Why You Should Use a Fish Tank Background | The Aquarium Guide
Aquarium backgrounds give some oomph to your setup, making your tank look bigger and fuller, without taking up valuable space. You can add a backdrop on the outside of your tank at any time, whether the tank is full or empty. But if you prefer to place the image on the inside of the tank, it'll take some work. Interior backdrops require your tank to be completely empty, meaning you'll need to find temporary housing for your fish, if applicable. Either way, a new background gives a whole new life to your underwater setup.
