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.
