Best Tank Mates For Bettas In A 10 Gallon Tank

Here are some of the best choices for your Betta’s tank and their care requirements, so you can give them all the love they deserve! 

Mystery Snails (Pomacea Bridgesii)

Mystery Snails are some of the coolest snails you can have in your tank with bettas. They come in a wide variety of colors and patterns, and each one has its own unique personality and appearance. Trust me, once you have these little guys in your tank, you won’t be able to take your eyes off them!

If you plan on adding Mystery Snails to your aquarium, remember that they can breed quickly and take over your tank. Keep an eye on their population and take measures to control their numbers. If you have a planted tank, be cautious as these snails can eat your plants. Ensure you choose plants that can withstand them.

Mystery Snails are pretty easy to take care of, and they can add a lot of personality to your aquarium. They can grow up to 2.5 inches and have a lifespan of 1-2 years. To keep them healthy and happy, maintain a pH level between 7.0-8.0 and a temperature between 68-82°F. 

Ghost Shrimp (Palaemonetes Paludosus)

Ghost Shrimp Care Sheet

Adding tank mates for your betta can be a bit tricky, but Ghost Shrimp are a great option to start with. Not only are they affordable, but they’re also known to be peaceful towards other fish. This makes them an ideal choice for a community tank, especially if you’re unsure about how your betta’s going to behave around other fish.

Ghost Shrimp are named so because of their translucent appearance, which gives them a unique and interesting look. They look like glass catfish, making them a visually appealing addition to any tank. They’re also great algae eaters, which means that they can help keep the tank clean!

These shrimp can grow up to 1.5 inches in length and have a lifespan of about a year. They thrive in a pH range of 7.0-8.0 and a temperature range of 65-80°F. 

Dwarf Crayfish (Cambarellus Patzcuarensis)

Dwarf Crayfish Care Sheet

Aside from their unique look and amazing personalities that will keep you entertained, Dwarf Crayfish are bottom dwellers, which means they will hardly come into contact with your betta fish, who generally prefer staying at the top of the tank. 

Adding dwarf crayfish to your betta fish tank is a great way to keep the bottom of the tank clean. They’re scavengers and will feed on any leftover food that falls to the bottom. This will reduce the amount of uneaten food and waste that accumulates in the tank. 

However, it’s important to note that dwarf crayfish are invertebrates. So, you should never add copper medication to your tank as it will harm and eventually kill them.  

Dwarf crayfish can grow up to 1.6 inches in size and have a lifespan of up to 3 years. They thrive in a pH range of 7-8 and a temperature range of 68-82°F.

Ember Tetras (Hyphessobrycon Amandae)

Ember Tetra Care Sheet

If you’re looking for a colorful and lively addition to your Betta tank, consider adding Ember Tetras. They may be smaller than most other tetras, but they make up for it with their fiery red color and lightning-fast swimming. They have streamlined bodies that allow them to dart around the tank with ease!

Ember Tetras are great tankmates for bettas because they are fast swimmers, making it unlikely for bettas to catch them. These peaceful fish also get along well with other fish, making them a great addition to a community tank.

However, it’s important to note that Ember Tetras should be kept in groups to prevent stress and unhappiness. They grow to be about 0.8 inches in size and have a lifespan of 2-3 years. To keep them healthy and happy, maintain a temperature between 73-84°F and a pH between 6-7 in their tank.

Guppies (Poecilia Reticulara)

Guppy Care Sheet

Guppies are a great option to keep with bettas, as long as you take some precautions. Guppies and bettas have different temperaments, but if you stick to female guppies, you should be able to avoid any aggressive behavior. Female guppies are less colorful than males, which can reduce the likelihood of a betta attacking them.

One of the reasons why guppies are good tankmates for bettas is because they are peaceful, active, and playful fish. They also come in a variety of colors, which can create a beautiful contrast in your tank.

It’s worth noting that guppies have some specific requirements when it comes to water conditions. They need a pH level between 6.8 – 7.8 and a temperature between 74-82°F. They also need good quality water and enough space to swim around.

When adding guppies to your tank, it’s important to have a backup plan in case anything goes wrong. You can expect your guppies to live for up to 5 years in some circumstances, however, anywhere between 1-3 is more normal. As well as that they can also grow up to 2.5″ in length for females and 1.5″ in length for males.

African Dwarf Frogs (Hymenochirus Boulenger)

African Dwarf Frog Care Sheet

If you’re not a fan of having fish, shrimp, or snails as tank mates for your betta, then you might want to consider African dwarf frogs. African dwarf frogs are bottom dwellers, so they won’t get in the way of your betta’s swimming space. They spend most of their time at the bottom of the tank, which means they won’t compete with your betta for space.

One reason why African dwarf frogs are great tank mates for bettas is because they are easy to care for. They don’t require much attention, and they can survive in a wide range of temperatures and pH levels. 

If you plan to add African dwarf frogs to your betta tank, keep in mind that your tank should not be too high and you need to be careful when feeding them as they can become aggressive during feeding time.

African dwarf frogs can live for up to 8 years and grow up to 2.5″ in length. They can thrive in temperatures between 70-80°F and a pH level between 6.5-7.5.

Amano Shrimp (Caridina Multidentata)

Amano Shrimp Care Sheet

Amano shrimp are known for their ability to help keep the tank clean by eating algae. They’re also great tank mates for bettas due to their calm nature and large size. Despite not being as colorful as other fish, their size makes them a much less likely target for bettas to attack.

Amano shrimp are peaceful and won’t cause any trouble, but they can be a bit competitive during feeding time, so you might see them stealing food from other creatures in the tank. In fact, my biggest amano shrimp would always grab a sinking pellet and scuttle to a corner of the tank away from all the other shrimp and corys.

And the best part is that they can’t breed in freshwater, so you don’t need to worry about them multiplying and taking over your aquarium.

It’s important to provide plenty of hiding spaces for the Amano shrimp because they can be quite shy. They can grow up to 2 inches and usually live for 2-3 years. They prefer a temperature range of 70-80°F and a pH between 6.5-7.5. 

Harlequin Rasboras (Trigonostigma Heteromorpha)

Harlequin Rasbora Care Sheet

With proper care, Harlequin Rasboras can be one of the best additions to your betta tank. Unlike other fish, they’re fast swimmers, which means that they won’t be easily caught by your betta. They’re also colorful, making your tank to look even more beautiful. 

One great thing about keeping Harlequin Rasboras with your betta is that they don’t require any special conditions. These little fish are native to the same habitat as bettas, so they can thrive in similar water conditions. They can also live for up to 5-8 years and grow up to 2 inches in size. 

To keep your Harlequin Rasboras healthy and happy, make sure to maintain a temperature between 72-81°F and a pH level between 6.0-7.5 (a pH level closer to 7.2 is ideal). 

Pygmy Corydoras (Corydoras Pygmaeus)

Pygmy Corydoras Care Sheet

If you’re wondering what kind of tank mates you should choose for your betta fish, Pygmy Corydoras catfish are the perfect example. Unlike bettas, they’re not brightly colored, they don’t have flowing tails, and they don’t inhabit the same areas. They’re the perfect complement for your bettas!

Pygmy Corydoras are one of the best tank mates for bettas because they’re peaceful, easy to care for, and have hard armor-like scales that protect them from any aggressive behavior from your betta. They’re also great for new betta keepers who are not sure if their betta will be aggressive.

Another great thing about Pygmy Corydoras is that they can live happily in tanks as small as 10 gallons, which makes them perfect for smaller aquariums. They normally live for up to 3 years and grow up to 1 inch in size.

To ensure that your Pygmy Corys are healthy and happy, you need to keep their water temperature between 72-79°F and maintain a pH between 6.0-8.0. Also, make sure that the nitrate levels are low to keep them healthy. 

Bronze (Common) Corydoras (Corydoras Aeneus)

Common Corydoras Care Sheet

If you want corydoras that are a little bit bigger, then bronze corydoras’ are a great choice. They’re brown, and often do best in groups of 3 or more. And don’t worry about their slightly larger size, they still live happily in a 10-gallon tank. Just make sure you keep the water pristine.

Just like other cory’s, they’re also ideal tank mates for bettas because they don’t have any of the features that trigger aggression in bettas. While bronze corydoras’ are bottom dwellers, it’s not uncommon for them to swim to the surface to breathe air either.

If you want to keep bronze corydoras catfish with your betta then you should be aware that they can live for up to 10 years and grow up to 2.5″ in length. On top of this, they’re going to need to live in a tank with a temperature between 68-82°F and a pH between 6.0-8.0.

Dwarf Rasbora (Boraras Maculatas)

Dwarf Rasbora Care Sheet

If you’re searching for some smaller fish that are compatible with your betta, consider dwarf rasboras. These tiny fish grow up to only 0.8 inches, but their speed and agility makes it almost impossible for bettas to catch them. 

Also, you’ll be glad to know that Dwarf Rasboras are really easy-going and peaceful. They won’t compete with your betta for space and are happy to swim together in schools. 

Now to create a safe and comfortable environment for them, make sure you provide lots of hiding places. Although dwarf rasboras love plants, feel free to add driftwood, caves, or other ornaments. 

And the best part about caring for Dwarf Rasboras? These hardy little fish can live up to 5 years if you keep the temperature between 68-82°F and pH level between 4.5-6.5. 

Endler’s Livebearers (Poecilia Wingei)

Endler's Livebearers Care Sheet

Endler’s livebearers are a great choice if you’re looking for some peaceful, low-maintenance fish to add to your Betta tank. They look quite similar to guppies, but unlike guppies, they’re not as flashy and don’t have any flowing fins. 

One thing you should keep in mind if you decide to add Endler’s livebearers to your tank is that they breed like crazy. These fish are some of the most prolific breeders out there, which can be both a blessing and a curse. 

On the one hand, it’s great to have a healthy population of fish in your tank. On the other hand, if you’re not careful, their breeding can get out of control pretty quickly.

But here’s the good news:  Endler’s livebearers make excellent Betta tank mates. Bettas can be quite picky eaters, but they love to snack on Endler’s livebearer babies. Not only that, but Endler’s livebearers are peaceful fish that won’t cause any trouble or compete with your betta.

Endler’s livebearers can grow up to 1.8 inches in size and live for 2-3 years. Females typically live slightly less long than males. They are happiest in water temperatures between 68-82°F and pH levels between 6.5-8.5.

Lambchop (Esme’s) Rasbora (Trigonostigma Espei)

Lambchop Rasbora Care Sheets

Last on the list of the best betta tank mates for 10-gallon tanks is Lambchop Rasboras!  These fish are easy to get along with and won’t make any trouble for your betta.

Lambchop Rasboras are super chill fish with calm personalities, which makes them perfect for sharing an aquarium with your betta. Plus, they’re not flashy or colorful, so your betta won’t feel threatened by their presence.

These little fish are also pretty hardy and can live for up to 2-3 years if you take good care of them. They prefer to live in water that’s a little bit warm, between 72-82°F, and with a pH level between 6.0-7.0. 

They can grow up to 1.5 inches long and are pretty social creatures, so they’ll make a great addition to your aquarium.

How To Increase The Chances Of Success

Bettas, while beautiful and captivating, can be territorial and sometimes aggressive. However, by following these guidelines, you can create a harmonious and thriving community tank.

  1. Right Tank Size: Make sure your tank is roomy enough for your Betta and its tankmates to live comfortably. A larger tank means fewer territorial issues.
  1. Choose Peaceful Tankmates: Pick fish known for their chill personalities. Think of small community fish like neon tetras, harlequin rasboras, or corydoras catfish.
  1. Go for Schooling Fish: Consider fish that like to hang out in groups. They’re less likely to bother your Betta because they’ve got their own gang to socialize with.
  1. Keep Sizes Balanced: Get tankmates that are about the same size as your Betta or a bit bigger. It’s a balance thing – too-small fish might seem like snacks, and that’s a no-no.
  1. Water Conditions: Make sure the water’s just right for everyone. Betta fish prefer it a bit warmer (78-82°), but ensure that your other fish can handle it too.
  1. Hideouts Are a Must: Set up hiding spots with real or fake plants, caves, and decorations. These give fish a getaway spot when they need a break or want to show off their turf.
  1. Use Visual Blocks: Arrange your decorations and plants so that fish can’t see each other all the time. This cuts down on squabbles and keeps the peace.
  1. Introduce Fish Slowly: Don’t rush the friend-making process. Add new fish little by little, so everyone has time to adjust without getting shocked.
  1. Keep an Eye Out: Pay close attention to how your fish are getting along at first. If you spot any trouble, like one fish chasing another, be ready to change things up or separate the feuding parties if needed.
  1.  Fair Feeding: Make sure every fish gets enough to eat during meals. Watch to make sure the Betta doesn’t hog all the food. You can use feeding rings or section off parts of the tank if things get competitive.
  1.  Know Your Betta: Remember, each Betta has its own personality. Some are laid-back, while others are more territorial. Be flexible and adjust your tank’s mix if needed.

How To Add Tank Mates To Your Bettas Tank

Now, here’s a step-by-step guide on how to add tank mates to your Betta’s tank:

Quarantine New Fish: Before introducing new fish to your Betta’s tank, quarantine them in a separate quarantine tank for at least two weeks. This helps prevent the spread of diseases and parasites to your main tank.

Check the Health: During quarantine, closely observe the new fish for any signs of illness or abnormal behavior. Treat any health issues if necessary.

Ensure Proper Water Parameters: Confirm that the water temperature, pH, and hardness in your Betta’s tank match the requirements of the selected tank mates. Make any necessary adjustments.

Dim the Lights: Dim the tank lights to reduce stress and aggression among the fish. This can help calm your Betta and make it more receptive to new tank mates.

Introduce the New Tank Mates: Place the new fish into the Betta’s tank first, before reintroducing the Betta itself. This allows the new fish to establish their territories before the Betta reclaims its space.

Use a Distraction Technique: While adding the new fish, you can distract the Betta by gently tapping the tank’s surface or dropping some food at the opposite end of the tank.

Monitor Behavior: Observe the behavior of all the fish in the tank closely for the first few hours 

and days after introduction. Look for signs of aggression, territorial disputes, or stress.

Be Prepared to Separate: If you notice aggressive behavior, have a tank divider or a separate quarantine tank ready to temporarily separate the Betta or the aggressor.

Maintain Peaceful Feeding: During feeding times, make sure all your fish receive enough food. Watch your Betta to ensure it doesn’t eat all the food.

Regular Monitoring: Regularly monitor your tank’s inhabitants to ensure they coexist peacefully. Look for changes in behavior, signs of illness, or distress among the fish.

Be Patient and Flexible: Fish can take time to establish their territories and hierarchies. Be patient and prepared to make adjustments if needed, such as rehoming an aggressive fish or adding more hiding spots.

Can You Keep More Than One Betta In A 10 Gallon Tank?

A 10 gallon tank can either house a single male betta or 2-3 female bettas. Alternatively, you can keep 2 males with a tank divider, but it’s better to add other tank mates to reduce the chance of aggression. Don’t keep males or females together for a long time unless you plan on breeding them.


Choosing the right tank mates for your 10-gallon Betta aquarium is fun and easy! With proper introduction, you can create an enchanting underwater ecosystem where your Betta and its companions can live happily!
