  1. 1

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

  2. 2

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

  3. 3

    Use the craft knife to cut ridges and gulleys into the polystyrene foam. This will give the background more of a three-dimensional appearance.

  4. 4

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

  5. 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. 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.
