The tank and stand were made by Azoo but I bought them on closeout from Aquatic Ecosystems in Central FL. Because the company is close to where I live, I was able to pick them up in person; however, shipping is reasonably priced too. http://www.aquaticeco.com/subcategories/3938/3D-Acrylic-Tanks
I added a 3D background which happened to fit perfectly, and was pretty much ready to go. I agree, I like naturalistic setups and think they not only complement the animals but contribute to their behavioral enrichment as well. My turtle has been in this setup for almost 4 months but I still find him exploring around it. Every few months I completely drain and rearrange it, and he seems so happy afterwards (and I don't get bored looking at the same thing forever, haha).
