I'd second Scott's comments. The Juwel background is pricey for what
it is, but it is neutral and blends realistically into any tank set
up you wish to make. I would imagine that the more elaborate 3D
backgrounds (which are more expensive still) which simulate submerged
roots or rock faces or whatever are kind of restrictive.
The half-inch of real depth that you lose with Juwel is more than
compensated for by the illusion of greater depth that it creates.
