There are plenty of ways to decorate and personalise your fish tank. But one of the easiest, most striking ways to transform your aquarium is to buy a fish tank background. These backgrounds offer a unique way to bring depth, colour, and theme to any aquarium.

What are fish tank backgrounds?
While some fish tank backgrounds are like giant posters for your fish, others are 3D textured backdrops that you can fit or glue inside your aquarium.
Our fish tank backgrounds include scenes of ocean water, cliff drops, and rockeries. So, whether you’re after a stick-on ocean backdrop or a 3D rock formation, we have a fish tank background that can help you create your under-the-sea vision.
Not only do these backdrops provide a scene that brings your fish tank to life, but they’re also great for hiding your heater tubes and filter.
Our four favourite fish tank backgrounds
These are just a few of our favourite fish tank backgrounds.

1. Juwel fish tank backgrounds
This stone granite fish tank background from Juwel can help you create a striking rock structure for your aquarium. The natural grey tones and the background’s illusion of depth give this backdrop an authentic feel.
This background measures 60 x 55 cm, and you can cut the background to fit your fish tank, making it easy to install inside your tank. The background also has a modular design, which makes it expandable.
We stock variations of this Juwel fish tank background, including the Cliff Dark, Cliff Light, and Stone Clay designs.
2. Juwel rear wall posters
This double-sided fish tank poster from Juwel gives you two backdrops for your aquarium, which you might like to switch between each time you do a water change.
Choose between a natural rocky scene and a bright underwater landscape with mixed vegetation.
This fish tank poster measures 150 x 60 cm. Like the Juwel fish tank backgrounds above, you can cut this poster to size. However, these posters attach to the back wall of your fish tank rather than slotting inside the tank.
We also stock variations of this Juwel rear wall poster, including a:


3. Juwel filter covers
If you’re interested in covering your Juwel internal filter without inserting a background that will fill your fish tank, a Juwel filter cover is perfect for you.
We love this two-piece Juwel filter cover, which features a ‘Cliff Dark’ design that replicates the appearance and texture of a cliff.
We also stock variations of this Juwel filter cover, including the Cliff Light and Stone Clay designs.
This filter cover measures 55 x 18 cm.
4. Back to Nature rocks
Fishkeepers who are looking to design a natural fish tank will love Back to Nature’s rock aquarium backgrounds.
These slim backgrounds are approximately 10 mm thick and come in two colours: Red Rock and White Limestone.
These backgrounds are available in heights of 45 cm for 50 cm fish tanks and 55 cm for 60 cm fish tanks. Each height comprises four sections that you can interlock to cover the back of virtually any fish tank.
