anyone with a 3d background?

i just need some tips on how to do it. i have a 15 gallon tank and i dont want anything too big cause i dont want to lose too much tank space. i have styrofoam that is about half an inch think and i plan to make it look as though there is a wall of rocks in the background. any advice that could be given would be great!

you may want to wait until you get a bigger tank. with a tank where space is tight (like a 15 gallon) you'll have to utilize all of the space you can. a ½in. piece of styrofoam may not seem like alot, but it will have a noticable impact on the volume of water. it would be like adding another ½in. of gravel to the tank.
