I'll try to get a few pics of the room setup tomorrow.
The dirt box is 6x3x3 and on wheels. That makes it moveable (not easily, but it does move) and it elevates it enough for the monitors to hide under. However, I need to elevate it a bit more as Labyrinth is rubbing his back raw by squeezing under there. Mushu never did use that as a hiding spot and does not hide all that often even when presented with hiding options. There is a 6 foot x 10"? trough for water. A big tree stump more for looks than utility. Then in the closet area I have a shelf up top for the iguana. There is also a basking lamp up there. The iguana tends to stay up there most of the time looking down on everything. A large tree branch goes up to the shelf. I have seen Lanyrinth up there a few times but not often. Petrie and Labyrinth have always both been up there and seemingly indifferent to each other's presence. There are planters on the walls which held pothos until the iguana entered the room. There is a large custom made enclosure (36"x18"x18"
mounted on one of the walls for a day gecko. Also, there is an aquarium with a tokay in it mounted on the wall as well. I had hoped these enclosures would be cool in there, but I have found I tend to neglect both geckos so I need to move their enclosures elsewhere. Occasionally, I get the itching to let the tokay run free in the room (and providing him hiding options near and on the ceiling for daylight safety). He'd be active at night while the water monitors slept. I also know that at some point he'd be eaten, which is why I never actually let him loose (I like him).
The floor is cheap vinyl tile. Not so good, I should have bought a better tile. Only dirt on the floor is the dirt the monitors toss on the floor.
If and when I remove the custom gecko enclosure, I will mount a tree limb between two walls and give the iguana another climbing area. It is also possible that with enough climbing areas I would move a second iguana into that room (probably not).
I loved the grass idea but could never get it to take root. It died off. I also potted a shrub which you can see in the pics, but the iguana ate it every time it grew sprouts and it is now dead. I still like the grass in the enclosure because it seems to keep the humidity in the dirt even though it is dead. I have gotten grass seed to take root in my timor enclosure and it looks nice. The sod pieces died.
Hope that helps.
