This happens to be my baby boa's tank (I'm still in the process of completing all the decor for the balls' tank).
I pretty much made all the plants myself. I just went to Wal-Mart and Michael's Craft Store and bought fake plants and cut them and glued them the way I wanted them, and I used one of those Iguana vines and glued leaves on it and wrapped it around her water dish. I also re-painted her rock hide since it was the wrong color for her "environment". And I picked up some more fake plants and a nice orange fake flower for the rest of the background, I love how its all three dimensional and not just some glued on piece of paper with a picture on it. She loves it =).
