Thanks all. I am planning to add mosses on the bottom for greenery and a few areas as leaf litter sections. Using crushed almond leaf that I had around for my bettas. I would like to find something natural to add to the back wall that will grow and spread. Right now I am thinking of adding java moss as I find that to be easy. If anyone has any suggestions please pass them along. This is also my first setup with a false bottom as my pervious setups involved having waterfalls, pools and so on. This time I am trying to go for something different and more relevant to a climber rather then a swimmer species. I was inspired to try this based of some of Bill's stuff. The exo terra is the cubed 18 x 18 x 18. Would, if I have a lot of plants and such, I be able to keep 4 mantellas in this comfortably or is that pushing it? I have two in there at present. Should I cover the top to maintain humidity or partial cover it or leave it open as I am a bit confused if they prefer cool or warm / humid. I am ordering wingless fruit fly culture to provide a food source. I have noticed that they have a preference for the croton plant over the sheffllera and ivy that are presently in there.
