I would have to agree with Mike and suggest doing a foam and clay combo on a 40gal. I think if you did it all clay you would need three people to move it. I did three sides of a 20 and I can barely budge it. They do make different color clays you can get at craft stores that might give a better look. I used clay in all my small Exos. You can see them in my photo album. The best thing about it is you don't have to wait after you're done. You can put the frogs right in.
Cheri you're right the tanks can become very heavy. I had to have help moving my 40 vertical from the basement to the room upstairs. As for color you can put some red clay into the mix to change the color a bit. I really don't mind the color as I'm hoping the moss and creeping fig will cover most of the background. Also as you mentioned I did forget to add that I press into the clay more peat or coco fibers or wood chunks. This breaks up the look as well as provides surface area for things to grow on or from.
