Hey Wyatt.
I bought some of that pillow moss from the Reptile Expo I went to, and I've placed it in areas on top of my coco fiber (corners of the tank, near the water dish, etc) and I just water it from time to time and it seems to be doing well.
I did have a piece on top of one of the hides for a while but ended up moving it to a place where more soil was for it to settle into.
If that helps.
