Can you put a background in a fish tank? Yes, absolutely! Adding a background to your fish tank is a fantastic way to enhance its visual appeal, create a more naturalistic environment for your aquatic inhabitants, and even help your fish feel more secure. This guide will walk you through the process, offering easy steps and exploring the best methods for bringing your aquarium to life.
Why Add a Fish Tank Background?
Adding a background isn’t just about aesthetics; it serves several important purposes for both your fish and your enjoyment of the aquarium.
Benefits of a Fish Tank Background
- Improved Aesthetics: A well-chosen background can transform a plain glass box into a stunning underwater landscape. It hides unsightly equipment like filters and heaters, and can make the tank appear larger.
- Fish Security: Many fish species are sensitive to light and sudden movements outside the tank. A background provides a visual barrier, reducing stress and making them feel safer. This can lead to calmer, healthier fish.
- Creating Depth: A good background can create the illusion of depth, making your tank look much more expansive and immersive. This is key for realistic aquarium backgrounds.
- Highlighting Colors: The right backdrop can make the vibrant colors of your fish and live plants pop, creating a more dynamic and engaging display.
- Concealing Equipment: No one likes seeing wires or filter tubes. A background effectively hides these distractions.
Types of Aquarium Backgrounds
There are many different types of aquarium backgrounds available, each offering unique looks and installation methods. Choosing the right one depends on your desired aesthetic, budget, and ease of installation.

How to Attach an Aquarium Background: Best Methods
The method for how to attach an aquarium background depends largely on the type of background you choose and whether you are installing it on the inside or outside of the tank.
Attaching Backgrounds to the Outside of the Tank
This is the easiest and most common method, suitable for most printed and paper backgrounds.
Method 1: Using Tape (for Printed/Paper Backgrounds)
This is the simplest way to attach a printed or paper background to the back of your tank.
What You’ll Need:
- Your chosen background (printed plastic or paper)
- Clear packing tape or black electrical tape (for a cleaner look)
- Scissors
- A clean, flat surface
- A ruler or measuring tape
- A squeegee or credit card (optional, for smoothing)
Step-by-Step Installation:
- Prepare the Tank: Ensure the outside of your fish tank is clean and dry. This will help the tape adhere properly.
- Measure and Cut: Roll out your background material. Measure the height and width of the back of your tank. Cut the background to size, adding a little extra on the sides and bottom if you plan to trim later.
- Position the Background: Carefully place the background against the back of the tank. Ensure it is centered and straight. You can use a few small pieces of tape to hold it in place temporarily.
- Apply Tape: Starting from the top, apply strips of clear packing tape or black electrical tape along the edges of the background, securing it to the glass. For a seamless look, overlap the tape slightly.
- Smooth Out Wrinkles: If you notice any wrinkles, gently lift the taped edge and reapply, using a squeegee or credit card to smooth out the surface as you go.
- Trim Excess: Once securely taped, use scissors or a craft knife to carefully trim any excess background material from the sides and bottom for a neat finish.
Tips for Success:
- Work in a well-lit area.
- Have a friend help to hold the background steady.
- Use black tape if you want to block out all light and achieve a sleek look, especially if your tank is against a wall.
- For paper backgrounds, be extra careful as they can tear easily.
Method 2: Using Spray Adhesive or Silicone (for More Permanent Installation)
This method is more permanent and can give a cleaner look, especially with thicker plastic backgrounds.
What You’ll Need:
- Your chosen background (thicker plastic or vinyl)
- Aquarium-safe spray adhesive or 100% silicone sealant (clear)
- Newspaper or drop cloth to protect surfaces
- Gloves
- Spray bottle with water (if using silicone)
- A squeegee or plastic scraper
Step-by-Step Installation:
- Prepare the Tank: Clean and dry the outside of the tank thoroughly.
- Protect Surfaces: Lay down newspaper or a drop cloth to catch any drips.
- Apply Adhesive/Silicone:
- Spray Adhesive: Lightly spray the back of the tank or the back of the background material. Follow the manufacturer’s instructions for drying time.
- Silicone: Apply a thin, even bead of aquarium-safe silicone around the perimeter of the back of the tank.
- Position and Press: Carefully position the background material onto the silicone or adhesive. Gently press it into place, working from the center outwards to push out any air bubbles.
- Smooth and Secure: Use a squeegee or credit card to smooth out the background, ensuring good contact. If using silicone, you can lightly mist your finger with water to help smooth the edges.
- Cure Time: Allow the adhesive or silicone to cure completely according to the manufacturer’s instructions before adding water to the tank. This can take 24-48 hours.
Considerations:
- Aquarium Safety: Always use products specifically labeled as aquarium-safe.
- Permanence: This method is more permanent. If you want to change the background later, it can be more difficult to remove.
Attaching Backgrounds to the Inside of the Tank
This method is typically used for more elaborate DIY aquarium backgrounds or custom-molded 3D backgrounds. It allows for a truly integrated look and is essential for creating realistic aquarium backgrounds with rockwork and plants.
Method 3: Silicone and Substrate (for 3D or Naturalistic Backgrounds)
This is the most involved but also the most rewarding method for creating immersive environments and for attaching heavier or custom-made backgrounds.
What You’ll Need:
- Your custom or 3D background panels
- Aquarium-safe silicone sealant (clear or black)
- Gloves
- Paper towels or rags
- Aquarium-safe substrate (sand, gravel, small rocks)
- Spray bottle with water (optional, for smoothing silicone)
- Tools for shaping silicone (e.g., plastic spoons, craft sticks)
Step-by-Step Installation:
- Prepare the Background: Ensure your background panels are clean and dry. If they are modular, plan how they will fit together.
- Apply Silicone: Apply a generous amount of aquarium-safe silicone to the back of the background panels where they will touch the tank glass. You can also apply silicone to the tank glass itself for extra adhesion.
- Position and Press: Carefully place the background panel into the tank. Press it firmly against the glass, ensuring good contact. You may need to support it while the silicone cures.
- Add Substrate (Optional): While the silicone is still wet, you can press aquarium-safe substrate into the silicone to disguise the seams and create a more natural texture. This is a great technique for decorating fish tank backgrounds.
- Smooth and Shape: Use damp paper towels, gloves, or tools to smooth and shape the silicone. You can blend it into the background panels or substrate for a seamless look.
- Cure Time: Allow the silicone to cure completely. This is critical for aquarium safety. It typically takes 24-48 hours, but check the product instructions. Ensure good ventilation during curing.
- Rinse and Fill: Once cured, you can rinse the tank gently to remove any loose particles, then fill it with water.
Tips for Custom Backgrounds:
- Pre-cure in a test tank: For complex setups, consider pre-curing the background outside the main tank to ensure it holds together and doesn’t leak any unwanted substances.
- Create a natural flow: Think about how the background will integrate with your aquascape. Use the background to create caves, ledges, and hiding places.
- Consider creating depth: Layering different background panels or adding substrate in varying thicknesses can significantly enhance the sense of creating depth in fish tank aquascapes.
Easy Aquarium Background Ideas
Exploring different aquarium background ideas can spark creativity and help you achieve the perfect look for your tank.
