I have done two things for basking "structures" in Bender's tank. First, I went to the beach and got drift wood. I took it home, soaked it in water, and baked it for a while. (if you don't live by the beach any other wood could work, even fire wood, just make sure the size is appropriate for your dragon and that you bake it because you don't want to introduce foreign "stuff" to it's environment.) the other way is stacking rocks. They don't need to be big, just enough to give a comfortable pile. They are also easier to clean and add. Just boil them to put them in the tank. I prefer the rocks because they file the dragons nails and are far easier to clean. You could also use a repti-hammock, but it's definitely not the best solution. Hope this helps
