Are you planning to add some companions to your betta fish in your aquarium? You have to select the right fish species that can coexist with your betta peacefully. While bettas are known for their colorful and flamboyant fins, they are also infamous for their aggressive nature and may attack some fish species.

1. Neon Tetras

Neon Tetras are one of the most compatible fish species to share an aquarium with betta fish. These small, vibrant fish are peaceful and won’t pose any threat to your bettas. Neon tetras require similar water parameters to bettas, which makes maintenance easier for hobbyists. The recommended space for these fish is a minimum of 10 gallons, with 5-6 tetras being a good fit to ensure they feel secure in the community.

It is crucial to avoid any fish that may nip at betta’s fins. But fortunately, neon tetras are known to be peaceful and non-aggressive fish species. The only problem you may encounter with neon tetras is that they can become fin nippers if they are kept in large numbers in a small tank, which can be resolved by providing them with a larger tank. Other than that, they are perfect tank mates for betta fish and provide an impressive display with their neon blue color.

2. Cory Catfish

They prefer schooling so keeping at least three in a group is advisable for their well-being. They can thrive in the same water conditions as bettas, but they require a soft substrate, so make sure to have sand or fine gravel rather than rough gravel in their tank.

Their small size allows them to move freely within the aquarium and not bother the betta. They are best suited for a 10-gallon aquarium or larger for groups or multiple species.

3. Kuhli Loaches

The Behavior of a Betta fish

Betta fish behavior

Betta fish are a popular choice among fish keepers because they display a variety of interesting behaviors. Bettas are known for their aggressive behavior towards other fish, including other bettas. This is because betta fish are territorial and fiercely defend their space against intruders. Understanding the characteristics of a betta fish can help you select the right companion fish that will peacefully coexist with your betta fish.

Betta fish are active and alert. They are known to be interactive with their owners and enjoy playing and exploring their surroundings. These fish are intelligent and can recognize their owners, which allows for them to be trained to do tricks and respond to commands. Betta fish are also known to build bubble nests as a sign of courtship and breeding.

When it comes to living with other fish, it’s important to note that not all fish are compatible with bettas. Some species are known to be aggressive or fast swimmers, which can intimidate or stress out the betta. Other fish may not be able to withstand the water temperature or water parameters that bettas require.

When choosing a companion fish for your betta, it’s best to choose a fish that is peaceful, slow-moving, and fits the size requirements. Fish such as neon tetras, cory catfish, and shrimp are often suitable companions for bettas. These species are schooling fish, which can help reduce stress levels for the betta, as they do not feel alone in their environment.

It’s important to keep in mind that the addition of any fish to a betta’s tank can cause stress or aggression in the betta. When introducing new fish, it’s recommended to do so slowly and in a controlled environment. Pay attention to the betta’s behavior and adjust accordingly.

If you choose to add other fish to your betta’s tank, make sure to provide plenty of hiding places and plants to break up the line of sight. This will allow both the betta and companion fish to have their own space and reduce the chances of them fighting or stressing each other out.

In conclusion, understanding the behavior of a betta fish can help you select the right companion fish for your tank. It’s important to choose a peaceful species that fits the size requirements and can coexist with the territorial nature of a betta fish. By carefully selecting the tankmates for your betta, you can create a harmonious and visually appealing environment for all your fish to thrive in.

Cory catfish make excellent tank mates for betta fish due to their peaceful nature and similar dietary requirements. They are bottom-dwelling scavengers that help keep the aquarium clean by eating leftover food and debris. They also come in a variety of colors and patterns, adding visual interest to the tank. When adding cory catfish to a betta fish tank, it’s important to have a minimum of four to six fish to prevent them from feeling stressed or intimidated.

2. Neon Tetras

Neon Tetras

Neon tetras are popular aquarium fish with a peaceful temperament, making them a great fit for betta fish tanks. Their bright blue and red coloring is visually striking and can add a pop of color to your aquarium. It’s important to keep a school of at least six neon tetras in the tank, as they are a schooling fish and feel more comfortable in groups. It’s also recommended to avoid adding long-finned tetra species to the betta tank as the betta may attack them due to their long and flowing fins.

Fish To Avoid If You Own a Betta Fish

If you have a betta fish, it is important to choose its tank mates carefully to avoid any conflicts and ensure a peaceful aquarium environment. Betta fish are known to be territorial and aggressive towards other fish, so finding the right companion can be a challenge. Here are the types of fish you should avoid if you own a betta fish.

1. Other Betta Fish

Betta Fish

It may seem like a good idea to introduce another betta fish to your aquarium. However, this is a bad idea as bettas are very territorial and will become aggressive towards another betta to protect their own territory. Keeping two betta fish in the same tank will result in a fight to the death between them.

2. Guppies


Guppies are known for their bright colors and peaceful nature, but they should not be paired with bettas. Betta fish are known to see guppies as food, and they may attack them if they get the chance. Additionally, guppies may nip at the fins of bettas, causing stress and possibly leading to fin rot.

3. Neon Tetras

Neon Tetras

While neon tetras are peaceful fish that can live in harmony with many other species, they should not be paired with bettas. Neon tetras are small and can easily become prey for your betta fish. In addition, the neon tetras’ bright colors and fast movements may provoke the betta into aggressive behavior, resulting in injury or death for the neon tetras.

4. Goldfish


Goldfish are big and bulky, and betta fish may see them as a threat or competition for space. Additionally, goldfish prefer colder water temperatures, while bettas thrive in warmer waters. Goldfish produce a lot of waste, which may negatively affect the water quality in your aquarium and impact the well-being of your betta. It is best to keep goldfish in their own tank without any other fish companions.

In conclusion, it is important to choose the right tank mates for your betta fish to ensure a peaceful and happy aquarium environment. Keep in mind that bettas are territorial and aggressive towards other fish, so it is best to avoid pairing them with other bettas, guppies, neon tetras, and goldfish. Stick to peaceful, non-threatening fish that have similar water temperature and pH requirements for the best chance of success.

Choosing the Right Fish for Betta Tank Mates

Choosing the Right Fish for Betta Tank Mates

When it comes to choosing fish that can live peacefully with bettas, you need to carefully consider the species’ temperament, size, and dietary needs. Here are some popular tank mates for bettas:

  • Schooling Fish: Neon tetras, cardinal tetras, harlequin rasboras, and ember tetras are all small, active, and peaceful schooling fish that can live with bettas. Just make sure to keep them in groups of six or more to prevent bullying.
  • Corydoras Catfish: These catfish are bottom-dwellers and can help keep the aquarium clean by eating leftover bits of food. Corydoras catfish are also peaceful and won’t bother your betta.
  • Mystery Snails: Snails are a great addition to any tank because they feed on algae and help keep the aquarium clean. They are slow-moving and won’t threaten your betta.
  • Bristlenose Plecos: These small catfish are great algae eaters and won’t bother your betta. Just make sure you have a large enough tank for them to grow and thrive.
  • Guppies: Guppies are small, colorful fish that can add a pop of color to your tank. They are also active swimmers and won’t cause any trouble for your betta.

It’s important to note that not all fish will be compatible with bettas. Avoid adding any fish that are known to be aggressive, fin-nippers, or ones that require vastly different water parameters than bettas.

Additionally, keep in mind that bettas are territorial fish and don’t like it when other male bettas are in the same tank. If you want to have more than one betta, you’ll need to keep them in separate tanks.


Betta fish and companion fish

Choosing the right companion fish for your betta fish plays a significant role in creating a harmonious and peaceful environment in your aquarium. It not only helps to reduce stress in betta fish but also enhances the aesthetic appeal of your tank.

When selecting a companion fish for your betta, it is crucial to know their compatibility. Some fish species tend to be aggressive or territorial, and they may pose a risk to your betta fish. Thus, it is essential to choose a fish that is calm and does not mind sharing the tank with another fish.

Moreover, it is vital to ensure that the companion fish and betta fish’s living requirements are the same. This includes factors such as water pH, temperature, and quality. Some species have specific needs, and failing to meet their requirements can lead to stress, illness, and even death.

As a result, it is crucial to familiarize yourself with the fish species you intend to keep in the same tank with your betta. This includes their dietary needs, water conditions, and temperament to ensure harmony and compatibility.

One crucial aspect of creating a peaceful environment for your fish to coexist is providing enough space. Overcrowding the tank can lead to fights, stress and may reduce the quality of the water in the tank. The general rule of thumb for a betta fish is providing at least five gallons of water per fish.

Another tip for ensuring successful coexisting is adding tank decorations and plants to create territories. Betta fish require territorial spaces, and creating this in a shared tank environment can reduce fights between the fish species. Plants and decorations can create a division line, providing each species with an area to call its own.

In conclusion, selecting the right companion fish for your betta and understanding their requirements is the key to creating a harmonious and peaceful environment. It requires researching and understanding the species you intend to keep in your tank, providing sufficient space, and adding decorations and plants for creation territories. Following these tips can help you successfully coexist your betta fish with other species in your aquarium.
