Thank you Brian for your reply. By leaf litter do you mean just dried up leaves from outside? Sorry if I sound stupid but this is my first time having frogs. And yes they don't like the feel of the coconut fiber getting on them, thats why I put down the moss(and yes it is the stringy type) so the stringy type isn't good to have in their home?? Would it be better to get the clumpy kind from the pet store, as I seen they had that too.
