Bettas are not the most sociable of fish, but that doesn’t mean you can’t house them together. You can even keep betta sororities together if you introduce them correctly and monitor their behaviour closely. If you follow these steps, it is possible to keep a female betta sorority in one tank and avoid any aggressive behaviour from the girls. It’s important to note that this setup isn’t suitable for male bettas; they are too aggressive with one another. Here we explain everything you need to know about keeping a female betta sorority.

What is a Betta Sorority?

The word ’sorority’ means a group of sisters’. When fish keepers talk about a Betta sorority, they are talking about a group of female Bettas living together in one tank. A sorority is most commonly formed when you house a few female bettas together. As they get to know each other, they become less aggressive and less territorial. A sorority of Bettas is also known as a ‘Betta colony’. A colony is just a group of fish kept together in one tank.

Why Keep Female Bettas Together?

There are many reasons why you might want to keep your female Bettas together. For example, you may want to breed your fish, or you may have a sick betta in your tank that needs a friend to keep her company. You may also want to keep your betta sorority together because you don’t have the space for multiple tanks. 

If that’s the case, you’ll need to keep an eye on the behaviour of your fish and be prepared to separate them if aggression occurs. Bettas are notoriously territorial, so only keep them together if you are prepared to closely monitor their behaviour. If you have multiple female Bettas in one tank, you may find that they breed amongst themselves. There is no guarantee that they will breed together though, so keep this in mind if you want to breed your fish.

How to Setup a Betta Sorority

When setting up your betta sorority, there are a few things you will want to consider. Firstly, you will want to select a large tank that is at least 10 gallons in size. A 10-gallon tank is far too small for a Betta sorority. Bettas need a lot of space, so don’t try to cram them into a tiny tank. If your bettas are crammed together in a tiny space, they will become even more territorial, and more aggressive towards one another. A large tank will also help to dilute the amount of waste your fish produce. It is also important to select a tank that is sturdy and easy to clean.

Bettas are messy fish, so you will want a tank with a built-in filtration system that can handle the waste your fish produce. You will also want to make sure your tank is well-lit and decorated with plenty of hiding spots and places to swim. If you plan on breeding your fish, you will want to purchase a breeding tank as well. Breeding tanks are generally a little larger than 10 gallons and are relatively inexpensive if you already own a tank that is large enough.

Tips for Monitoring your Betta Sorority

Now that you have your betta sorority up and running, it is time to start monitoring the behaviour of your fish. Unfortunately, bettas are not particularly social fish, and it is rare for them to live together in harmony. You will have to keep an eye on your fish and make sure that no aggressive behaviour is occurring. If aggression does occur, you will need to separate the fish. If your bettas are being aggressive towards one another, there are a few things you can do to help reduce the aggression.

Firstly, make sure you are feeding your fish the correct amount of food. Overfeeding your fish can lead to aggression, so make sure you are feeding them the correct amount of food. Keep your tank clean as well. Bettas produce a lot of waste, so it is important to clean your tank regularly. You will want to monitor your bettas closely over a few weeks to see if they are getting along. If they are, you can feel confident that they are getting along. You can then add more bettas to your tank in the future.

Problems to be Aware of When Keeping a Betta Sorority Together

As we have mentioned, bettas are not the most social fish. They are notorious for fighting amongst themselves. When keeping a Betta sorority together, you will have to be careful to avoid aggressive behaviour in your fish. If you spot any signs of aggression, you will need to separate your fish and watch them even more closely. Bettas are aggressive fish, but that doesn’t mean it is impossible to keep them together. If you set up your tank correctly, introduce your fish correctly, and monitor their behaviour, you can keep a female Betta sorority in one tank.


As we have mentioned, bettas are not particularly social fish, but that doesn’t mean you can’t keep them together. If you follow the advice in this article and keep a close eye on your bettas, you should be able to successfully keep a Betta sorority in one tank. Now that you know what a Betta sorority is and why you might want to keep your female Bettas together, it’s time to choose a tank and get ready to house your fish. We recommend that you choose a 10-gallon tank, and make sure it is equipped with a filter. Once you have your tank ready, it’s time to select your fish.
