Key Takeaways

– Male bettas are highly territorial and should not be housed with other bettas. Female bettas can live together in groups as long as there are no males present.
– Shrimp, tiger barbs, goldfish, cichlids, gouramis, dwarf pea puffers, rainbow sharks, axolotls, and larger aggressive fish are all unsuitable tank mates for bettas.
– When looking for tank mates for bettas, it is important to choose species with similar water parameter requirements and that produce less waste. Peaceful bottom feeders are a good option.
– Before introducing corydoras as tank mates for bettas, it is important to provide ample hiding spots for the corydoras and monitor aggression levels. Proper water conditions should be maintained for both species.

Other Bettas

You should avoid keeping other bettas with your betta fish. Male bettas are highly territorial and will fight, while female bettas can live together in groups as long as there are no male bettas present.

Male bettas will view each other as competition and will engage in aggressive fights to establish dominance. These fights can result in serious injuries or even death.

Female bettas, on the other hand, have a natural hierarchy and can coexist peacefully in a community tank as long as there are no males around. It is important to note that even though female bettas can live together, they still have individual personalities and may not get along with every female betta.

It is always best to observe their behavior and be prepared to separate them if necessary.


Shrimp can serve as food for your bettas and may not be well-tolerated due to their presence. While most shrimp breeds have similar water requirements as betta fish, bettas do not generally tolerate their presence well. Shrimp, especially smaller ones, can become a tasty treat for your bettas.

It’s important to keep in mind that bettas are known for their aggressive behavior, and they may view shrimp as prey rather than tank mates. To create a peaceful environment for your betta, it is recommended to avoid housing them with shrimp. Instead, consider other suitable tank mates that won’t be seen as a potential meal.

Always research thoroughly to ensure compatibility and provide the best environment for your betta fish.

Tiger Barbs

Tiger barbs are enthusiastic nippers and should be kept separate from fish with long tails and fins. They have a tendency to nip at the fins of other fish, especially those with long, flowing tails. This can cause stress, injury, and even death to the targeted fish.

To ensure the well-being of your other fish, it is important to avoid keeping them with tiger barbs. Instead, consider choosing tank mates that are compatible with the aggressive nature of tiger barbs. Some suitable options include danios, rasboras, and tetras. These fish have similar activity levels and can coexist peacefully with tiger barbs.


When considering tank mates for goldfish, it’s important to choose species that have similar water temperature preferences and produce less waste. Goldfish are cold-water fish and prefer temperatures between 65-75°F. They also produce a significant amount of waste, so it’s crucial to avoid species that are sensitive to poor water quality.

Avoid keeping goldfish with tropical fish that require warmer temperatures, as this can cause stress and health issues for the goldfish. Additionally, avoid species that are sensitive to high levels of ammonia and nitrite, as goldfish produce a lot of waste and can quickly pollute the water.

Good tank mates for goldfish include other cold-water fish like koi, shubunkins, and common minnows. Remember to provide ample space and proper filtration to accommodate the needs of both the goldfish and its tank mates.


If you’re considering adding cichlids to your aquarium, it’s important to research their compatibility with other fish species and their aggressive behavior.

Cichlids are known for their territorial nature and can be quite aggressive towards other tank mates. Here are some reasons why cichlids may not be suitable tank mates for betta fish:

– Aggressive Behavior: Most cichlid species exhibit aggressive behavior, which can lead to stress and injuries for the betta fish.

– Territorial Nature: Cichlids are highly territorial and may not tolerate the presence of other fish in their space, including bettas.

– Different Water Requirements: Cichlids have specific water parameter requirements that may not align with the needs of bettas.

– Size Difference: Some cichlids grow larger than bettas, which can result in bullying and potential harm to the betta.

It’s crucial to consider these factors before introducing cichlids into your betta fish tank to ensure the well-being of all the inhabitants.


Consider providing ample hiding spots and separate tanks for gouramis and bettas due to their territorial nature and potential conflicts.

Gouramis, like bettas, belong to the same family and share similar aggressive tendencies. It is important to create a peaceful environment for both species to thrive.

Gouramis are known for their vibrant colors and peaceful nature, but they can become territorial when housed with bettas. This can lead to stress, aggression, and even injuries.

To avoid these issues, it is best to keep gouramis and bettas in separate tanks with enough hiding spots to alleviate any potential conflicts.

Dwarf Pea Puffer

To successfully house a dwarf pea puffer with your betta, ensure you provide enough space and hiding spots for both species. Creating a harmonious environment is crucial for the well-being of your fish. Here are some key points to consider:

– Tank Size: Provide a tank that is at least 10 gallons to accommodate the territorial nature of both the betta and the dwarf pea puffer.

– Hiding Spots: Incorporate plenty of hiding spots, such as caves, plants, and driftwood, to give both species a sense of security.

– Water Parameters: Maintain suitable water parameters, including temperature, pH, and hardness, that are compatible for both the betta and the dwarf pea puffer.

– Feeding: Offer a varied diet to meet the specific nutritional needs of both species, ensuring they receive appropriate nutrition.

Rainbow Shark

Ensure you provide ample space and proper tank conditions for a peaceful coexistence with a rainbow shark. Rainbow sharks are territorial and aggressive, so it’s essential to create a suitable environment to minimize conflicts.

These beautiful fish require larger tanks with a minimum capacity of 55 gallons. They can grow up to 6 inches in length and need plenty of swimming space. Decorate the tank with rocks, caves, and driftwood to create hiding spots and territorial boundaries.

Rainbow sharks prefer a temperature range of 72-79°F and a pH level of 6.5-7.5. Avoid housing rainbow sharks with slow-moving or long-finned fish, as they may see them as potential targets.

Proper research and careful consideration of tank mates are crucial for maintaining a harmonious aquarium environment.


Now that you’re aware of the incompatibility between bettas and Rainbow Sharks, let’s move on to another unsuitable tank mate for betta fish: the Axolotl.

Axolotls: Axolotls are unique aquatic creatures that are popular among aquarium enthusiasts. However, they are not ideal tank mates for bettas. Axolotls have delicate external gills and can be easily injured by the betta’s sharp fins. Additionally, bettas are known to nip at the gills of axolotls, causing them stress and potential harm.

Due to the size difference and their differing habitat requirements, it’s best to keep bettas and axolotls in separate tanks to ensure the well-being of both species.

Other Incompatible Tank Mates

Research thoroughly to find suitable companions for your betta fish. This will help create a peaceful and harmonious aquarium environment. It is important to avoid incompatible tank mates as they may cause aggression and stress for your betta.

Some species that should not be housed with bettas include:

– Other bettas (male bettas are highly territorial)
– Shrimp (which can become food for bettas)
– Tiger barbs (known for their nipping behavior)
– Goldfish (due to their different water temperature preferences and waste production)
– Cichlids (known for their territorial and aggressive behavior)
– Gouramis (which are highly territorial like bettas)
– Dwarf pea puffers (both small and aggressive)
– Rainbow sharks (territorial and aggressive)
– Axolotls (fragile and intolerant of other tank mates)
– Other larger aggressive fish like turtles, discus fish, Oscars, and African cichlids.

Finding the Ideal Tank Mate

To create a harmonious aquarium environment, consider seeking out tank mates for your betta fish that have similar water parameter requirements and produce less waste. Finding the ideal tank mate for your betta can be a challenging task, but with proper research and consideration, you can ensure a peaceful coexistence. Here are some tips to help you in your search:

– Seek species with similar water parameter requirements and produce less waste.
– Choose peaceful tank mates to avoid conflicts and fights.
– Bottom feeders are a good option as they tend to stay away from bettas.
– Research thoroughly to ensure compatibility with bettas.

Betta Fish & Corydoras

Can corydoras and bettas peacefully coexist in the same tank?

The compatibility between bettas and corydoras depends on the specific species of each fish. While bettas are known for their territorial nature, many corydoras species are peaceful bottom dwellers.

Providing ample hiding spots for the corydoras can help reduce aggression from the betta. It is important to monitor the aggression levels in the tank and separate the fish if necessary.

Maintaining proper water conditions, including temperature and pH, is essential for the well-being of both species. By following these guidelines, you can create a harmonious tank environment where bettas and corydoras can coexist peacefully.

How to Treat White Fungus on Corydoras

Now that you have learned about the compatibility between betta fish and corydoras, let’s discuss how to treat white fungus on corydoras.

It is important to address this issue promptly to ensure the health of your corydoras. Here are some steps you can take:

Maintain clean water conditions: Poor water quality can contribute to the development of white fungus. Perform regular water changes and keep the tank clean.

Use appropriate medications: There are medications available specifically for treating fungal infections. Follow the instructions carefully and administer the medication as directed.

Quarantine infected corydoras: To prevent the spread of the fungus to other fish, it is best to isolate the infected corydoras in a separate tank.

Seek professional advice: If the white fungus persists or if you are unsure about the best course of action, consult a veterinarian or an experienced fish keeper for guidance. They can provide specific recommendations based on the severity of the infection.
