I recently had a local customer here who wanted a unigue background for his tank and came up with an idea for something that might interest some of you. I know he has bee thrilled so far and Im waiting anxiously for some photos. Ill post a link for what he used but if you click on the stained glass link youll see a few odd options. With the one he chose he had to seal it to thie inside of aquarium and match the seams as the sizes were too small for him. Im sure they deal with the public and ship as well but its worth a call.
