If you’ve always wanted to keep more than one Betta, then you may have asked yourself this question before:

Can two female Betta fish live together? 

The answer is yes, but there are some things you need to keep in mind if you want to try this.

In this blog post, we will discuss the pros and cons of keeping two female Betta fish together, and we will also give you some tips on how to make it work if you decide to go ahead with it.

Why It’s Okay To Have Female Bettas In The Same Aquarium

The reason is that female Betta are not aggressive fish, and they can live in the same habitat without any problems.

If you have more than one female Betta fish in your aquarium, they will likely form a “sorority” together.

The Pros Of Keeping Two Female Betta Fish Together

There are several advantages to keeping two female Betta fish together.

One of the biggest advantages is that if you have more than one female Bettas, they will form a “sorority” and swim around your aquarium as though it were their territory or home.

This can help reduce aggression between females because there won’t be any dominant males.

The Cons Of Keeping Two Female Betta Fish Together

There are a few disadvantages to keeping two female Betta fish together, but they are minor compared to the pros.

It is possible that some females will show some aggression and try to become the dominant female. However, with plenty of hiding places and tank mates, this is easily resolved.

One disadvantage is that you will need to provide more food for both fish because they will be eating from the same food source.

Another disadvantage is that if one of your female Bettas dies, the other one may become depressed and stop eating.

Will Female Bettas Fight?

It’s not uncommon for female Bettas to fight, but it happens far less than male Bettas. If you see your Betta Fish Flaring at one another it’s a good sign they might not be happy with each other.

If you want your fish to live together peacefully, then there are a few things you should do before putting them into the tank.

  2. Tank Size: Make sure the tank is large enough to accommodate all of your fish (at least five gallons per fish). Learn more about the minimum tank size for Betta fish.
  3. Live Plants: Provide plenty of plants and hiding spots for your fish.
  4. Water Quality: Use a filter and heater to keep the water temperature stable in the aquarium.

List Of Good Tank Mates For Female Betta Fish

If you’re not sure if keeping two female Betta fish together is the right decision for you, or if you want to have some other options, here are some good tank mates for female Bettas:

  • Nerite snails.

Here is an even bigger list of fish that can live with your Bettas.

Introducing New Fish To Your Female Betta?

It’s essential to introduce new fish slowly so that your female Betta has time to adjust.

The best way is by keeping them in a separate tank for at least one week before adding them into the main tank with other Bettas.

How To Determine If Your Betta Fish Are Male or Female

If you’re unsure if the Bettas you have are male or female, there are a few ways to determine this.


One way is by looking at their fins. Male Bettas will have long, flowing fins, while female bettas’ fins will be shorter and more rounded.

Body Shape

Another way is to look at their body shape.

Keep in mind that males tend to be larger than females, but this isn’t always the case, so it’s better not to rely on size alone when determining gender.

Color Patterns and Scales

Even though color can vary from one Betta fish to another, there are some general differences between males and females regarding colors patterning scales.

Female Bettas usually have more muted colors, while male Betta fish display bright, colorful patterns (usually reds/oranges).

Male Bettas also have thicker lips with a fuller mouth area than female counterparts, which are completely thinner or lacking in lip structure!

Behavioral Differences Between Male And Female Betta Fish

There are also some behavioral differences between male and female Betta fish.

Males are more aggressive than females and will often fight for territory and dominance.

On the other hand, females tend to be more social and can live together peacefully if they’re introduced correctly.

Bubble Nests

Male Bettas are also known for their bubble nests. So if you see a bubble nest in your tank, it’s a male Betta!


Male Bettas also have a beard-like structure on their head called the operculum, while female Bettas don’t.

Frequently Asked Questions:

Here are a few stocking guidelines;

  • 3 Gallon Tank: In a three-gallon tank, it’s possible to have two female Betta fish.
  • 5 Gallon Tank: In a five-gallon tank, it’s possible to have two male Betta fish.
