I just finished my custom built tank, I had a 40 gallon breeder and it was just too small so I took the background did some photo shop to the poster and used a broken longboard skateboard deck for the basking spot and my little buddy seems much happier with his upgrade and room. I really liked the exo terra style tank with the bifold doors so I integrated that in with out spending the money on that tank.
not that it's a huge deal, but if you take that background pic and invert it horizontally, print it out and replace the pic on the right, you can create a more scenic landscape, make it look more like a sunset...
ah the magic of MSpaint.
