Betta fish are one of the most popular fish in the aquarium hobby, and they have also become a favorite among aquascapers.

This blog post showcases 18 captivating betta fish tank ideas to inspire your own aquarium setup.

From beginner-friendly designs to more advanced aquascapes, these ideas showcase the creativity and beauty that can be achieved in a betta tank.

Betta Fish Tank Ideas By Horizon Aquatics

Horizon Aquatics are a British aquascaping specialist in North-East England with co-owners Nicole and James also having a beautiful gallery featuring a wide range of aquascapes.

I feature many aquascapes from their gallery in my aquascaping ideas article but I have chosen three of my favorite tanks that a betta fish can thrive in for this article.

The first tank features a beginner-friendly island composition, using rocks and driftwood as the foundation for various aquatic plants.

Java fern is utilized as a tall background plant, adding height and broad leaves to the design.

Most plants in this setup are anchored to rocks and driftwood, making it ideal for popular, low-maintenance epiphytes such as:

These easy-to-care-for plants come in a variety of colors and leaf shapes, allowing beginners to create a beautiful aquascape that is perfect for betta fish.

This next betta fish tank idea demonstrates that low-tech tanks can achieve stunning results with red plants.

The team at Horizon Aquatics initially stocked the tank with minnows, but a betta fish would thrive just as well in this setup.

Consider using Ludwigia Mini Super Red as your primary plant, and heavily plant it in the tank. Pair this with a blue or green betta fish to create a striking contrast against the red plants.

Additionally, a Red Tiger Lotus can be placed towards the rear of the tank to add diverse leaf shapes while maintaining the red theme.

Driftwood and river pebbles complement this tank style perfectly, allowing you to use affordable hardscape options to achieve impressive results without breaking the bank.

This next tank was created by Charlotte (@PlentyOfBettas), who showcases a variety of stunning betta tanks on her social media, all designed for her pet bettas.

Displayed in the Horizon Aquatics gallery, this setup is one of my personal favorites. While it typically requires CO2 injection for optimal results, it truly stands out.

Charlotte used the following plants in this scape:

The vibrant reds and greens of the plants contrast beautifully with the brown driftwood, creating a dynamic environment where a betta fish can truly shine.

Ludwigia Mini Super Red is an excellent choice for maintaining the red hues even without CO2 injection.

While maintaining a thriving carpet without CO2 is challenging, plants like Eleocharis Acicularis can work, though they require regular trimming to keep a flat, carpet-like appearance.

Fortunately, Charlotte and the Horizon Aquatics team documented the build phase of this tank, allowing everyone to follow along and replicate the design.

An Island Compesition Aquascape

This island-style aquascape is an excellent choice for bettas, though it is more suited to intermediate to advanced aquascapers. For best results, CO2 injection is recommended as several plants in the scape require it to thrive.

The Horizon Aquatics team used these plants in the aquascape:

While this specific setup might seem complex, you can still create simpler, budget-friendly island aquascapes suitable for a betta fish.

The wide range of colors, textures, and leaf shapes in this aquascape ensures that any betta will stand out beautifully.

Regular maintenance is essential for this type of aquascape, as the stem plants will continually grow towards the light source, requiring frequent trimming to maintain their dome-like shape.

Just like many of the other aquascapes in the Horizon Aquatics gallery, Nicole and James have a video going over this particular aquascape that you may find helpful.

Ideas For Your Betta Tank By Re-Scapes

Our next featured aquascaper is Rachel from the Re-Scapes Instagram account who has shared her work on YouTube and social media.

She has several beautiful tanks that can work well with betta fish on her social media but I have chosen my favorite three to feature in this article.

First up is this cube tank, perfect for a betta fish. It features plenty of live plants that provide hiding spots and enhance the overall design.

This setup is both beginner-friendly and budget-friendly, making it ideal for those new to aquascaping.

Start with cheap sand or gravel as the substrate, and add black lava rocks for their low price and solid color. For vertical driftwood pieces, use something like Talawa wood.

Once the hardscape is in place, you can add standard epiphyte plants such as:

In this particular aquascape, Rachel has used several java ferns as background and midground plants, with a small number of stem plants on the right-hand side.

Smaller anubias and bucephalandra variants can be used for detailing on the rocks in the foreground, completing the tank’s look.

The abundance of bright green in the tank will make a bright red betta fish stand out, making it easy to see.

The simplicity and low cost of this design make it one of my favorite betta fish tank ideas, and I have recommended it as inspiration for several beginners.

This next betta tank idea follows a similar style to the previous one, with the aquascape centered around bogwood, seiryu stone, and live plants.

Fortunately, bogwood and seiryu stone are cheap and easy to find in aquascaping stores. However, finding a piece of bogwood as detailed as the one Rachel uses can be challenging.

After securing the hardscape in the tank, you can add epiphyte plants to complete the aquascape.

Rachel uses bucephalandra and various types of java fern effectively in this setup. Both of these plants are beginner-friendly and thrive in low-tech tanks.

This betta tank demonstrates what can be achieved with a low-tech setup if you invest time and effort during the planning stage and find the perfect piece of driftwood for your project.

Thankfully, Rachel recorded large sections of the tank build and has a video on her YouTube channel going over the tank setup.

This next betta tank idea emphasizes hardscape, a style that has been growing in popularity each year.

It’s like a wood-based Iwagumi aquascape, where the main focal points are long, vertical pieces of driftwood rather than rocks or plants.

Small pieces of bogwood are typically very affordable, making this a budget-friendly option. However, you can opt for more expensive types of wood if you prefer.

Regarding plants, almost any kind will work, but it’s best to avoid long stem plants in the rear of the tank as they can detract from the focus on the wood.

Betta Tank Inspiration By Cedric_Scape

Next up, we have a French aquascaper who goes by the handle Cedric_Scapes and shares photographs of his aquascapes on his Instagram page.

Cedric has a wide range of different aquascapes on his page that are suitable for several popular types of fish but I have specifically selected some that will work well with Betta fish for this article.

This aquascape mimics the natural look of a mangrove forest with roots on each side of the tank, botanicals on the substrate, and floating plants on the surface.

Unlike most other betta tank ideas in this article, this tank features a natural, dark water look due to tannins released from the botanicals.

While some people may not prefer the dark water look, tannins are harmless to fish and can help keep bettas calm and potentially ward off infections.

The design uses a small number of plants, as dark water setups can have issues with light penetration, but this is a surprisingly easy and budget-friendly aquascape to replicate.

Your betta will have plenty of cover, as the roots and botanicals provide ample hiding spots, keeping the fish calm and happy in its new tank.

This next setup is a personal favorite of mine, as I love the use of thick stem plants in aquascapes, and I think Cedric did a fantastic job with this tank.

Although this tank features a CO2 injection inlet, you can achieve similar results by choosing plants with lower CO2 requirements and forgoing CO2 in your own tank.

A high-output light is essential for such a lush tank, and depending on the specific setup, the lighting may end up being more expensive than the tank itself.

Plant options will vary based on your use of CO2, but these gold-standard stem plants work well both with and without CO2 injection:

While several other plants could also work well for creating a lush background in this type of betta tank, I believe these four are the best choices.

This forest pathway aquascape can work well as a betta tank setup, but it’s more suited for intermediate hobbyists.

It looks stunning, utilizing a driftwood style where vertical pieces of driftwood become the main focus rather than plants or rocks.

Using bright green plants will create a strong contrast with the driftwood and ensure a bright red betta fish stands out in the tank.

This type of tank requires regular, consistent maintenance to keep the pathway through the middle clear and to manage the emergent plants.

If you’re a beginner, I recommend trying one of the other ideas featured in this article for your betta tank. However, if you have some experience with tank builds, you may be able to successfully replicate this style.

Betta Tank Ideas By Peter_Lee_Aqua

Next up, we have a Korean aquascaper who uses the handle Peter_Lee_Aqua and shares photographs of his aquariums on his Instagram page.

I love this betta tank because Peter has skillfully concealed the heater and filter behind the plants and hardscape, keeping them out of sight and maintaining the tank’s visual appeal.

This is an underrated skill that beginners often overlook.

The hardscape serves both as a striking feature and an anchor point for various epiphytes.

You can easily customize this type of aquascape with additional plants if desired, but the standard layout is already perfect for a betta fish.

This next tank is an excellent beginner-friendly and budget-friendly setup that keeps things simple while aiming for maximum output.

The tank uses aquasoil as its substrate, with a single medium-sized rock serving as a focal point toward the right.

A medium-sized piece of driftwood adds detail in the rear to midground, and using affordable bogwood can easily replicate this effect.

Various Echinodorus sword plants fill out the tank, and floating plants are utilized on the surface.

It’s important to double-check the specific Echinodorus plants you choose, as some larger sword plants are too big for a betta tank.

Stick to something like Echinodorus Aquartica, which is smaller but still has distinctive leaves and color.

This next betta tank setup features a single, central island concept thats growing in popularity within the betta-keeping community.

Peter has skillfully used a few rocks to form the base of the main feature, which can easily be replicated in your tank using river pebbles or other inexpensive rocks.

Larger epiphyte plants work perfectly as the central plant in this type of betta tank design.

Anubias barteri, coffeifolia, or caladiifolia are all suitable options depending on the size of your tank, with regular java fern and java fern latifolia being good alternatives.

If you choose to add substrate, several types of Echinodorus can also work, but ensure you apply enough substrate to support the plants’ root structure.

Betta Fish Tank Ideas By Cheerfulbirdlady

Next up we have some betta tank designs from @cheerfulbirdlady who shares photographs and videos of her tanks on her Instagram and TikTok page.

She covers a huge range of styles that range from beginner-friendly tank setups all the way through to some advanced aquascapes so her socials are worth checking out.

Just like the other featured tank ideas in this article, I have chosen what I feel are the best options for anyone looking to keep a betta fish in their aquarium.

I love this betta fish tank setup because it maximizes the use of color with various plants, substrate, and driftwood.

Cheerfulbirdlady blends driftwood and red plants as the tank’s central feature, making them pop by surrounding them with green plants in the sides, midground, and foreground.

Ludwigia Mini Super Red is an excellent and easy-to-grow red plant for creating a similar betta tank, complemented by various green plants.

You can also use Red Root Floaters as your floating plant of choice to add extra red to the setup with minimal effort.

Additionally, small epiphyte plants can be anchored to the driftwood to introduce more greens and other hues with small anubias variants or reds/browns with bucephalandra.

This next tank setup uses an Asian river biotope style that mimics the natural habitat of a betta fish. It’s surprisingly easy to create, given how impressive it looks if you’re into biotopes.

I love the emergent plants rising from the tank’s surface and the lucky bamboo in the back right, which helps manage water parameters to keep your betta fish safe and healthy.

While a strict biotope would use driftwood and rocks naturally found in Thailand, many people use what they have available. There are plenty of affordable options to keep costs down.

Once your hardscape is set, you can add epiphyte plants. Smaller anubias and bucephalandra variants are perfect for detailing the hardscape in this betta tank setup and usually thrive in low-tech tanks.

Depending on your preference, you can use one of the following stem plants toward the back right of the tank:

Most types of Pothos also work well as emergent plants on the left side of the tank, and betta fish love to hang out in the roots, “hunting” for their next meal.

This next tank follows a similar design to the first one by cheerfulbirdlady, using driftwood and red plants as the main focal points, with green plants providing a striking contrast.

For the main red stem plant in the rear, you can use something like Ludwigia Mini Super Red, and for a supporting off-green plant on the rear right, Rotala Orange Juice works well.

Smaller anubias variants are ideal for the green plants on the driftwood, creating a beautiful green contrast throughout the midground of the betta tank and keeping the setup simple.

Rotala Green is an excellent choice for the foreground, but it will require regular trimming. Other green plants can also work well.

Red Root Floaters are likely the best option for a floating plant in this type of betta tank setup. They will eventually turn red, adding even more color to the tank.

Betta Tank Ideas By Bettasandfriends

She stocks her tanks with a wide range of fish but I will be focusing on her betta friendly tanks for this article to try and offer you some inspiration for your new betta tank.

This first tank features a lush, heavily planted aquascape that is ideal for a betta fish.

It’s important to note that achieving this level of plant growth can be challenging without CO2, making it difficult to replicate in a low-tech tank.

The hardscape includes rocks and driftwood, but you can use more affordable options like bogwood and seiryu stone to keep costs down.

Different stem plants are recommended to fill out the planted area with diverse colors, textures, and leaf shapes.

Creating a carpet effect will be challenging without CO2; however, low-tech tanks can use java moss on the rocks for a similar look.

Negative space is crucial in this type of tank, and Sarah has expertly left the front left corner open to contrast with the densely planted areas, ensuring plenty of swim space for the betta fish.

This next betta tank setup showcases a lush, heavily planted green aquascape, which is perfect for creating a stunning contrast with the vibrant red or orange of many betta fish.

While there is a small amount of red plant usage in the center background, most plants are thriving green stem plants.

Driftwood adds texture contrast and a pop of dark color, with bogwood being an excellent, cost-effective choice for this design.

Depending on the plants you choose, you can achieve great results without CO2, making this setup beginner-friendly and easy to maintain.
