will lead to nothing but health problems, even possibly death when used.)

How often should I change the bedding? It's a 20 gallon long (I know, a taller one would be better but I had this one already before I ever got my frog and can't afford $100 new tank) and only has one adult STF in it.
