Many people like to raise betta fish because of their stunning colors.   Betta fish are also referred to as the Siamese Fighting Fish.  They tend to be very aggressive.  

Since this is the case, you will need to be careful when you raise these fish with others.  They are known to kill other fish.  This is especially true for the male betta fish.  

You shouldn’t even raise male betta fish together.  Females on the other hand can be raised together.

However, a 10-gallon tank is very small.  So, how many female bettas should be in a 10-gallon tank?  Keep reading now to find out!

Raising Female Betta Fish Together

Betta fish originally come from Asia.  Many of the bettas we buy in America are imported from Thailand.  They are known for having large betta fish farms for export.  

Typically, they survive in bodies of water in rivers, ponds, or swamps.  

Since they come from Asia, they are considered tropical fish.  This means they like warm water!  They can’t survive in cold waters.  

If you live in a cold climate, be prepared to use a water heater to raise the tank temperature.  

If you want to use a 10-gallon tank, you probably do not have a lot of room for a fish tank.  While it is possible to raise betta fish in a small tank, it is always better to give them the most room you can.  Simply put, the more room fish have to swim around, the happier they will be.

Bettas especially are known to be energetic fish.  This means they love to swim around.  If they do not have a lot of space, they cannot use all their energy.

Also, a small tank gets dirtier faster. If you need to have a 10-gallon tank,  be prepared to clean it out frequently.  That being said, betta fish are not very big.  

This is the reason you can raise more than one betta in a 10-gallon tank.  On average, you can keep between 3-5 female betta fish in a 10-gallon tank.  Anything more than that will risk the death of your fish.

It is crucial that you only keep female betta fish in the same tank.  Male betta fish will attack each other when they are raised together.

Is It Possible To Have Too Many Fish In The Same Tank?

Every tank has a capacity.  As soon as you start to overcrowd the tank, you pose a threat to your fish’s life.  

Since they are such aggressive fish, it is best not to raise other fish in the same tank.  If you really want to put another creature in your tank with the betta fish, you can go with snails.  

Snails move very slowly and are peaceful.  Their presence does not agitate betta fish.  To ensure that the snail doesn’t get eaten, try to use a big snail.

The other benefit of having snails in your tank is that they help keep the tank clean by eating algae and excess debris.

It is important to note that female bettas can sometimes get aggressive with each other.  Although this is uncommon, it can happen.  

According to the National Library of Medicine, “Ethological studies of female Bettas have revealed aggressive interactions that qualitatively parallel those between male Bettas” This means that if a female is triggered, it can really hurt other fish. 

This mainly happens when one female thinks that they are superior to the other fish in the tank.  They will display territorial behaviors to assert themselves.  

One of the best ways to limit this aggressive behavior is to limit the amount of fish that you put in the tank.  The more fish you have, the higher the chance that aggressive behaviors will come out. 

In Conclusion – How Many Female Bettas Should Be in a 10-Gallon Tank?

It is very possible to have too many fish in the tank.  Stick to keeping a maximum of 5 betta females in a 10-gallon tank.  

If you stay within this number, you should not have much competition between the fish.  

Now you should understand how many female bettas should be in a 10-gallon tank.  Since it is not a big tank, you need to keep the numbers low.  

As long as you do this, you should have success raising female bettas.
