In this article, we will explore whether neon tetras can live with bettas and highlight the key considerations for keeping these fish together in the same tank.

What are Betta Fish?

Betta Fish, also known as Siamese Fighting Fish, are native to the slow-moving waters of Southeast Asia, specifically Thailand, Cambodia, and Vietnam. These fish are popular among pet owners for their vibrant colors and elaborate fins, making them a popular addition to any fish tank.

Adult Betta Fish typically grow to a size of about two and a half inches. They prefer a water temperature between 75 to 82 degrees Fahrenheit and a pH range of 6.5 to 7.5. Betta Fish require a minimum tank size of 5 gallons, with at least 2.5 inches of water per fish.

In the wild, Betta Fish are carnivorous, feeding on insects, larvae, and small aquatic creatures. In captivity, they can be fed a diet of Betta-specific flakes or pellets, supplemented with frozen or live food such as brine shrimp or mosquito larvae. Betta Fish have a lifespan of 3-5 years.

Betta Fish are known for their territorial behavior and aggressive temperament, especially towards other male Betta Fish. They also tend to show aggression towards fish with elaborate fins, mistaking them for other Betta Fish. However, they can coexist peacefully with female Betta Fish or other peaceful fish species.

Some suitable tank mates for Betta Fish include peaceful fish species such as neon tetras, cherry shrimp, African dwarf frogs, and certain types of guppies. It is important to note that tank size and water parameters should be appropriate for all fish species included in the tank to thrive.

In summary, Betta Fish are exciting and colorful fish species that require specific tank requirements and management to ensure their well-being and peaceful coexistence with other tank mates.

Can Neon Tetras Live With Betta Fish?

When setting up a community tank, it’s important to consider whether certain fish species can coexist peacefully with one another. One common question that arises is whether neon tetras can live with betta fish. While these two species can be compatible tank mates, a careful approach is necessary to ensure their coexistence.

Behavior Monitoring and Hiding Spots

Before adding neon tetras to a betta tank, it’s important to monitor the betta’s behavior. Betta fish are known for their territorial aggression and can become aggressive towards other fish, including neon tetras. Therefore, it’s crucial to provide adequate hiding spots for both the betta fish and the neon tetras. This can help reduce stress and minimize the risk of aggression.

Signs of Aggression

It’s also important to watch for signs of aggression between the betta and the neon tetras. Some signs of aggression to watch out for include chasing, nipping, and fin damage. If aggression is observed, it’s important to have a backup plan in place.

Backup Plan and Tank Divider

If aggression persists, it may be necessary to separate the neon tetras and betta fish into separate tanks or use a tank divider to provide each species with their own territory. This can help reduce the risk of aggression and ensure the health and well-being of both species.


Compatibility is an essential factor to consider in creating and maintaining a harmonious community tank. The peace and health of the tank dwellers will depend on the compatibility of the different fish species that coexist in the same tank. Factors such as behavior, tank requirements, and territorial tendencies must be carefully evaluated before bringing in any new tank mates. This article will explore the compatibility of neon tetras and betta fish, two species that are often considered as potential tank mates.

Territory and Aggression in Neon Tetras and Betta Fish:

Betta fish are known for their territorial behavior and are often kept in their own individual tanks. However, with caution, bettas can thrive in a community tank with other peaceful fish species. One popular option for tank mates are neon tetras due to their active and peaceful nature.

It’s important to note that neon tetras can often be confused with female bettas due to their similar color and activity level. However, neon tetras are much smaller in size and can be easily differentiated once observed closely.

To ensure the success of keeping neon tetras and bettas in the same tank, it’s important to look out for signs of aggression. This includes chasing, nipping, and flaring of fins. If this behavior continues, it may be necessary to have a backup plan, such as a tank divider to separate the two species.

To minimize territorial aggression between neon tetras and bettas, it’s important to provide enough swimming space and hiding spots for both species. Neon tetras do best when kept in a school of at least 6 to 8 fish, which also helps to reduce their stress levels. Additionally, bettas should have ample space to swim around and have hiding spots to retreat to if necessary.

Maintaining proper water parameters is also crucial for the overall health and success of both species. Neon tetras and bettas require similar tropical fish tank requirements, including a water temperature of 75 to 82 degrees Fahrenheit and a pH level between 6.0 and 7.5. It’s also recommended to feed them a variety of diets, including frozen and live foods like brine shrimp and mosquito larvae.

With proper care and attention to their tank environments, neon tetras and bettas can coexist peacefully in the same tank with enough swimming space and hiding spots for both species. Always be observant for aggressive behavior and have a backup plan in case the two species cannot coexist together.

Tank Size Requirements for Neon Tetras and Betta Fish in a Community Tank

When it comes to creating a peaceful and successful community tank, tank size is a critical consideration. Inadequate space can lead to territorial aggression, stress, and health problems for both Neon Tetras and Betta Fish. Therefore, it’s crucial to ensure that both species have enough space to swim around, hide, and establish their territories.

For Neon Tetras, a school of six to eight fish is ideal, as they are shoaling fish and feel more secure when kept in groups. Thus, the minimum tank size required for Neon Tetras is 10 gallons, with at least 20 gallons being the ideal tank size for optimal comfort. This allows them to have ample swimming space while also having room for hiding places and other tank mates.

Similarly, Betta Fish need ample space to swim, hide, and establish their territories. While Betta Fish are often seen living in small bowls, this is not an ideal environment for them. The minimum recommended tank size for Betta Fish is 10 gallons, but it’s always better to go for a larger tank to prevent stress and aggression. In a larger tank, Betta Fish can explore more, swim, build bubble nests, and establish their territories.

To create a harmonious community tank with Neon Tetras and Betta Fish, it’s recommended to have at least 20 gallons of water. In this larger tank, it’s safe to have three Neon Tetras for every one Betta Fish and to keep the ratio of three Tetras and one Betta for every 15 gallons of water. This ensures that both species have enough swimming space, room to establish their territories, and a peaceful environment.

Having a larger tank is always better when it comes to creating a community tank. Regardless of the number of Tetras and Bettas you want to keep together, it’s essential to choose a tank that is sufficient for both species to prevent territorial aggression and stress.

It’s worth noting that neon tetras are small fish and have a small stomach. Overfeeding them can lead to health issues and poor water quality. Keep an eye on their feeding habits and adjust as needed to maintain a healthy balance.

Overall, if you provide a balanced and varied diet for your neon tetras that includes both plant and animal sources, you’ll have happy and healthy fish swimming in your tank.

Betta Fish’s Diet and Feeding Habits

Betta fish are known to have a carnivorous diet, and it is essential to provide them with foods that contain high amounts of protein. Pellets and flakes are their primary source of food, and they should be of high quality to ensure that all their nutritional needs are met.

Feeding betta fish a small amount of food once or twice a day is ideal as they have a small appetite and tend to get full quickly. Overfeeding can cause constipation and other digestion-related problems, which can be detrimental to their health. Thus, feeding them smaller portions and monitoring their eating habits is crucial to maintain their overall wellness.

Although betta fish primarily thrive on pellets and flakes, varying their diet with frozen or live food can help keep them happy and healthy. Live or frozen brine shrimp and mosquito larvae are excellent sources of nutrients and can be fed to them occasionally.

It is essential to provide betta fish with a balanced diet of high-quality pellets and flakes with occasional servings of frozen or live food such as brine shrimp and mosquito larvae. Feeding them smaller portions regularly and steering clear of overfeeding will ensure their optimal health and well-being.

Merging Their Diets Together in One Tank

If you’re considering setting up a community tank and are wondering whether neon tetras can live with bettas, you may also be wondering whether they can share the same diet. Unfortunately, the answer is not a simple yes or no. Neon tetras and bettas have different dietary needs and preferences.

Bettas are strictly carnivores and prefer live foods such as brine shrimp, bloodworms, and mosquito larvae. These live foods are rich in protein, which is essential for their growth and overall wellness. On the other hand, neon tetras are omnivores and consume a mix of plant and animal products. They can survive on flakes and pellets formulated for tropical fish and thrive on a diverse diet that includes live and frozen foods.

Despite their different dietary preferences, it is possible to merge their diets together in one tank. A variety of flakes, frozen food, and pellets are available that both fish can consume. Some good choices include high-quality tropical fish flakes, brine shrimp, and bloodworms. You may also consider adding some freeze-dried or frozen daphnia, krill, or plankton to their diet.

It is important to feed the fish in small portions at frequent intervals to avoid overfeeding and ensure that both species are getting enough food. Overfeeding can lead to health problems such as constipation, swim bladder disease, and bloating. The general rule of thumb is to feed the fish only as much as they can eat within a minute or two.

It is possible to merge the diets of neon tetras and bettas in one tank. However, it is essential to pay close attention to the dietary needs of each fish and feed them accordingly. Offering both live and frozen foods, as well as high-quality flakes and pellets, is an excellent way to provide a diverse and nutritionally balanced diet to your fish.

Tank Setup for Neon Tetra and Betta Fish Successfully Living Together

Setting up a tank for neon tetras and bettas requires careful consideration and preparation. Both species have different requirements and temperaments that must be taken into account to ensure they can live together peacefully. Below are some important factors to consider when setting up a successful tank environment for neon tetras and bettas.

Setting up the Entire Tank for Both Fish Species

When it comes to owning multiple fish species, it’s important to consider their compatibility with each other. Betta fish, for instance, are known for their territorial behavior and can often be aggressive towards other fish. However, with the right tank setup and environment, they can coexist peacefully with other species, such as Neon Tetras.

Firstly, it’s important to choose the right tank size for these two species to live together. The minimum recommended tank size is 10 gallons, though a larger tank is always better. With a larger tank, you can create more hiding spots and provide plenty of swimming space for your fish to thrive.

Next, you’ll need to consider the hiding spots for both species to prevent stress and territorial aggression. Adding rocks, plants, and other decorations will create hiding spots for your fish, allowing them to have personal space. It’s essential to ensure your tank has enough hiding spaces because this will reduce the chances of the betta fish being aggressive towards the Neon Tetras.

Neon Tetras make a great tank mate for Betta fish because of their peaceful nature; they tend to school together and provide a school of company for each other. They’re also very active swimmers that brighten up the tank. Adding a school of Neon Tetras can make your betta fish feel calmer as well, due to their small size they become invisible to the Betta fish.

Water quality is very important to both species. The good news is that both species have similar water parameters. A gentle flow filter will help keep the water clean and provide adequate water circulation. Also, ensure maintaining the right water temperature is essential for the lifespan of your fish.

It’s recommended to introduce both species into the tank at the same time; this helps to avoid any immediate territorial disputes. Once they are in the tank, keep a close eye on their behavior, in case any signs of aggression show up. If the Betta fish shows signs of aggression despite providing enough hiding space, it’s better to separate them from Neon Tetras using a tank divider.

Lastly, always have a backup plan to separate the species if the need arises. This can be done by preparing another tank, if you have one available.

By ensuring the right tank size, hiding spots, water quality, and proper introduction methods, you can create a tank environment where Neon Tetras can coexist peacefully with Betta fish.


While neon tetras and betta fish can coexist peacefully in a community tank, it’s important to monitor their behavior and provide adequate hiding spots. Signs of aggression should be addressed promptly, and a backup plan should be in place if necessary. By taking these precautions, it’s possible to create a healthy and harmonious community tank that includes neon tetras and betta fish.
