Hi. I recently bought frog moss for my whites tree frog tank and it got moldy. I had a layer of hydroballs, then coco fiber, then the moss. The problem is that my frogs hate the coco fiber because it clings to their skin. I can't find any live mosses and can't seem to get an dried mosses to grow and not get moldy. I saw a product in the store the other day called T-red Crab Island Climbing Background (at Petco). It claims to be made completely out of coco fibers that are compressed. It looks like a mat and is supposed to be for hermit crabs. So my question is, can I use this for my two whites tree frogs? Also, is it okay to have a layer of hydroballs underneath it for drainage?
