What goes under the Coco Hut ?

[whydoidothis]

I have mostly everything in the vivarium that I want in there, except for the frogs, and a coco hut. Right now its sitting on top of the dendro bedding substrate. Should I have something on top of the dendro substrate and underneath the Cocohut ? Moss maybe ? I'm just not sure how azureus like to set up in their home. I will try to take some pics today, if I can find my camera, and post them later. I have a couple other questions, but the pics will help in describing them.
Later,
Liz

I place plastic deli cup lids underneath the Cocohuts, but I only do this for breeding purposes. If you don't plan on breeding, you really dont have to put anything underneath the Coco Hut.
