Who Should Buy an Aquarium Background

If you have an aquarium, you should definitely consider adding a background! These colorful printed sheets are designed to sit either inside or behind your aquarium. They help to add interest, depth of field, and help to show your fish off as best as possible.

Aquarium backgrounds are available in a huge range of colors – from classic coral reefs to restful seabeds, and even scenes like galaxies and forests. Some aquarium backgrounds are three-dimensional and are designed to sit within your fish tank.

Whatever type you choose, these backgrounds certainly do a great job of making your aquarium look attractive and eye-catching.

Important Features to Consider

  • Type of attachment. Aquarium backgrounds usually attach to your fish tank in one of three ways – taped, static cling, or fully adhesive. Taped backgrounds can simply be attached using a small piece of tape (usually supplied with the background) at each corner. Static cling backgrounds can be applied by cleaning your fish tank then spraying the area to be covered with a small amount of water. You can then lay the background on, and remove any bubbles using a squeegee. Fully adhesive backgrounds are covered with a thin layer of glue that sticks to the back of your tank. They’re harder to apply than the previous two methods.
  • Size. It’s important to choose a background that suits the size of your tank. Some can be cut to size, and will often include grid-lines on the back to help you achieve this neatly. Others have a scene that is designed to fit the whole tank, and cutting them will remove some of this scene.
  • Placement. You can choose to place your background on the rear side of your tank only. This is the most popular option. Some aquarium owners decide to buy a background which is wider than required and then wrap it around three sides of the tank to create an even more realistic effect. The choice is yours!
  • 3D or printed. Most aquarium backgrounds are two-dimensional and printed on photographic paper. It is also possible to buy three-dimensional backgrounds, which are usually designed to mimic rocks. These are placed within your tank, rather than on the outside.

Frequently Asked Questions

What is an aquarium background?

An aquarium background is designed to sit behind your tank. It provides depth, color, and interest. They come in many different designs, so you can choose from things like a tropical coral theme, restful mangroves, sandy seabeds, and many more!

How do you attach an aquarium background?

This depends on the manufacturer, so always make sure to read the instructions! Some aquarium background can be attached with tape, while others use static cling to fix firmly to the back of your aquarium. We outlined the most popular methods in more detail above.

Do aquarium backgrounds go inside or outside?

The majority of two-dimensional aquarium backgrounds sit outside your tank, on the back wall. If you choose a three-dimensional background, these are designed to go inside your tank. Check the details from the manufacturer to make sure!

Do I need an aquarium background?

It’s not an essential part of your aquarium, so if you’re starting with the bare minimum then don’t worry about buying a background right away. But backgrounds are great for covering up the cables that will be running behind your tank, as well as adding a background which can make it easier to see your fish.
