Ive see all these DIY backgrounds but have no artistic ability. I came across these http://www.exo-terra.com/en/products/background.php which are used in terrariums. I was wondering if they could be used in an aquarium if completly sealed?
I think if you submerge it, it would absorb a lot of water and possibly deteriorate it over time. There are 3d ones that are sold for aquarium use.. for example:
