This thin and extremely flexible back wall in distinct yet mystical sand colours has been recreated true-to-life from the underwater world. Soothing, wave-like colours in the background help form the basis to creating an aquarium close to nature. Its stylish design harmonises perfectly with other decorative elements and is particularly versatile. The Flex back wall can be inserted into any aquarium quickly and easily. Thanks to its flexibility, it can be trimmed to any dimensions in the aquarium. And for an authentic 3D effect, you can simply stick our rock ornaments onto the wall to create a lively water world feeling. Suitable for freshwater and saltwater. Made in high quality and adaptable in every way.
