Didooou 3D Aquarium Background Sticker

Setting up or restyling an aquarium often needs a simple way to add depth and finish without rearranging hardscape. This self-adhesive aquarium background offers a high-definition, 3D-effect print designed to stick to the outside rear glass of the tank, giving a vivid backdrop while leaving the interior undisturbed.

Made from waterproof PVC, the background is durable and easy to wipe clean. The material has a protective transparent film when supplied; tear this off and press the sticker on dry, clean glass. Slight wrinkles or a floating film are noted as normal during handling, so lay the sheet flat before application and smooth from the centre outwards to reduce bubbles. This type of external, stick-on background is useful for owners who want to change the look quickly, conceal equipment or enhance perceived depth in planted or rock-based setups without contact with water or livestock.
