Best Fish Tank Decoration Ideas

By John DoeLast update: 2023-08-30

Decorating an aquarium can be incredibly fun. If you're the first to set up an aquarium, it's a good idea to take some time to plan out the attractive theme before incorporating layers of substrate, water, and fish. This is a good time to buy and think about decorative touches. We are pleased to present you with the best fish tank decoration ideas.

1. Decide on a topic

If you want your aquarium to stand out, one of the best ways to approach tank decoration is to decide on a theme. Many people tend to keep it simple and choose decorations inspired by the water, like sunken ship decorations and divers figurines. Or these decorations may be very eye-catching, but they are quite old. Consider the ages of history and think about incorporating miniature statues and carvings.

Or cityscapes submerged in water, with towers toppling and skylines half-submerged in the substrate. Regardless of the theme you choose, make sure any decorations you buy are suitable for use in the aquarium.

2. Make use of plants

You can use plants to create aquarium-friendly plants. You can choose aquatic plants that can be stacked in a bed and stay underwater, or choose floating plants that will drift throughout the interior of the tank. When choosing plants for aquariums, make sure to choose varieties that won't grow larger than the size of your aquarium.

Low-maintenance species should be selected whenever possible and ensured that the tree will not produce harmful pollutants. Another thing to remember about plants is that you should need sunlight to grow. Some plants need their full nourishment from natural sunlight coming through a window, although other varieties will require the installation of a dedicated UV light.

3. Keep it simple

Using colored gravel and substrate is always a good way to introduce some personality to the aquarium. Pebbles come in a variety of sizes, shapes, and shades, providing a complete choice when deciding on a vibrant color palette. Most pet stores and aquatic retailers will offer a variety of tank decorations. These are often quite expensive compared to everyday decorations, but the main benefit is that they are suitable for use in aquarium water and will not harm the fish.

If you choose a more natural option, purchase specially treated driftwood and organic objects that can be used to recreate the look of the riverbed. Or use supporting images. They are only really suitable for tanks placed with one side against the wall. Just picture, print to size, and attach it to the outside of the tank for a nice backdrop. Just make sure the image is printed on a water-resistant material to ensure occasional splashes of water won't cause any of the ink to smudge and smudge.

4. Decorate the aquarium as a statement

You can integrate aquarium design ideas with the walls to fit the room in a cozy way. Make sure to choose the right species of fish and other creatures in the aquarium and always pay attention to providing clean water. At the same time, combine the surrounding walls with the aquarium for a coherent look

5. Aquarium decorating ideas for the center table

Give a unique look to that boring old coffee table with a fish tank cabinet right under the table. Here it not only gives the living room an absolute masterpiece but also brings serenity and warmth to the room. Combine it with a pair of LED lights and other decorations for the central coffee table.

6. Aquarium design ideas for the wall corner

It is possible to decorate an aquarium that is not as large as the entire wall, a corner fish tank may suit you. It brightens up the corners of the often overlooked edges of the wall and the aquarium isn't too big to manage.

7. Aquarium decoration side table

Turn your bedside table into an aquarium. The aquarium near the bed allows you to admire your pet fish at any time, which creates an interesting feeling. It is also a relatively low maintenance cost. This is also one of the great ideas for kids and teens who want a fun aquarium decoration while still being safe enough for them.

8. Decorate the aquarium as a partition

Wall partitions come in many shapes and forms. Instead of a boring old dividing wall, use a large vertical aquarium as a blurred boundary between the two rooms. This can easily turn an ordinary wall into something unique.

9. Bedhead aquarium design ideas for bedroom

Let the aquarium transform the mundane bed into something amazingly unique that anyone who looks at it will be in awe of. Decorate by personal choice, you can choose a lavish and large aquarium decoration, or you can choose a smaller, minimalist decoration.

10. Rocks and gravel

Rocks and pebbles are popular choices for the best aquarium decoration. They come in a variety of colors and sizes and can be used to create a natural habitat for fish.

Usually, gravel is also relatively cheap and easy to obtain, making it a great choice for aquarium owners on a tight budget.

Rocks and gravel can be used to create caves and hiding places for your fish, can help reduce stress levels, and used to anchor live plants.

However, rocks and gravel can pose a risk to fish if they are not cleaned properly before being added to the tank. Small pieces of gravel can break off and get stuck in the gills, while large rocks can damage the fins or even crush the fish if they fall. But it is important to thoroughly wash all rocks and gravel before adding them to the aquarium.

Always avoid using rocks that are too sharp or jagged as they can injure the fish.

11. Tanks with vision

Aquariums with building views are becoming more and more popular and can be considered by the beauty it brings to be one of the best aquarium decorations that you can use on the aquarium. They provide a beautiful way to display fish while adding a unique touch to the room.

It is advisable to purchase a ready-made aquarium with a control panel. These aquariums are usually made of acrylic and have a large panel on one side. On the other hand, you can build your aquarium with a view. Combining a standard aquarium with a glass panel or picture frame can make it done easily. This option allows for more flexibility in size and shape, but it will require some basic carpentry skills.

12. Unique decorations and statues

While traditional decorations like rocks and plants can certainly add interest to your tank, sculptures, and statues help create a one-of-a-kind look.

Hideout: Decorations and statues can provide much-needed hiding places for fish, which can help reduce stress levels.

Breeding Place: Some decorations and statues have nooks and crannies that can serve as spawning grounds for fish.

Focal Point: Sculptures and statues can make a great focal point in an aquarium. Be sure to avoid any decorations with sharp edges or small parts that could split and be swallowed by the fish.

13. Fun and functional accessories

Decorating an aquarium is a fun and rewarding experience. Not only can you create a visually appealing environment for your fish, but you can also provide them with useful hiding places and other accessories.

Some accessories are more functional than the beauty they add to an already existing aquarium.

Functions include aeration, for one. Other accessories may be solely intended to provide the fish with shelter or sleep. However, others may contain chemicals that help keep the water in the tank clean and clear.

Make sure they are safe for both the fish and the aquarium. Choose items that are safe for fish and won't break down in the water. Choose decorations that have the right size for your tank.


When it comes to the best fish tank decoration ideas. The best way to find what works is to experiment and have fun. There are no rules when it comes to aquarium decoration, so let the creativity shine. With a little planning, you can create an aquarium that is both beautiful and functional.
