Keeping Betta Fish Together – A Complete Guide to Cohabitation

Betta fish are one of the most sought after species in the aquarium trade. These beautiful fish, also known as Siamese fighting fish, are popular for their vibrant colors and feisty personalities.

However, keeping bettas together can be a tricky affair if you’re not sure what you’re doing. In this article, we will discuss the differences between male and female betta fish and how to keep them together safely.

We will also look at the benefits and risks of creating a betta sorority or keeping male bettas together.

Female Betta Fish Sorority Tanks

Betta fish sorority tanks are becoming increasingly popular in the aquarium hobby. These tanks consist of a group of female bettas living together in a community.

However, before considering a sorority tank, it’s essential to understand the nature of female betta fish.

Female Betta Fish Temperament

Female betta fish, like their male counterparts, can be quite territorial. However, female bettas are less aggressive than males, making them more tolerant of other bettas in their tank.

It’s essential to remember that each betta has its own unique personality and behavior.

Setting Up a Betta Sorority Aquarium

When setting up a betta sorority aquarium, several factors need to be considered to ensure the tank’s success. These include the aquarium’s size, plants, decorations, filter, temperature, feeding, and water quality.

Aquarium Size

A minimum of 10 gallons is recommended for a betta sorority tank. This size will provide enough space for the female bettas to establish their territory while reducing the number of aggressive interactions.

A larger tank is always better and will provide more options for landscape and additional fish.

Plants and Decorations

Live plants, driftwood, rocks, and other hiding places can help break up the line of sight between the female bettas, reducing aggression and stress. In addition, aquarium decorations create suitable spaces for breeding, which improves the overall health of the tank inhabitants.

Filter and Water Quality

Betta fish require high water quality, and a proper filtration system is vital for maintaining optimal water conditions. It’s essential to perform regular water changes, with water temperature around 75F to 80F to ensure the female bettas are healthy.

Male Betta Fish Cannot be Kept Together

While female bettas can sometimes be kept together, it is well known that male bettas cannot. Male betta fish’s aggressive nature makes it almost impossible to keep more than one male in the same tank.

Male Betta Fish Temperament

Male betta fish are known for their hot-tempered behavior, which makes them ideal for solo living. Bettas are territorial fish that will aggressively defend their area.

Males, in particular, are known to fight to the death with each other, making it crucial to avoid keeping them together.

Risks of Keeping Male Bettas Together

There are several risks associated with keeping male bettas together, including injury, stress, and death. Fights between male bettas can cause severe damage to each other, leading to injuries that are often fatal.

In addition, surviving bettas may develop stress-induced diseases, such as fin rot or fungal infections.


As we have discussed in this article, the success of keeping female bettas together depends on your proper care and the setup of their environment. Ensuring high water quality, the proper aquarium size, and hiding spaces are keys to a healthy sorority tank.

However, male bettas cannot be kept together due to their aggressive nature. We hope this guide has provided valuable information to help you determine the best approach when keeping betta fish.

Remember, keeping your aquarium well-maintained with the appropriate conditions is essential for the health and well-being of your bettas.

3) Female Betta Sorority Tank Setup

Betta sorority tanks are a popular choice among aquarists who want to keep multiple betta fish in a single tank. Female bettas can live together peacefully, but certain precautions need to be taken to ensure their health and happiness.

In this guide, we will cover everything you need to know about setting up a female betta sorority tank.

Tank Size and Aquascaping

The size of the aquarium is essential when setting up a female betta sorority tank. The minimum recommended size is 10 gallons, although larger tanks are always better.

Larger tanks provide more swimming space and reduce aggression between the female bettas. The aquarium should be planted and decorated with various hiding places such as caves, driftwood, and rocks.

The decor creates separate areas within the tank, which reduces aggressive behavior and stress among the female bettas.

Choosing Compatible Female Betta Fish

It’s essential to choose compatible female bettas when setting up a sorority tank. The females should be the same size and age to prevent dominance from one fish over another.

Avoid adding smaller or weaker fish as they may become targets for bullies. Acclimating the new fish to the environment is important as well;; when adding the female bettas, it’s essential to let them acclimate to the new environment in a separate container for a few hours before moving them into the main tank.

It helps to lower the stress level of the fish.

Adding the Female Bettas Together

When adding the female bettas together, it’s crucial to understand the pecking order and be prepared to separate any aggressive fish. The females may have to establish a hierarchy among themselves, which may cause some chasing and nipping, but this is somewhat normal and acceptable in the initial stages.

In rare cases, a particular fish may become too aggressive towards the others, in which case removal from the tank must be immediate. Introducing the female bettas into the tank simultaneously is the ideal way to establish the hierarchy.

Feeding Female Betta Fish

Feeding female betta fish is essential for their health and well-being. They are carnivorous fish and require a high protein diet consisting of pellets or live food.

Feed them twice a day and only what can be consumed in a few minutes. Overfeeding can lead to bloating, constipation, and other health issues, leading to an unbalanced environment in the tank and ammonia spikes.

Water Quality and Maintenance

Maintaining the water quality in a betta sorority tank is crucial. A good biological filter is necessary to ensure optimal water conditions, and the filter should be cleaned every month.

Cleaning the substrate or vacuuming is also important during cleaning. Perform weekly water changes of 20 to 40% of the water volume while keeping an eye on the water parameters like pH, ammonia, nitrite, and nitrate levels.

Regular testing is essential to prevent water quality deteriorating, which can lead to a variety of health problems for your bettas.


Setting up a female betta sorority tank requires careful planning and preparation. A well-maintained and planted tank with a variety of hiding places enables compatibility among the female bettas, good feeding habits, and proper water quality maintenance.

Keeping these factors in mind throughout the process of setting up a female betta sorority tank ensures that the fish remain healthy and happy in their shared environment. The beauty of a female betta sorority tank is a stunning and passive show tank where they can display their bright colors and happy behavior.

In conclusion, setting up a female betta sorority tank requires careful planning and consideration for the safety and health of the fish. Factors such as tank size, aquascaping, finding compatible female bettas, feeding habits, and water quality maintenance are essential to ensure the fish remain healthy and happy in their shared environment.
