Fitting a fish tank background is an easy, inexpensive way to add individuality, perspective, and depth to your aquarium. 

Aquarium backgrounds can be used to brighten up a tank that doesn’t have much decoration, and using rock aquarium background cling vinyl is an excellent way of creating the perfect ocean backdrop for a saltwater setup without cluttering valuable swimming space. 

You can buy large aquarium backgrounds, although you might prefer to use printable aquarium backgrounds or even create your own DIY aquarium background paper from scratch.
