10 Betta Sorority Tank Mates To Try In Your Aquarium!

Betta sorority tanks are an innovative and attractive way to house multiple female betta fish together. These tanks attempt to provide a harmonious environment for the bettas but it can be a challenging project, especially if you are new to the fish keeping hobby.

Unlike male bettas, female bettas are far less aggressive, making sorority tanks a popular project for aquarists looking to display a stunning collection of these captivating fish.

Over the last few years, there has been a steadily growing trend in people keeping other species of fish in their tanks with their bettas. This has resulted in a spike in the number of people reaching out and asking questions about betta sorority tank mates so we decided to publish this article to try and help as many of our readers as possible.

Should You Add Tank Mates To A Betta Sorority Tank?

Just because you can add tank mates to a betta sorority tank doesn’t necessarily mean you should. Betta sorority tanks can be difficult to maintain even for experienced fish keepers, and adding non-betta tank mates only complicates matters further.

A crucial factor when considering tank mates for a betta sorority is the size of the tank. A minimum of 50 gallons is recommended to provide ample space for the bettas and their potential tank mates. We know that you can technically setup a far smaller betta sorority tank and experienced betta keepers can do it in 20-30 gallon tanks but the majority of our readers are beginners.

Additionally, the tank should have plenty of hiding spots, consisting of live or fake plants, rocks, and driftwood. These hiding spots play a vital role in reducing aggression among the inhabitants.

Maintaining suitable water parameters is essential to minimize aggression and ensure the well-being of the bettas.

As we covered in our betta fish care guide, we recommend you stick to the following water parameters for your betta sorority tank:

  • Water Temperature: 78-80°F
  • Water Flow: Still-Low
  • pH: 6.8-7.5
  • GH: 3-4 dGH
  • KH: 3-5 dKH
  • Ammonia: 0 ppm
  • Nitrite: 0 ppm
  • Nitrate: <20 ppm

Maintaining consistent water parameters for your female bettas can help to reduce the chances of them being aggressive towards their tank mates.

While choosing tank mates for a betta sorority, it’s important to select fish species that can thrive in the same water parameters as bettas. Peaceful, small, and active fish that won’t compete with bettas for food or territory are generally good choices.

In conclusion, adding tank mates to a betta sorority tank is feasible but may be challenging due to the need to maintain suitable water parameters, provide sufficient space and hiding spots, and choose compatible species. Prioritize the bettas’ well-being and only consider introducing tank mates if you feel confident in your ability to manage the complexities that may arise.

Additional female betta fish are a great addition to a sorority tank, as they can coexist peacefully with one another when given the proper environment. Introducing more female betta fish with various colors, patterns, and tail shapes can enhance the visual appeal of the tank while keeping maintenance straightforward.

We know that this first suggestion may sound a little strange but sticking with female betta fish usually helps to keep things simple, especially for beginners.

It is usually far easier to keep two female betta fish together in the same tank than to integrate other species, especially if your tank is small and cramped.

Betta fish have a huge range of colors, patterns, and tail/fin shapes that allow you to get a huge range of variety in your tank without having to add any additional species. Keep in mind, many of the other fish that can work in a betta sorority tank are schooling fish and usually need at least six fish to school where a single betta female can work.

When selecting female bettas for your sorority, consider their personalities as well as their appearances. Look for fish with calm and non-aggressive temperaments to avoid conflicts within the tank.

In conclusion, adding a variety of female betta fish to your sorority tank can make it a lively, colorful, and visually appealing environment. Just remember to provide a spacious, well-decorated tank and select fish with compatible temperaments to maintain peace and harmony among your aquatic pets.

Aquatic snails can be great tank mates and clean-up crew members for a betta sorority. Their lack of color and slow movement reduces the chance of bettas paying attention to them, making them excellent companions in a betta sorority tank.

Furthermore, snails are resilient. If a betta does happen to find a snail, they typically just retract into their shell for safety until the betta fish goes away. This low-stress interaction allows the snails to comfortably coexist with bettas.

Various types of snails can be compatible with betta sorority tanks:

  • Mystery Snails: With a water pH of 7.0-7.5 and water temperatures of 68-82 degrees Fahrenheit, they are a suitable option for betta tanks.
  • Nerite Snails: Known for their effectiveness in algae control and adaptable nature, they make great tank mates for bettas.
  • Assassin Snails: Though their primary diet is other snails, they can coexist with bettas, but it’s vital to monitor their behavior and diet in the tank.
  • Japanese Trapdoor Snails: Their peaceful and hardy nature makes them ideal tank mates for bettas.
  • Malaysian Trumpet Snails: Due to their ability to burrow in the substrate and clean the tank, these snails contribute to maintaining a healthy betta sorority tank.

Some snails can reproduce at a rapid pace so you have to keep an eye on the snail population in your tank as people often have problems such as turbo snail poop building up in their tank.

This is why some people keep one assassin snail in their tank with a number of mystery or nerite snails as a form of population control.

When selecting aquatic snails as tank mates for a betta sorority, ensure the chosen species are compatible with betta fish in terms of water temperature, pH levels, and temperament. With the right combination, aquatic snails can contribute to a thriving and vibrant betta sorority tank.

Corydoras Catfish

Corydoras Catfish are considered an ideal tank mate for betta sorority tanks due to their peaceful temperament and compatibility with bettas. They are bottom dwellers, meaning they occupy a different area of the tank compared to bettas which are usually closer to the top or middle of the tank.

This can be enough to help reduce the chances of there being any aggression between the two species helping keep your betta sorority tank as harmonious as possible.

These catfish are not only easy to care for but also known for their hardy nature, making them suitable for both beginners and experienced aquarium enthusiasts. When setting up a betta sorority tank with Corydoras, it’s essential to provide a suitable substrate to meet their natural foraging behavior.

One important aspect of maintaining a healthy betta sorority tank that includes Corydoras catfish is ensuring their dietary needs are met. While bettas thrive on a protein-rich diet, Corydoras require a balanced diet that includes vegetables, sinking pellets, and live or frozen foods.

Moreover, the water parameters for bettas and Corydoras catfish are compatible, further increasing their potential as tank mates. Both species do well in slightly acidic to neutral water, with a pH of around 6.0 to 7.5. They also both prefer stable water temperatures in the range of 72-78°F (22-26°C). Maintaining these water conditions can ensure the happiness and longevity of your betta sorority and their Corydoras catfish companions.

By carefully considering the needs and compatibility of Corydoras catfish with betta sorority tanks, you increase the likelihood of creating a harmonious and healthy aquatic environment. Following these recommendations will allow you to enjoy an engaging, diverse, and thriving betta sorority tank with Corydoras catfish as ideal tank mates.

Shrimp can be an excellent addition to a betta sorority tank, as they can coexist with betta fish and assist in controlling algae growth. Most types of shrimp can work well in a betta tank with neocaridina shrimp usually being our default recommendation.

This is due to the bright colors of neocaridina shrimp popping well in the betta sorority tank helping to add more color. Here are some popular neocaridina shrimp to give you an idea of the options available.

Different types of shrimp for aquariums

If you are a beginner, we would recommend that you opt to keep cherry shrimp in your betta sorority tank as they are cheap, hardy, and easy to find in most local fish stores.

It is important to note that in a betta sorority, some shrimp may become casualties. To replace any lost shrimp, many aquarists opt to maintain a small 1-gallon shrimp breeder tank. This helps ensure a continuous supply of shrimp for the main tank, keeping the betta sorority environment clean and thriving.

When incorporating shrimp into a betta sorority, make sure to provide hiding spots for them to retreat, particularly for the smaller species like Cherry shrimp. Plants, rocks, and other tank decorations can serve as hiding places to reduce shrimp stress and offer a more balanced tank environment.

In conclusion, adding shrimp to a betta sorority tank can be beneficial for both the bettas and the tank’s health. By selecting compatible shrimp species and managing the shrimp population, you can create a clean and visually appealing aquatic environment for your bettas to thrive in.

Kuhli Loaches can work surprisingly well as tank mates for a betta sorority tank that has been set up correctly. These peaceful, nocturnal bottom dwellers enjoy the company of other kuhli loaches and appreciate all the hiding spots that a sorority tank typically provides.

Their shy nature allows them to keep to themselves, reducing the chances of conflicts with the bettas.

It’s important to ensure that the tank environment is suitable for both bettas and kuhli loaches. They thrive in tropical temperatures and similar water conditions. Keep the water temperature between 75°F and 82°F, with a pH level from 6.0 to 7.5. Kuhli loaches also prefer a well-planted tank with a soft sand substrate as they love to burrow in the sand to hide.

Kuhli loaches also appreciate caves, tubes, or hiding spots made from driftwood or rocks. Providing these features creates an enjoyable environment for them, as well as the bettas. Furthermore, kuhli loaches are nocturnal creatures and will venture out at night to scavenge for food. So, make sure to provide them with appropriate food, such as sinking pellets or algae wafers.

To sum up, incorporating kuhli loaches into a betta sorority tank can create a balanced, harmonious aquatic community. As long as the tank is set up correctly, with appropriate hiding spots and water conditions, kuhli loaches and bettas can coexist without issue.

Harlequin Rasboras

Harlequin Rasboras can work as a tank mate in a betta sorority tank, offering visually stunning and harmonious fish community. They are widely known for their peaceful temperament and non-threatening behavior, which makes them a great choice for a betta sorority tank.

To create a comfortable environment for Harlequin Rasboras and bettas, it is generally recommended to keep a minimum of six Harlequin Rasboras in the tank. This encourages them to school and exhibit the dither fish effect, which helps to reduce aggression among the bettas that share the tank with them. Moreover, their schooling nature adds a dynamic aspect to the tank, making it more appealing to watch.

Harlequin Rasboras require a tank that is heavily planted with plenty of hiding spots. This setup not only allows the Rasboras to feel secure but also helps bettas find places to retreat and relax, ultimately lowering stress and potential aggression. Additionally, ensuring adequate swimming space and maintaining stable water parameters is vital to the well-being of both Harlequin Rasboras and bettas.

In conclusion, Harlequin Rasboras can be an excellent addition to a betta sorority tank, providing a visually appealing and peaceful environment for all tank inhabitants. By maintaining a proper tank setup with appropriate schooling numbers and ample hiding spots, hobbyists can successfully combine these species while promoting a harmonious and captivating aquarium.

Ember Tetras are small, peaceful fish that can make excellent tank mates for a betta sorority setup. These brightly colored red and orange fish are known for their peaceful nature and compatibility with other non-territorial fish, making them a great addition to a community tank.

A small school of 6-8 Ember Tetras can work well in a betta sorority, provided the tank is properly sized and set up. It is crucial that the tank is at least 50 gallons or larger, with plenty of hiding spots to reduce territorial aggression.

To further minimize potential conflicts, it is helpful to introduce the Ember Tetras into the tank before adding the betta fish. This ensures that the tetras are in the tank as soon as the betta is added so as far as the betta is concerned, they have always been there and are not a potential threat.

Although ember tetras will use rocks and driftwood as hiding spots, they definitely seem to prefer plants. It doesn’t seem to matter if they are real or fake plants but they definitely seem more confident in tanks that use plants for cover.

In summary, Ember Tetras can be a harmonious choice for betta sorority tank mates, provided the appropriate tank size and environment are established. With conscious planning and attention to their specific requirements, these two species can coexist peacefully in a visually stunning aquarium setup.


Soem guppies swimming in their tank

Guppies are a popular option for many aquarium enthusiasts, known for their vibrant colors and active nature. While they can sometimes be a successful addition to a betta sorority tank, there are a few factors to consider.

Guppies may draw unwanted attention due to their bright tails, potentially causing tension with betta fish. Some aquarium owners, however, have managed to establish harmonious betta sorority tanks with guppies as tank mates.

The success of these tanks may be attributed to the dither-fish effect, a phenomenon where the presence of smaller fish can help diffuse aggression among larger species.

Another aspect to consider is the occasional tendency for guppies to nip at the tails of betta fish. This behavior can lead to stress and health issues for the bettas as well as retaliatory attacks. As we covered in our guppy care guide, you can minimize such occurrences, providing plenty of hiding spaces and maintaining proper water parameters can help keep both species content and calm.

When introducing guppies to a betta sorority tank, it is essential to closely monitor their behavior and interactions. If aggression appears to be an issue, removing the guppies may become necessary for the wellbeing of all tank inhabitants.

In conclusion, guppies can potentially coexist with bettas in a sorority tank, but the outcome may be uncertain and precautions should be taken to ensure a peaceful environment for all species involved.

Bristlenose Plecos

Bristlenose Plecos can be a suitable choice for tank mates in certain betta sorority tank setups, especially if the tank has an appropriate substrate. These plecos are known for being peaceful and generally minding their own business. They tend to ignore betta fish and focus on their own activities, which mostly involves eating algae and scavenging for leftover food.

One thing to consider before introducing a Bristlenose Pleco into your betta sorority tank is the amount of algae available. These plecos are efficient algae eaters and can consume large quantities in a short period of time.

This high consumption of algae leads to increased waste production, as these fish become mini poop machines. As a result, introducing a Bristlenose Pleco to your tank could necessitate more frequent tank maintenance.

It is essential to monitor the interaction between the Bristlenose Pleco and the betta fish in the sorority tank.

While they usually ignore one another, every fish has a unique personality, and individual exceptions may occur. Make sure to provide enough hiding spots and appropriate decorations in the tank to ensure that both the betta fish and the Bristlenose Pleco can comfortably coexist.

In conclusion, Bristlenose Plecos can work well as betta sorority tank mates in certain setups. Their peaceful nature and algae-eating habits can benefit the tank, but remember to consider the extra maintenance that may be required due to their waste production. With the right tank environment and proper consideration, Bristlenose Plecos can make a positive addition to betta sorority tanks.

Neon Tetras

Neon tetras can work as tank mates in a betta sorority, but there are certain considerations to keep in mind. To accommodate neon tetras in a betta sorority tank, you may need to reduce the number of female betta fish. This trade-off might not be ideal for most hobbyists, leading them to opt for other tank mates instead of neon tetras.

A minimum of six neon tetras is required for this setup to work, as they are a shoaling species and need a group for their well-being. Additionally, the tank should be heavily planted to provide ample hiding spaces for these fish, making them feel safe and secure.

To summarize, neon tetras can potentially be introduced to a betta sorority tank, but one should consider the trade-offs, such as the reduction in the number of female betta fish, and the requirements like a minimum of six neon tetras and the need for a heavily planted tank. If these conditions are met, neon tetras can make for a visually impressive and lively addition to your aquarium.
