Instructions

    • 1

      Measure the back of your aquarium. Be sure to measure both the length and the height of the tank.

    • 2

      Cut the Styrofoam sheet so that it is the same length and height as your aquarium. Dip a sponge in some water colors and give the background the color you want. Natural colors like greens, blues and browns work well as aquarium backgrounds.

    • 3

      Use the X-Acto knife to cut ridges and gulleys into the Styrofoam. This will give the background more of a three-dimensional appearance.

    • 4

      Paint the background using your water colors. You may want to paint a realistic background to simulate a natural aquatic environment. You can also choose a more abstract background with bold colors and unique designs.

    • 5

      Glue a few plastic plants to the 3D background. This will provide a more natural appearance and bring out the 3D nature of the piece.

    • 6

      Attach the 3D background to the back of the aquarium using clear packing tape. Make sure you put a piece of tape on the top and bottom of each side of the background. This will help to secure the background in place.
