Betta fish, also known as Siamese fighting fish, are popular pets due to their vibrant colors and unique personalities. Their small size makes them suited for a variety of tank setups, allowing owners to get creative with decorative elements and themes.
The number of people keeping their betta fish in a themed, aquascaped tank has drastically increased over the last couple of years. After seeing so many people reaching out with various questions about betta tank ideas, we decided to publish this dedicated article to try and help as many of our readers as possible.
Betta fish can work in a number of different tank sizes with 5 gallons often being the minimum recommendation but we actually recommend a 10 gallon tank for this type of setup.
This is due to the aquascape design taking up so much space in the aquarium that in this specific case, a 5 gallon tank is simply too small so always try to use a 10 gallon tank or larger if possible.
Natural Biotope
Creating a natural biotope for a betta fish is an excellent way to replicate their natural habitat and provide a thriving environment. A betta biotope aquarium mimics the native environment of the fish, which typically includes aquatic plant species native to Southeast Asia, leaf litter, driftwood, and stones.
By incorporating these elements into your betta tank setup, you can provide them with a living space that closely resembles their natural home.
Some popular plant choices for a betta biotope include Java Fern, Java Moss, and floating plants. These provide natural cover and mimic the densely vegetated waters in which betta fish are accustomed to living. Additionally, Indian almond leaves can be added to the tank, as they release tannins that create a blackwater environment similar to the betta’s natural habitat.
Substrate selection is also an important aspect of a betta biotope. Opt for a substrate that resembles the natural bottom in their native region, such as sand or fine gravel. This will not only lend an authentic feel to the tank but also provide excellent support for plant growth and encourage natural behavior among the fish.
Incorporating other natural elements, such as driftwood and stones, into the aquarium can help to create a more genuine biotope. These elements offer hiding spots for your betta fish and enhance the overall aesthetic of the tank. Arranging the driftwood and stones in a way that mimics the natural landscapes of Southeast Asia can further improve the authenticity of the biotope.
Temperature and water quality are additional factors to consider when setting up a betta biotope. Aim to maintain a temperature between 78°-80°F and ensure that ammonia, nitrite, and nitrate levels are within acceptable ranges. Proper water conditions will contribute to the overall success of your betta biotope and keep your fish healthy and happy.
In summary, building a natural biotope for your betta fish involves careful selection of plants, substrate, and hardscape materials, as well as maintaining appropriate water conditions. By creating a habitat that closely resembles their native environment, you can promote the well-being and longevity of your betta fish.
Bonsai Betta Tank
Incorporating artificial bonsai trees into your betta fish tank not only adds a touch of elegance and sophistication but also provides several functional benefits. Artificial bonsai trees are rapidly becoming popular choices for aquascaping, due to their aesthetic appeal and ease of maintenance.
One of the main advantages of using artificial bonsai trees in your betta tank is the additional hiding spots they offer for your fish. Betta fish, being territorial and sometimes shy, appreciate having secure areas to retreat and rest. These trees create ample cover for bettas, reducing potential stressors and promoting a healthy environment.
When it comes to designing your bonsai landscape, it’s essential to properly anchor the artificial tree onto a suitable surface like rocks or driftwood. This ensures stability and prevents the tree from toppling over and causing harm to your betta fish. Moreover, placing the tree in a visually appealing position will enhance the overall appearance of the tank and create a stunning aquascape.
Combining the bonsai landscape with other natural elements such as leaf litter, like Catappa leaves and Alder cones, can further accentuate the tank’s aesthetics and improve water quality. The tannins released by these leaves not only contribute to replicating a natural betta habitat but also promote their wellbeing.
To create a balanced and harmonious setup, you can also integrate live plants like Java moss, Anubias, or floating plants around the bonsai tree. These plants will purify the water, provide additional hiding spots, and contribute to a healthy ecosystem that your betta will thrive in.
You can purchase your artificial bonsai trees online that are pre-made but the video below goes over how you can manually make them yourself.

Incorporating plenty of hiding spots for your betta fish is crucial when designing a mountain scape. These hideouts will not only provide shelter and security for your fish but also contribute to their overall health and well-being.
It is essential to take into account the specific needs of your betta, including their size and preference for hiding spaces. You can achieve this by strategically placing caves, rocky overhangs, or even creating nooks and crevices within the mountain scape.
In conclusion, a mountain scape is a creative and visually appealing way to enhance the living environment for your betta fish. Whether you choose real or artificial stones or opt for a 3D printed design, ensure that there are ample hiding spots to cater to your betta’s needs. An eye-catching mountain scape will not only provide a visually pleasing aquascape but also contribute to your betta’s health and overall well-being.
Moss Covered
Incorporating moss into a betta fish tank can create a visually stunning environment while also providing several benefits for both the fish and the tank ecosystem. One approach to achieve this look is by covering driftwood, stones, and the tank floor with various types of mosses. Popular choices include Java moss, Christmas moss, and flame moss.
Java moss is particularly well-suited for betta tanks due to its versatility and ability to thrive in a range of water conditions. It can be attached to driftwood, rocks, or other decorations, creating a textured, natural appearance.

Blackwater Tanks
Blackwater tanks are an exceptional choice for betta fish enthusiasts who want to create a more natural and visually striking environment for their pets. These aquariums seek to mimic the dark, tannin-rich waters that bettas originate from, providing a habitat close to their native conditions.
Setting up a blackwater tank requires a slightly different approach compared to traditional aquariums. To achieve the dark water effect, tannins from botanical materials such as Indian almond leaves, peat moss, and driftwood are added to the tank. These natural elements not only create the dark water aesthetic but also lower the pH levels, making it more suited to betta fish that thrive in slightly acidic water.
Incorporating live plants is another essential aspect of designing a blackwater betta tank. Many aquatic plants thrive in these conditions, such as Java fern, Anubias, and Amazon sword plants. Live plants not only add to the biotope’s visual appeal but also contribute to water quality by absorbing ammonia and nitrates produced by the fish.
When aquascaping a blackwater tank, balance is key. The aim is to create a comfortable and stimulating environment for your betta without overcrowding the tank. To achieve this, arrange driftwood, rocks, and plants in a way that provides both open swimming areas and hiding spots for the fish to explore.
Maintenance of a blackwater tank is essential to ensure the health of your betta fish. Regular water changes remove excess tannins that may make the water too dark, affecting the fish’s visibility. Monitoring water parameters such as temperature, pH, ammonia, and nitrate levels is crucial as well.
To sum it up, blackwater tanks provide a unique and captivating environment that closely resembles betta fish’s natural habitat. With the right selection of botanical materials, live plants, and proper maintenance, a blackwater tank can become a stunning piece of living art and a comfortable home for your betta fish.
