Once the soil and plants are selected and the aquarium technology is in place, you can dedicate yourself to more detailed work. The decoration of the aquarium back wall has only a small influence on the biotope, but is an important element to make your miniature landscape visually appealing. By attaching a background to the back wall of the aquarium, you can hide details behind a free-standing tank like wiring for the aquarium equipment.

The way in which motifs are mounted for the aquarium back wall depends on the material:

• Aquatic backgrounds in the form of simple posters or plain coloured paper are simply glued onto the back wall of the aquarium. The disadvantage of cardboard and paper: sometimes it gets wet on the outside the tank, when cleaning or changing the water. The material can become moist or warp.
• Backing films for a back wall motif are waterproof adhesive films that can be mounted onto the back wall of the aquarium.
• 3D-backgrounds are particularly beautiful: These wall panels made of aquarium-suitable material have a surface structure that imitates a natural mineral surface, for example. The 3D back walls are glued into the empty tank with silicone adhesive. Depending on the model, they give the aquarium an unmistakable look. With a bit of skill, structural back walls can also be planted with decorative moss.

All variants of aquarium back walls are available for standard tank formats – such as  Juwel or Trixie.

If you use a simple poster or cardboard as a back wall motif for the aquarium, stick the motif directly onto the outside of the glass. Secure the paper on normal areas, for example with a glue stick, and then use wide adhesive film on the edges. You can also purchase special surface adhesives in our online shop. The advantage of this simple method: the motif can be replaced every so often. Ideally, you can attach a back wall film for your aquarium before the tank is filled. This allows you to simply place the glass tank on the floor sideways and stick it on horizontally from above. This has advantages: with large-area adhesive films you have to work very precisely, since air bubbles quickly form between the film and the substrate which must then be smoothed out. This works better on a horizontal surface.

If neutral in colour or designed as a back wall motif, the aquarium back wall is ignored by the fish. However, it is different with 3D backgrounds or moss walls: depending on the structure, these are interesting to the fish and other residents as a hiding place. It’s important to make sure that small fish cannot accidentally get trapped behind the back wall.
