Can Betta Fish Live With Tetras?

In this blog post, we will answer the question of whether or not betta fish can live with tetras. There are a lot of factors to consider when deciding which type of fish can live together in an aquarium.

It’s important to make sure that the tank is big enough for all the fish and that they have similar needs. We’ll discuss these considerations below and then give you our opinion on whether or not bettas and tetras should be living together in one tank!

Can Betta Fish Live With Tetras?

Yes, bettas and tetras can live together in the same tank. However, it’s important to make sure that the tank is big enough for both fish and that their individual needs are met.

Getting it wrong can result in your betta and tetra fighting each other for territory and food. There are many other factors that will influencer your decision, like the gender and size of your fish, which will we go into.

The Gender Of Your Betta & Tetra

When it comes to the gender of your betta and tetra, it’s important to remember that males are more territorial than females. Male betta fish frequently fight other male bettas, but they can be kept with other fish as long as the tank is big enough.

Female bettas, on the other hand, are more peaceful and can be kept with other fish of either gender in a bigger tank. Also, female bettas have smaller fins, so they are less likely to be nipped by aggressive tetras.

When it comes to tetras, both male and female tetras can live together peacefully. However, it’s important to remember that male tetras are known to nip other fish’s fins. If you have male tetra in the same tank, make sure to watch them closely to see if this becomes an issue.

How Many Bettas Can I Keep With My Tetras?

Tetras like to live in schools, so it’s important to have at least six tetras in your tank if you want them to be happy. As such, I recommend one or two bettas for every six tetras in your tank, although be careful with keeping two male bettas together.

Tank size matters too! If your tank is too small, the bettas and tetras will become stressed and may start to fight. Make sure to give your fish plenty of space!

Will Betta Fish Eat Baby Tetras?

Yes, if the tetras are very small and the bettas are hungry, then it’s possible that they will eat small tetras. If you want to keep your tank safe and avoid this from happening, make sure the tetras are full size and that the bettas are well fed.

My Tetras Are Eating My Bettas Food

One of the problems with keeping bettas and tetras together is that the tetras may start to eat the betta’s food. This can be a problem if your betta is on a special diet. To avoid this, try feeding your bettas at different times than your tetras. This will help to make sure that the bettas get enough food, while also keeping the tetras away from their food.

It is important to make sure that your fish stay well-fed and don’t fight for food with each other. You can do this by having multiple feedings per day or using different feeding times for your fish.

Another thing you could try is adding a plant to the tank that the tetras can nibble on. This will help to keep them occupied and away from the betta’s food. They might not even notice that you have given food to your betta if they are distracted by a moss ball or other tank toy.

How Do I Introduce My Betta to Tetras?

If you’re thinking about adding tetras to your tank, it’s important to do a slow introduction. This will help to make sure that the betta doesn’t become stressed and start fighting with the tetras.

I recommend first putting the new fish into a quarantine tank for a few days before adding them to your main tank. This will help you avoid introducing any diseases and it gives the fish time to adjust slowly before entering a new environment with other fish in it.

Start by adding one or two tetras to the tank and then wait a few days before adding more. Watch how the betta and tetras interact with each other to make sure that they aren’t fighting or chasing each other around. You should also keep an eye on the bettas color, as this can change when it becomes stressed out.

If everything goes well, then after a few days it should be safe to add all of the tetras that you want into your tank! Just remember not to overcrowd them or keep multiple bettas together in the same tank.

Caring for Bettas and Tetras at the Same Time

Luckily tetras and bettas have similar care needs. They can both do well in water temperatures ranging from 76-82 degrees Fahrenheit and they like the same kinds of pH levels (around 7).

You should also make sure the water is well oxygenated and that there is plenty of vegetation for the fish to hide in. If you do this, then your betta and tetras should be able to thrive together!

Both fish prefer dim lighting, so make sure to keep your tank lights turned down. This will help to create a more natural environment for the fish and it will also help to reduce stress levels.

Can Tetras Eat Betta Food?

Tetras are omnivorous fish, which means that they can eat a combination of plant and meat food. Bettas are carnivorous fish that only need to eat protein-rich foods in order for them to stay healthy.

Tetras will do fine on a diet of fish flakes, whereas bettas need to have a diet with lots of protein-rich pellets and some live food. This means that the tetras and bettas will need to be fed separately in order for them both to stay healthy!

It’s fine for both fish to share live foods, like bloodworms. They shouldn’t be given every day, but they are a good source of protein for both fish.

What Tetras Shouldn’t Live With Bettas?

While most tetras will live peacefully with bettas, there are some tetras that you may want to be cautious of.

Black Phantom Tetras and Bettas

This type of tetra LOVES to play fight, which means they will constantly try to play fight with your betta if you put them together. This can stress out your fish and might even lead to the death of a tetra or a betta!

Black tetras are also slightly nippier than other tetras, so they may nip at your betta’s fins. If you have a black tetra in your tank, make sure to keep an eye on them and remove them if it becomes a problem.

Bleeding Heart Tetras and Bettas

Bleeding heart tetras are nippy and fast fish that may start to nip at your betta’s fins. This means your betta may feel overwhelmed and stressed out by all of the nippings.

If you want to keep bleeding heart tetras, make sure that they are in a large tank with lots of hiding places and try not to overcrowd them. You should also check on your betta often to see if it’s getting nipped at too much!

Serpae Tetras and Bettas

This type of tetra tends to go after fish that are colorful and bright… like betta fish. They are also fast swimmers and nippers, so they will most likely be the ones starting any fights.

What Tank Do I Keep Tetras and Bettas In?

You will need a large tank that is at least 20 gallons if you want to keep tetras and bettas together. This will give them plenty of space to swim around and avoid any fights.

If you have a large tank, you can also add other fish that would usually be housed with tetras, like guppies or platys. Just make sure that the fish are compatible with each other and won’t fight.

If you want to add plants into your aquarium, then make sure they are live plants instead of plastic or silk plants. Betta fish like to play and hide in the plants so they may be less likely to start a fight if their tank has lots of hiding spots.

You can also add toys to the tank, like caves, which your fish may appreciate! Just make sure that the toys are sturdy and won’t fall apart if your betta decides to play with them.

What Else Should I Consider?

When thinking about keeping bettas with tetras, it’s important to remember that these fish come from very different environments. Bettas and their tank mates need a lot of space and high water quality in order to be healthy – especially if they are sharing the same tank!

Tetras typically live in warm waters where there is not much plant life. Your betta, on the other hand, will definitely not be happy in a tank with no live plants!

If you have multiple tanks or are thinking about upgrading your current one, I would recommend considering adding some live plants to it before bringing any fish into it. This is because they can both provide hiding places for animals and help to keep the water clean.


In conclusion, you can add tetras to your betta’s tank as long as you do a slow introduction and consider their different needs. Make sure to keep an eye out for any signs of stress or fighting between the two types of fish, and remove either one if necessary!

I hope this helps you decide if adding tetras to your tank is the right decision for you and your betta.
