Ok, here's what I did. I left the coconut fiber in there, so I could keep my slope. Hubby bought me a moss terrarium pad, which I put on top of it (it fit perfectly.) On top of that, I have all my plants, decor, etc., so very little of it actually comes into contact with my guys. I actually feed them on the dock in the water (I noticed the other day and last night that when I opened the lid, all three came to the dock and waited patiently.) No crickets ventured to the moss side last night (due to the divider there) and those that barely touched the water were scooped up almost immediately. So gonna continue this way unless something changes. I do have a filter in my water area, so I'm good there. But I took out all the water and cleaned everything before putting the moss pad in there (looks brand new again.) They have actually ventured a little more this morning into the dry area since I put that down, they actually used their basking rock. So hopefully they're a bit happier now (I know I would be if I was no longer coated in all that fiber!)

I do know I'll still have to keep an eye out for mold under the moss mat/on the fiber and all that. I read that somewhere else last night why researching using a mat with them.
