I have been brain storming on how I could lay this out for some Darts or Mantellas that would use the vertical space. I am thinking I want a lot of Moss and ferns in this one with some gentle sloping walls to make it easier for them to use some of the upper ares. Maybe slope the side a bit till about halfway up and then make them more vertical with branches reaching up towards the top with Brooms all over them.. Not sure... I started price checking things to determine what it might possible cost to do this type of a build and Folius is out of Hygrolon large sheets with no ETA on restocking them. This concerned me because I would hate to plan on using that product and it take 2 - 4 months for him to get them in stock. So now I am looking at other options for do some moss walls on the sides of the tank.
