Got some sphagnum into my container. Looks much nicer now.
Indeed mold will form around too much moisture. With the ghost enclosure above I have the one set up like a frog tank kinda. It's working on the frogs so thought I would see how the ghost does like that as well. He molted again last night pretty big! I'll have to get a new pic. They can't actually get to the water, since to them it is technically under ground under the fish rocks, frogs substrate and live sheet moss. I have also adjusted my orchid spraying techniques so not so much water accumulates.
Here is the final thing I made yesterday waiting for a mantis to "move in".
