Many aquarists advocate keeping multiple female Betta fish together in what’s called a sorority, as they are supposed to be less aggressive than their male counterparts.
Is this actually true? Can female Bettas cohabit peacefully in aquariums as small as 10 gallons (38 L)? The answer to that question is not straightforward. Sometimes, a betta sorority works very well, whereas other times, it can lead to carnage in your tank!
Read on to learn more about keeping a group of female betta fish.
Key Takeaways
- Betta sororities, the practice of housing multiple female bettas together, can be peaceful but also risk aggression and stress, depending on individual fish temperaments.
- A well-planted tank with hiding places is crucial to reduce stress and prevent fights in a betta sorority, yet injuries and rapid disease transmission can still occur.
- The coexistence of male and female bettas is not typically advised unless for breeding, and even then, close monitoring is necessary to prevent aggression.
What Is a Betta Sorority?
A betta sorority is simply the name given to a group of female betta fish living together in the same tank.
How Many Female Bettas Can Live In a Sorority
You can have as many female betta fish in your sorority as you want, provided you have plenty of space for them. That said, we recommend keeping less than ten individuals in a group.
Do Female Bettas Fight
When kept together, female bettas sometimes engage in minor disputes, although they typically coexist peacefully, as long as one fish is not overtly aggressive.
Each betta fish has its unique personality, with some being combative and others being mellow. However, I’ve kept betta sororities successfully with no major fighting or problems with aggression or bullying.
The key to keeping your ladies happy and harmonious is to provide them with a big enough fish tank, filled with plenty of dense planting, caves, and other decorations. That gives the fish somewhere to retreat if they feel stressed and helps to prevent squabbles over territory.
Potential Problems in a Betta Sorority
Unfortunately, there are a few issues that can affect the well-being of a Betta sorority.
Stress
Bettas are constantly stressed. Many Betta sorority keepers claim that their fish never attack each other or that they rarely flare. Unfortunately, what they fail to realize is that such submissiveness is another form of excessive stress.
Also, keep in mind that while horizontal stress stripes are easy to see in some Bettas, they’re not in others because of their colors, so don’t assume that lack of stress stripes means everything is going well! For example, stress stripes are really visible on blue and red Bettas but not on yellow or white. There are tons of other signs to watch out for as well, such as clamped fins, quick breathing, darting, lack of appetite, and hiding.
Diseases and Illnesses Spread Faster
When any fish species is kept under stressful circumstances, their immune systems take a hit. In a Betta sorority, illnesses can spread like wildfire and take out an entire fish tank. It’s not uncommon to lose groups to parasites, which take advantage of compromised fish. Not only do the fish suffer, but you’ll be stressed, too, as you try to remedy emergencies.
Injuries
It’s not uncommon to see torn fins and missing scales within a Betta sorority. Open sores leave fish susceptible to bacterial diseases, and injuries to fins can make swimming difficult.
Aggression
Male betta fish are notoriously aggressive and territorial, which is why you must never keep two males together. Unfortunately, some female betta fish are feisty, and bullying by one dominant female is often an issue in a sorority.
Wild betta fish or Plakats tend to be more aggressive than the Betta splendens that you generally find for sale in fish stores. So, if you want to keep a few females in a sorority, I would always go for the Betta splendens variety.
Can I Keep a Male Betta With a Sorority?
In theory, you can keep a male Betta with a group of females. However, I would only do that if I wanted to encourage the fish to breed. Even then, male Betta fish can sometimes be aggressive towards females, so you must keep a close eye on the behavior and be prepared to separate the sexes if fighting breaks out.
Final Thoughts
There are many different schools of thought when it comes to keeping a betta fish sorority. Some aquarists maintain that you can safely and successfully house groups of female bettas in a large tank, whereas other hobbyists tell tales of bullying, fighting, and death.
However, if you want to keep a few female bettas and one male with the idea of encouraging the fish to breed, be sure to provide the fish with a large tank, plenty of hiding places, and shelter, and be prepared to separate the fish if aggression is an issue.
