Betta Fish Tank Mates Overview

Here are a few things you should know about your betta fish.

To keep your Betta happy, you’ll need to make sure he has enough space that he can call his territory.
Betta Fish can have very different personalities, some are more aggressive than others and may tend to harass one another, and others may not.

The Betta is a fish with lots of vibrant colors, so when selecting tank mates to keep with male or female bettas in a community, you’ll want to provide Fish that are not aggressive and don’t have long fins or colors that may intimidate the males.

Animals such as snails, shrimp, or frogs can be kept with Betta Fish, and they aren’t going to require any special conditions as they have similar habitat requirements as Bettas.

Here are a few of my favorites to start with.

Compatible Tank Mates for Betta Fish

Betta Tank Mates Depending On Tank Size

It’s not only the Fish and the temperament that makes a great tank mate, but you also need to consider the size of the tank you will be placing your Fish into.

For example;

A fish that will grow to be 2-3″ would not likely be the best tank mate for a male Betta in a 2 Gallon aquarium.

To help with your search, here is a quick list of some of the most popular and peaceful fish species, grouped by the tank size that can be added to your aquarium that your Betta will love.

Let’s dive in.

Small & Safe Betta Companion Ideas For 2.5 Gallons

Below you’ll find a few tank mates that would be perfect for 2.5 gallons.

1. Zebra Snails

  • Care Level: Easy
  • Size: 1 Inch
  • Temperature Requirements: 73-75 °F
  • PH Range: 7.5

Zebra (Nerite) Snails would live with bettas nicely and are very popular in freshwater aquariums mainly because it’s challenging to breed them in a freshwater tank, so they are doubtful to multiply like other snail species.

These snails also help remove/eat debris and algae from your tank, which helps keep things clean.

They can grow up to 1″, and you can identify them by their vivid black and gold stripes. They are super easy to care for, very peaceful, and help keep things clean, making them an ideal friend for your male Betta.

Compatible Tank Mate Ideas For a 3 Gallon Tank

Next, we’ve featured two awesome tank mates for 3 gallons.

1. Marimo Moss Balls

  • Care Level: Easy
  • Size: Varies
  • Temperature Requirements: 72-78 °F
  • PH Range: Wide Range

Marimo Moss balls are one of the best things you can put in your Betta’s tank. They are hardy and help keep the water clean and free from toxins.

2. Cherry Shrimp

  • Care Level: Easy
  • Size: 1 Inch
  • Temperature Requirements: 80 °F
  • PH Range: 6.8

These tiny red shrimp are another partner for a male Betta because they are very discreet and excellent at hiding.

One thing to keep in mind is they breed quickly so that they can overtake your tank quickly. However, they are relatively hardy and would work well in a Betta tank.

Excellent Fish For Bettas In A 5 Gallon

Next, we’ve got two options for a 5-gallon aquarium.

1. Mystery Snails

  • Care Level: Easy
  • Size: 2 Inches
  • Temperature Requirements: 68-82 °F
  • PH Range: 7.0-7.5

Another unobtrusive snail species that stay out of your Betta’s way has a hard shell for protection and can quickly retreat inside if your Betta fish starts to get aggressive. And snails are scavengers and algae-eaters, so they will do a lot to keep your aquarium clean and healthy.

Nerite snails, in particular, are excellent Betta fish companions. They are some of the best algae-eaters around; they stay relatively small at about an inch in length and don’t excessively reproduce like some other freshwater snails.

2. Feeder Guppies

  • Care Level: Easy
  • Size: 2.5″
  • Temperature Requirements: 65-80 °F
  • PH Range: 6.5-8.5

Feeder Guppies can live with bettas because they lack the bright hues of Fancy Guppies, and their small fins and muted colors won’t attract the attention of your aggressive Betta. They are also tiny, peaceful, and won’t harm your Betta by nipping at his fins.

Feeder Guppies are usually bred as food for larger Fish, but their overall blandness makes them great tank mates for Betta fish.

They are also very hardy and can survive in various tank conditions, so you won’t have to worry about balancing your tank to accommodate them.

Fantastic Companions To Live In A 10 Gallon Tank

What Fish can live with bettas in a 10-gallon tank?

The following list is a bit bigger since a 10-gallon tank gives you more room to work with. That said, be careful to go overboard when stocking your tank.

1. White Cloud Minnow

  • Care Level: Easy
  • Size: 1-2 Inches
  • Temperature Requirements: 60-72 °F
  • PH Range: 6.0-7.0

Native to Chinese mountain streams, the White Cloud Mountain Minnow is an ideal fish compatible with Bettas. This is a peaceful and easy-to-care-for fish that won’t nip at the fins of your Betta fish and won’t be seen as a threat.

They also enjoy a similar diet and water pH as Bettas, so you won’t have to find that perfect chemical balance for all your Fish to thrive.

White Cloud Mountain Minnows are used to colder water temperatures than Bettas live in, but setting your temperature around 75 degrees (F) should keep both species happy.

2. Neon Tetras

  • Care Level: Easy
  • Size: 1.5″
  • Temperature Requirements: 68-77 °F
  • PH Range: 6.0-7.5

These tetras are small freshwater Fish that get along well with Bettas; they will also add color and activity to your Betta tank and are great for beginners.

Because neon tetras stay relatively small and have a peaceful temperament, they are often found in small community aquariums and can live up to 10 years if kept healthy.

3. Ember Tetra

  • Care Level: Easy
  • Size: 1 Inch
  • Temperature Requirements: 75-82 °F
  • PH Range: 5.5-7.0

Like the other Fish on this list, the Ember Tetra is generally peaceful and submissive and is not known to nip at fins. However, unlike bright Neon Tetras, Ember Tetras have a dull color that won’t attract a Betta’s attention.

These qualities make this Fish another great buddy for your Betta fish because they won’t annoy or threaten your Betta. And if your Betta fish did try to start something, Ember Tetras are small and fast enough to escape unharmed.

Ember Tetras thrive in the same tank conditions as Bettas and enjoy tanks with a lot of vegetation to explore. A small school of Ember Tetras should peacefully coexist with your Betta Fish and will add variety to your tank.

4. Harlequin Rasbora

  • Care Level: Easy
  • Size: 1.5″
  • Temperature Requirements: 73-82 °F
  • PH Range: 6.0-7.0

Harlequin rasboras may be the ultimate Betta fish tankmate because they naturally coexist with Bettas in the wild without a problem.

Rasboras are small and not known to be aggressive or nip at fins, so the chances are low that your Bettas will see them as threatening. They are also used to the same diet and habitat as Bettas, making setting up and balancing your tank much simpler.

With their metallic orange coloring and signature triangular black markings, rasboras can add a touch of flash to your tank. So throw your Betta into a tank with a school of 8-10 Rasboras, and you should have a peaceful community of beautiful Fish.

5. Celestial Pearl Danio [Galaxy Rasbora]

  • Care Level: Easy
  • Size: 2 Inches
  • Temperature Requirements: 67-72 °F
  • PH Range: 6.0-7.5

The Celestial Pearl Danio is a relatively easy-to-care-for fish. It is best in a peaceful or well-planted aquarium of at least 10 gallons. And because of its small size and calm temperament is an excellent Betta-friendly fish.

6. Silver Tip Tetra

  • Care Level: Easy
  • Size: 2 Inches
  • Temperature Requirements: 64-82 °F
  • PH Range: 5.8-8.5

The Silver Tip Tetra is a quick, sleek tetra with shimmering white/silver fin tips. It will do best in groups of 6 in a community tank of small peaceful Fish.

7. Pygmy Cory

  • Care Level: Easy
  • Size: 1 Inch
  • Temperature Requirements: 72-79 °F
  • PH Range: 6.4-7.4

The Pygmy Corydoras is the smallest species of Corydoras Catfish, only growing to about 1 inch in length.

Corydoras are bottom feeders, so they generally won’t interfere with your Betta Fish, which prefers to cruise around the upper layers of the tank. They are also peaceful by nature, and their dull gray colors blend well with sand and gravel, so your Betta may not even notice that it has a tankmate.

Another advantage of Corydoras is that they enjoy similar conditions as Betta Fish and will do well in the same tank environment. Corydoras are the kind of Fish that gets along without issue.

A school of 6-10 small catfish in a 10-gallon tank are the perfect companions for your Betta fish, and these two species should get along swimmingly.

Here are a few more Corydoras species you can use;

8. Albino Cory

  • Care Level: Easy
  • Size: 1.5″
  • Temperature Requirements: 74-80 °F
  • PH Range: 7.0-8.0

9. Cory Catfish (General)

  • Care Level: Easy
  • Size: 1.5″
  • Temperature Requirements: 72-80 °F
  • PH Range: 7.0-8.0

10. Panda Cory

  • Care Level: Easy
  • Size: 1.5 Inches
  • Temperature Requirements: 72-80 °F
  • PH Range: 7.0-8.0

11. Ghost Shrimp

  • Care Level: Easy
  • Size: 1.5 Inches
  • Temperature Requirements: 72-80 °F
  • PH Range: 7.0-8.0

Ghost shrimp are almost translucent and are very pale, which means they are unlikely to attract the attention of your Betta fish.

They’re small and will stay out of the way, and your Betta will most likely leave them alone. They’re also scavengers, so they’ll work to keep your tank clean.

Ghost Shrimp prefer aquariums of at least 10 gallons with plenty of hiding places. With a small community of Ghost Shrimp alongside your Betta, you should have a clean and peaceful tank.

12. Nerite Snail

  • Care Level: Easy
  • Size: 0.5-1 Inches
  • Temperature Requirements: 72-80 °F
  • PH Range: 7.5-8.0

13. African Dwarf Frog

African Dwarf Frogs are excellent companions for Betta Fish because there’s no way your Fish will mistake them for another Betta, so it will have little reason to attack.

These frogs will also stay near the surface of your tank and will be out of your Betta’s way most of the time. They are also able to survive in similar conditions.

Even though you’re Betta won’t be provoked by the appearance of the African Dwarf Frog, you should still look to ensure your Fish isn’t nipping at your frogs from below.

Medium-Sized Betta Fish Tank Mate Ideas For A 15 Gallon Tank

For a 15-gallon tank, you can continue using all of the recommendations above, plus the following two options that will need a bit more room.

1. Clown Pleco

  • Care Level: Easy

A type of armored catfish is a docile algae-eaters and can be an excellent companion.

These Plecos are strikingly beautiful with luminescent yellow and dark black stripes, so they will surely add to the aesthetics of your tank.

They are smaller than other Plecos but can still grow to about 4 inches in length and will need a tank of at least 29 gallons.

2. Fire Rasbora

  • Care Level: Easy
  • Size: 2 Inches
  • Temperature Requirements: 76-84 °F
  • PH Range: 6.0-7.0

We’ve got you covered in the following two sections.

Read on.

Female Betta Fish Tank Mates – Sorority Tanks

Since the female Betta Fish is typically much less aggressive than the betta fish, you can sometimes be slightly more relaxed in your choice of neighbors.

With that in mind, any of the Fish above will do, but you can also keep other female bettas in the tank to create a sorority tank.

What is a Betta Sorority tank?

It’s a group of female bettas in one community aquarium. The bigger the aquarium, the better, so look at 15 gallons or larger, so if any of the females become aggressive, there is more than enough room to swim and hide.

So, what Fish can live with female bettas?

Here are some great options for female tank mates;

  • Neon Tetra
  • Black Neon Tetra
  • Silver Tip Tetra
  • Diamond Tetra
  • Glowlight Tetra
  • Silver Tip Tetra
  • Ember Tetra

What Fish Can Live With Male Bettas?

Unlike the female Betta, males can’t be kept in the same aquarium as other males (with some exceptions).

With that in mind, any of the Fish above will do. Just be careful not to crowd your Betta fish and have the right sized tank for the Fish you want to keep.

So, what Fish can live with female bettas

Below are my favorite tank mates for a betta;

  • Nerite Snails
  • Otocinclus
  • Most small Tetras & Rasboras

Can Male And Female Betta Fish Live Together?

Yes, male and female Bettas can live together in one tank. However, be prepared for lots of babies. Also, be sure to provide lots of hiding places for the female Bettas as the male can get aggressive sometimes, especially during breeding.

What Makes a Good Tank Mate for Your Betta Fish?

Before we get into the list of good playmates, here are a few things to consider when deciding if a fish will make an excellent addition to your Betta community tank.

  • Ensure you have the proper Betta fish set up and that your tank is big enough. If your Betta’s tank is less than 10 gallons, you shouldn’t try to add other Fish. As far as tank size goes, bigger is better.
  • Make sure there is plenty of vegetation and natural features. Bettas and other Fish need to hide and take shelter.
  • It may be easier to add your Betta to an already-established community tank than to add other Fish to your Betta’s territory.
  • Avoid putting two Bettas in the same tank.
  • Avoid Fish with long, flowy fins or bright colors that Betta might mistake for another male.
  • Avoid Fish that are known as “nibblers.” They will nibble at your Betta’s fins, injuring it and potentially causing it to become aggressive.

Introducing New Tank Mates To Your Betta [Video]

Check out this excellent video for a tutorial on introducing new tank mates into your Betta tank:

How to Introduce Tank Mates to a Betta Aquarium

What Fish Are Compatible With Male Betta Fish?

Bettas can coexist with other Fish in a community tank despite their reputation.

A few examples of tank mates living peacefully with Betta are White Cloud Minnows, Neon Tetras, Ember Tetra, and Harlequin Rasbora. Of course, most freshwater shrimp and snails can also live with your Betta.

Because of these potential issues, many people will keep Betta in a separate tank. But if you want a colorful and happy Betta, make sure you do some research and be careful when adding a Betta to a community tank.

Can Betta Fish Live With Other Fish?

Betta Fish can live with other Fish than what you’ll find on this list.

However, Betta is also known as the Siamese Fighting Fish for a good reason. They have an aggressive side and can be very territorial, and a betta would try to nip the fins of other Fish or, worse, fight, which can often lead to injury or death.

Do Betta Fish Need Tank Mates To Be Happy?

Bettas do not need companions and do very well independently, provided they have a large enough tank and the proper requirements.

It is important to keep in mind that they in no way require any friends in the aquarium! HomeAquaria.com

However, if your tank is large enough, you can add a few companions that will undoubtedly add some fun for your little buddy.

If you believe your little friend is unhappy because he isn’t moving around as much, keep in mind there are many reasons Why Your Betta Fish Is Not Moving.

Can Betta Fish Live With Mates and Stay Peaceful?

Yes, Betta can be kept with all kinds of community fish.

That said, it is essential to do your research and understand how big the Fish will get, their temperament, and their water parameters.

Keep in mind:

Tank size is also critical, and as you’ll see below, you’ll need to make sure to have a large enough tank size depending on which companions you want to keep with your Betta.

Final Thoughts On List Of Fish That Can Live With Bettas

Any of the above species have the potential to make excellent Betta friends. Even so, when establishing your community tank, monitor your Betta’s reaction to the other Fish and keep an eye out for any aggressiveness.

If done correctly and carefully, you should be able to create a thriving community tank around your beautiful Betta.

The success of creating a community tank with Bettas ultimately depends on the temperament and personality of your individual Betta.

But the species listed here can make excellent buddies for your Betta Fishes and will give you the highest chance of having a peaceful and happy aquarium.
