24 Best Tank Mates for Betta Fish (In 3, 5, and 10 Gallon Tank)

It is very exciting when you get your first betta. But after some time you realize something is missing!

My Betta fish is lonely!

But what are the best tank mates for my betta fish and more importantly which other fish can live in 3, 5 or 10-gallon betta fish tank?

No worries!

I got you covered.

In this blog post, I’m going to show you what fish is compatible with your betta fish no matter what tank size you have.

So let’s get started.

Betta fish has a reputation of a very aggressive fish and it can’t tolerate any other fish (even other bettas) in its tank.

Keeping tank mates with Betta fish is not recommended for beginners because it could be very challenging.

Even if you keep Betta fish with compatible tank mates, it really depends on the behavior of your Betta fish if it can live with them.

Some Betta fish will tolerate other tank mates and others could be very territorial and attack them.

So you will have to test some tank mates listed in this blog post with your Betta fish and see what fish your Betta fish can tolerate.

When it comes to tank mates for Betta fish You should keep the tankmates which are small in size, peaceful and usually stay near the bottom or in the spectrum of the tank where Betta fish usually don’t hang out.

Also, you should avoid keeping fin nippers with your Betta fish.

Do Betta fish really get lonely?

Betta fish really don’t need any other fish in their tank.

They don’t get bored because of the loneliness.

Betta fish may attack other fish but there are some species that you can keep with the betta fish.

But in the end, it all comes down to the behavior of your Betta fish towards other fish.

Other Betta fish as tank mates for your Betta fish?

You can keep other Betta fish as tank mates for your Betta fish.

But there is a caveat to that.

You may have heard that you cannot keep two male Betta fish in the same tank and that is completely true.

If you keep two male Betta fish in the same tank then they will fight with each other until only one remains.

They do so to protect their territory and eggs from the other male.

Can you put male and female Betta fish together?

You can keep male and female Betta fish together temporarily for breeding purposes.

But you cannot keep them together permanently.

If you keep them together permanently then the male will attack the female Betta fish.

While breeding Betta fish, breeders slowly introduce male and female Betta fish.

They put them into the same tank and keep a clear divider between them.

Then they watch their behavior for a few days.

When the male Betta fish builds a bubble nest for the eggs then the breeder removes the divider.

After the eggs are being released by the female Betta fish then the male Betta fish can attack her that’s why breeder keeps them separately after the eggs are laid by the female Betta fish.

Can two female Betta fish live in the same tank?

Female Betta fish usually tolerate each other.

They usually don’t fight with each other if there is a sufficient amount of space in the tank.

If you keep two female Betta fish in a relatively small tank then they will fight with each other.

 3 gallons per female Betta fish is a good starting point and obviously the more space the better.

Can Betta fish live with other types of fish?

There is no single answer to this question.

Betta fish are very aggressive and it really depends on the behavior of your Betta fish.

Basically, you will have to introduce other fish into the Betta fish tank slowly and watch its behavior with the other fish for a couple of days.

Some Betta fish don’t tolerate any other fish in their tank and some will tolerate other tank mates.

There are some things you should keep in mind while selecting tank mates for your Betta fish.

Betta fish tankmates should be peaceful fish that don’t get very big.

Usually, bottom dwellers are good tank mates for Betta fish because Betta fish usually don’t stay at the bottom so there will be no conflict between the bottom dweller and your Betta fish.

You should avoid keeping fin nippers with your Betta fish.
