Are Female Bettas Aggressive to Each Other?

In their natural habitat, female bettas establish a pecking order within their group, and this hierarchy can carry over into a domestic aquarium setting.

It is recommended to keep female bettas in groups of four or more to help spread out any aggression and reduce the chances of one particular fish being targeted.

When introducing new female bettas to the tank, it is essential to monitor their interactions, as territorial disputes can arise carefully.

Plenty of hiding spaces and aquatic plants can help alleviate tension and provide escape routes for any fish feeling threatened.

It is important to remember that each betta fish has its unique personality, and while some female betta may be relatively peaceful, others may be more territorial. 

Proper research, observation, and tank setup are crucial when keeping female bettas to ensure a harmonious living environment. 

Why Do Betta Fish Fight?

Betta, or Siamese fighting fish, are known for their aggressive nature, especially towards other male bettas. This aggression stems from their territorial solid instincts rooted in their natural habitat and evolutionary history.

Here are some of the reasons why betta fish fight:

  • Territory: In the wild, betta fish live in shallow rice paddies and waterways with dense vegetation. These areas provide them with shelter and hunting grounds, which they fiercely defend from other males. When two male bettas encounter each other in confined spaces, such as an aquarium, they see each other as intruders and will fight to establish dominance. 
  • Breeding: Betta fish are sexually dimorphic, meaning that males and females have different physical characteristics. Male bettas are larger and more colorful than females, using their vibrant fins to attract mates. During the breeding season, males will compete for the attention of females and fight off any rivals who come near their bubble nests, where they fertilize the eggs. 
  • Stress: Betta fish can become stressed for various reasons, including overcrowding, poor water quality, and inadequate hiding places. Stress can lower their immune system and make them more likely to lash out at other fish. 

When two betta fish fight, they typically display aggressive behaviors such as flaring their gills, spreading their fins, biting, or nipping at each other’s tails and fins. In severe cases, the fighting can lead to serious injuries or even death.

Similarities Between a Male Betta Fish and a Female Betta

Despite their distinct appearances, male and female betta fish share surprisingly many similarities. Here are some of the key ones:

Basic biology:

  • Both sexes are members of the same species, Betta splendens, and share the same basic body structure and physiology.
  • They have the same lifespan, typically around 3-5 years, with proper care.
  • Both males and females are obligate air breathers, meaning they must take gulps of air from the water’s surface to survive.


  • Both sexes exhibit territorial behavior and will defend their space against other fish. However, males are generally more aggressive, especially towards other males.
  • Both can exhibit vertical stripes and flare their gills and fins to appear larger and more intimidating when threatened.
  • Both can build bubble nests, although males are more likely to do so for breeding purposes.


  • Both are carnivorous and have similar dietary needs, primarily feeding on insect larvae, bloodworms, brine shrimp, and other small invertebrates.

Care requirements:

  • Both require similar water conditions, including a temperature range of 75-80°F (24-27°C) and a pH of 6.5-7.5.
  • They also need similar tank sizes, with a minimum of 5 gallon tank for a single betta.

Physical features:

  • While males have much longer and more flowing fins, both sexes have the same basic fin structure, including dorsal, anal, pelvic, and caudal fins.
  • Both have the same iridescent scales that can shimmer with different colors depending on the light.

Here are some additional similarities to keep in mind:

  • Both sexes can be bred in captivity, although the breeding process for males is more complex.
  • Both are susceptible to the same diseases and health problems.
  • Both can make fascinating and rewarding aquarium pets with proper care.

While their physical differences are striking, male and female betta fish share many underlying similarities, making them both fascinating creatures.

Should I get a male or female Betta fish?

When deciding whether to get a male or female Betta fish, there are a few factors to consider. Male Betta fish are known for their vibrant coloration and long, flowing fins, making them visually stunning. They are also known for their aggressive behavior, particularly towards other male Betta fish.

Betta Fish Sorority Tank

On the other hand, female Betta fish are generally less colorful and have shorter fins, but they are naturally less aggressive. They can often be kept with other female Betta fish in a community tank.

Ultimately, deciding between a male or female Betta fish depends on your preference and what you want out of your fish. A male Betta fish may be better if you are looking for a visually stunning centerpiece fish in a solo tank.

A female Betta fish may be the better option to create a peaceful community tank with multiple fish. Consider your tank setup, your other fish species, and your preferences before making a decision. 

The Benefits of Female Bettas Sorority Living:

While male bettas are notorious for their aggressive territoriality, females can sometimes live together peacefully in a carefully managed aquarium called a sorority tank. This can offer several advantages for both the fish and the aquarium.

Benefits for the fish:

  • Social interaction: Female bettas are naturally social creatures, and living in a sorority can provide them with much-needed interaction and stimulation. They may even engage in playful behavior, such as chasing each other or fin flaring.
  • Reduced stress: Living alone in a small tank can be stressful for bettas. A sorority group of female bettas can help to distribute the stress among multiple fish, making it easier for each individual to cope.
  • Variety and beauty: A sorority tank can be a stunning display of color and finnage, as female bettas come in various colors, patterns, and fin types.

Benefits for the aquarist:

  • Space efficiency: A sorority tank can be an excellent way to keep multiple bettas in a relatively small space. This can be especially appealing for aquarists with limited space.
  • Visual interest: A well-maintained sorority tank can be a beautiful and captivating addition to any home.
  • Challenge and reward: Successfully maintaining a sorority tank can be a challenging but rewarding experience for experienced aquarists.

Things to keep in mind:

  • Not all female bettas are suitable for sorority living. Some bettas are too aggressive to live peacefully with others. It is essential to carefully select your fish and be prepared to remove any fish cannot be compatible.
  • A sorority tank requires a large, well-decorated aquarium. The tank should be at least 20 gallons per Betta and heavily planted with plenty of hiding caves.
  • Maintaining good water quality is essential for a healthy sorority. Regular water changes and a good filtration system are necessary to prevent stress and disease.

Overall, female betta sorority living can be a rewarding experience for both the fish and the aquarist. However, doing your research and being prepared for the challenges is essential.
