Another material that is used commonly for this is polystyrene. You can cut the polystyrene into shapes and either build up a background or just stick the shapes onto the glass. They can be painted to look like rocks etc, and will last for years. There is also another variant to this method, by using the polystyrene as a mould and covering it with fibreglass or cement, letting it dry and then removing the polystyrene, leaving you with a solid ornamental background that can be attached to the back of the tank. It may take a few days to create, but when done well, it is one of the most effective backgrounds I have come across. Just be sure that it is well secured and that fish can’t get trapped behind the moulding.
lifelike, colorful, 3D and other aquarium & fish tank backgrounds
Whether your fish habitat is a tiny 5-gallon tank or a giant saltwater reef aquarium, a backgrounds can turn a mediocre-looking fish tank into a decorative and aesthetic piece. Aquarium backgrounds, which fit inside or out of the tank, may serve to comfort the fish with a static viewscape. Backgrounds attached to the back of the tank eliminate algae-inducing natural light from that side of the aquarium and help to keep the tank clean.
