If you are asking about the first pic it is actually deceptive in the pic. The pieces of wood are just driftwood. It is the same wood that are in the other lower pics and I have positioned them in different ways over the years.
My hides in the first pic are a large tortoise shell and a black plastic ReptileBasics box hide. I have moss surrounding the black hide to camouflage it with the water bowl on top of it. If you look close you can see my BP peeking out.
If you meant the second pic thats my Hoggys tank. That is also just a chuck of driftwood. I set it up to give the look of a tree and if I was to flip it around it really looks like a tree. How I have it right now it creates a subterranean cave which is perfect for my hoggy that loves to burrow. She burrows tunnels all through the substrate that come into the cave area I created.
All the driftwood I have came from the pet store. its nothing special, just pieces I found and liked the shape as it fit my intended use well.
All the green leaves on the tank walls are just the suction cup kind mixed up and hung in a way to give the tank more of a natural look.
