Bettas and Guppies: Can They Live Together?

Betta fish and guppies are two of the most popular freshwater fish for aquarium owners. Their unique colors and active personalities make them great additions to any tank.

However, some people may wonder, can bettas and guppies live together? The answer is not a simple yes or no.

It depends on various factors, including compatibility, differences and similarities, and tank size.

Compatibility of Bettas and Guppies

Bettas, also known as Siamese fighting fish, are notorious for their aggressive behavior. Male bettas, in particular, are territorial and may attack other males, especially those with long, flowing fins.

They may also attack anything that they perceive as a threat, including guppies. On the other hand, female bettas are less aggressive, especially when not breeding.

Guppies, on the other hand, are peaceful and social fish. They thrive in groups and enjoy swimming together.

Male guppies are known for their colorful and elaborate fins, which may get them into trouble in a tank with a betta. Bettas may mistake their fins for competition and attack them.

Overall, compatibility between the two species depends on the temperament of the betta and the number of guppies in the tank.

Differences and Similarities Between Bettas and Guppies

While bettas and guppies may look similar, there are notable differences between the two species. Bettas are larger than guppies, usually growing up to three inches in length, while guppies only grow up to two inches.

In terms of color, bettas come in a wider range of hues, including red, blue, green, and purple. Guppies are also colorful, but they are limited to a few colors, such as orange, blue, and green.

Both bettas and guppies are carnivorous, but their diets differ slightly. Bettas are insectivores and require a high protein diet.

On the other hand, guppies are omnivores and will eat both plants and animals.

Tank Size and Environmental Considerations

Another crucial factor to consider when keeping bettas and guppies together is the tank size. Bettas require a minimum of five gallons, while guppies can thrive in tanks as small as two gallons.

However, it’s essential to note that larger tanks are always better for the fish’s health and happiness. In addition to tank size, the environment is another critical factor to consider.

Both bettas and guppies require a specific temperature range to thrive. Bettas prefer temperatures between 76-82F, while guppies thrive in temperatures between 72-82F.

Make sure to provide hiding places, such as rocks or plants, in the tank to ensure that both fish can retreat when they feel threatened.

Keeping Betta Fish with Guppies

If you’ve decided to keep bettas and guppies together, here are some essential things to keep in mind.

Choosing the Right Betta

To increase your chances of success, choose a docile variety of betta. Half-moon, crowntail, and plakat bettas tend to be less aggressive than delta or veiltail bettas.

Make sure to introduce the betta to the tank first and let it establish its territory before adding guppies.

Limitations on Betta Quantity

If you have a smaller tank, limit the number of bettas to one. Male bettas should not be housed together, as they will fight each other.

Female bettas can live together, but they may display aggressive behavior during breeding.

Feeding Mixed Tank

Feeding a mixed tank requires careful consideration. Bettas and guppies have different dietary requirements, and you’ll need to make sure that both fish are getting the right nutrients.

You can feed bettas a combination of high-protein pellets and frozen or live insects. Guppies will happily eat flakes and occasional treats like brine shrimp or bloodworms.


In conclusion, bettas and guppies can live together under the right circumstances. However, it requires careful consideration of compatibility, differences and similarities, tank size, and environmental factors.

With proper care and attention, keeping bettas and guppies together can be a rewarding and enjoyable experience.

Guppy Breeding and Tank Management

If you’re considering breeding guppies, there are a few things you should keep in mind. Breeding guppies can be a rewarding experience, but it’s essential to have a clear understanding of the breeding process and how to care for the resulting fry.

Guppy Breeding with Bettas

Breeding guppies with bettas is not recommended, as male bettas are territorial and may attack guppies, especially the males with bright tails. However, some fish keepers have been successful in keeping guppies and bettas together when they have a larger tank, a well-planted environment, and plenty of hiding places.

If you want to breed a specific color or pattern of guppy, consider setting up a separate breeding tank for them.

Overpopulation and Tank Quality

Overpopulation is a common issue in guppy tanks. If left unchecked, it can lead to poor water quality and stress among the fish.

It’s essential to monitor the number of guppies in the tank and ensure that you have adequate filtration to keep the water clean. Use a heater with a thermostat to maintain an ideal temperature range between 72-82F.

When breeding guppies, it is important to have a separate tank for the fry and a well-established filter system. In the early stages, the fry are incredibly fragile and cannot compete with other fish for food.

They require a clean and well oxygenated environment for their growth and development.

Feeding Guppies and Bettas

When feeding guppies and bettas, it’s important to choose high-quality food that can meet their specific dietary needs. Guppies are omnivores and will eat both plants and animals, while bettas are primarily insectivores that require a high-protein diet.

Feed guppies a high-quality flake food supplemented with live or frozen brine shrimp or bloodworms. For bettas, provide a high-quality, low-fat pellet that contains at least 40% protein.

Treat them occasionally with live food, such as brine shrimp or wingless fruit flies. Remember to feed your fish once or twice a day, and remove any uneaten food from the tank within a few minutes.

Overfeeding can lead to poor water quality, which can cause stress and disease in fish.

Conclusion and Advice

In conclusion, keeping guppies and bettas together can be a challenging but rewarding experience. When done correctly, these two species can coexist and even breed together in the right environment.

However, it’s essential to have a clear understanding of their dietary needs, environment, and compatibility. If you plan to keep guppies and bettas together, make sure to have a tank size that can accommodate both species’ needs.

Install a filter system that can handle the fish’s waste production and maintain a consistent water quality. Provide adequate hiding places and plants to mimic their natural habitat.

If you’re considering breeding guppies, remember to have a separate breeding tank for the fry and to carefully monitor the population growth. Overpopulation can lead to poor water quality and stressful conditions for the fish.

Finally, always choose high-quality food that meets the specific dietary needs of your fish and feed them once or twice a day. In summary, proper tank setup, species choice, and careful management are key to maintaining a healthy and happy fish community.

With proper care and attention, guppies and bettas can thrive together and provide endless hours of entertainment for their owners. In conclusion, keeping guppies and bettas together can be a great experience if done correctly.

However, proper tank setup, species choice, and care are necessary to maintain a healthy fish community. Bettas and guppies have different temperaments, dietary needs, and environmental requirements that need to be met to avoid aggression, stress, and disease.

Adequate filtration, proper feeding, and regular monitoring of water quality are essential for their well-being. Finally, always keep in mind that fish-keeping is a hobby, and taking care of living creatures requires responsibility and commitment.

By following these guidelines, you can create a thriving and flourishing aquatic ecosystem that will provide countless hours of delight for you and your family.
