Siamese Fighting Fish or Betta Fish: What You Need to Know
Siamese Fighting Fish, or Betta Fish, are captivating and popular freshwater aquarium species. Known for their aggressive nature and majestic fins, they belong to the Osphronemidae family. Betta fish are territorial and possessive, guarding their space with ferocity.
Wild and captive-bred Bettas differ in color and tail designs. Their lifespan is relatively short, around two to four years, and they primarily feed on insects. Male Bettas are incompatible with other males but can coexist with females during breeding. Female Bettas generally have better compatibility.
Understanding these traits helps provide proper care for these fascinating fish.
Betta Fish Compatibility: Male vs Female Betta Fish
It’s important to note that placing two male Betta fish together in a single bowl will inevitably lead to aggressive behaviors. However, the dynamics change entirely when it comes to female Betta fish.
Unlike their male counterparts, female bettas can coexist harmoniously with one another without any need for separation. There is generally no fighting or aggression among female bettas.
Keep in mind that betta fish breeding should only be conducted in captivity. It is crucial to closely observe the female betta’s response to the male betta’s mating behaviors to ensure a healthy breeding process.
1; Setting up the Breeding Betta Fish Tank
When it comes to breeding Betta fish, it’s crucial to understand that a single wrong step can have dire consequences for your beloved fish.
Just like any other natural process, betta fish breeding follows a specific cycle that requires careful attention and understanding.
Creating an optimal tank setup not only enhances the overall health of your fish but also plays a vital role in facilitating a successful betta fish breeding process.
How to Set up Your Permanent Betta Tanks
While many fish keepers may already possess these items, here is a comprehensive list of all the essential equipment to breed fighting fish at home you’ll require:
Essential betta fish breeding equipment:

- Keep the bettas in separate tanks until it’s time to breed to prevent any harm or aggression.
- Maintaining high water quality is crucial, so regularly test the water using a kit and address any issues such as ammonia levels, acidity, pH, or oxygen saturation.
- Maintain a temperature range of 50-78 degrees Fahrenheit and use a gentle water filter to control waste while avoiding excessive water movement that may disturb the bettas.
- Create hiding spots with plants to reduce female stress and protect the bubble nest of eggs, utilizing floating plants to enhance the breeding environment.
This process ensures optimal water quality and prepares the tanks to support the well-being and breeding of the bettas.
2. How to Choose Successfully Betta Breeding Pair
Choosing a successful breeding pair of bettas requires the following steps:
- Find a reputable breeder: Look for a trusted breeder online or in your area who specializes in betta breeding. They can provide healthier and genetically diverse bettas compared to pet store fish.
- Seek guidance from the breeder: A knowledgeable breeder can offer valuable advice and insights into successful breeding. They can guide you on selecting compatible pairs and provide information on their lineage and health history.
- Consider age and size: Opt for young bettas as they have higher breeding potential. Choose a male and female that are similar in size to ensure a balanced pairing.
- Get multiple pairs: It’s a good idea to have multiple pairs of bettas in case the first pairing doesn’t result in successful breeding. This allows you to try different combinations and increase the chances of a successful match.
- Avoid breeding pet store bettas: Pet store bettas are often inbred and prone to genetic and health issues. It’s best to avoid breeding them to ensure the health and quality of the offspring.
By selecting a reputable breeder, obtaining bettas of suitable age and size, and avoiding pet store fish, you can increase the likelihood of a successful breeding experience with healthier and genetically diverse bettas.
3. How to Select a Male Betta in Betta Breeding
Increase your chances of choosing a desirable male by following these guidelines:
- Energy Levels: Look for a male betta with high energy and vigor. A lack of energy may indicate a weak immune system, which can be heritable. Female bettas instinctively seek males with strong immune systems for healthier offspring.
- Coloration: Opt for males with vibrant colors, particularly red. Bright colors suggest that the male has consumed enough carotenoids to support his immune system and overall health. Studies have shown that female bettas are more attracted to red males, as it indicates good immune system genes and robust health.
- Fins: Healthy and undamaged fins are important indicators of a male’s overall health. Males with strong immune systems and successful foraging skills will have fins that heal quickly from minor injuries. Females are more likely to be attracted to males with long, intact fins, as it signifies their strength and good health.
By considering these factors when selecting a male betta, you can improve the chances of successful breeding and ensure the production of healthy offspring.
4. How to Create the Breeding Conditions for Betta Fish
Separate the male and female:
Betta fish reproduce through a process called spawning, which involves the male and female bettas engaging in a specific breeding procedure.
Keep the male and female bettas in separate tanks to prevent any aggressive behavior or stress. This allows them to focus on building their strength and preparing for breeding.
Let them settle in:
Give your bettas a few months to adapt to their environment before attempting to breed them. However, keep in mind that male bettas breed best when they are no older than 14 months. Choose a time for breeding when you have a long, uninterrupted period of free time and avoid upcoming vacations, business trips, or stressful events.
Prepare the breeding tank:
Set up a breeding tank that is 5-10 gallons (18.9-37.9 L) in size. Equip it with a removable divider, hiding places, an adjustable filter (such as a sponge filter with a gang valve), and a heater set to around 80 °F (27 °C). Avoid adding gravel or substrate to the tank as it may cause the eggs to be lost. Keep distractions to a minimum, such as other fish, bright colors, and human activity.
Introduce live food:
When your betta is ready to breed, start feeding your bettas live food. Live brine shrimp or bloodworms are ideal choices, but other small live organisms like worms, crickets, or insects (cut up) can also be used. It is recommended to raise these food sources yourself or obtain them from reputable sources to ensure cleanliness and avoid potential risks from wild insects. Frozen or freeze-dried brine shrimp and bloodworms can be alternatives if live food is unavailable.
Prepare fry food:
Betta fry requires very little live food, so it’s essential to have a ready supply. Start cultivating micro worms, infusoria, or vinegar eels in advance. These are suitable options for feeding the fry. Baby brine shrimp can also be included in their diet but should be provided in moderation alongside another food source to prevent swim bladder disorder.
Observe their behavior:
Watch the bettas closely to assess their interest in one another. The male will display vibrant fins, and flare, and engage in showing off behavior. The female, on the other hand, will exhibit vertical bars on her body and submissive head angling. While some aggression is normal, if they continuously flare and attempt to attack each other through the divider, it is best to separate them and try again later or with a different pair of bettas. Patience and observation are key during this stage of the breeding process.
5. How to Introduce Your Male Betta to Female Betta to their Breeding Tank
Introduce the betta mates by following these steps. After ensuring the health and feeding of each betta, begin by placing them in separate tanks near each other for a couple of days to allow them to familiarize themselves and prevent any potential harm or damage.
Look for signs of interest between the bettas during this period, indicating their readiness to mate.
Next, place a divider in the tank, creating separate sides. Position the female Betta on one side and, half an hour later, place the male Betta on the other side.
The male betta will display enhanced fin colors to attract the female’s attention. Watch for the female’s response with a similar display of enhanced fin colors.
Within twenty-four hours, you’ll notice the male betta starting to build a bubble nest on top of the almond leaf you had previously placed in the tank.
6. Mating Your Bettas
Once your breeding pair has been conditioned for 10 days, it’s time to add your female and male to the breeding tank.
Introduce your male betta to your female in a breeding net to ensure their acclimation and minimize stress. Take care not to disturb the tank, as the male will begin building a bubble nest under floating debris where he will guard the eggs. The female should wait for the bubble nest and allow it to grow for about three days until enough eggs have been produced. For privacy, consider covering the tank with paper or plastic to avoid scaring or distracting the pair from breeding.
It’s Time to Remove the Breeding Tank Divider
Removing the Breeding Tank Divider and Starting the Breeding Process
Once you have followed the conditioning process for your breeding pair for a period of 10 days, it is time to introduce them in the breeding tank. For a step-by-step guide, follow these steps:
1. Remove the divider and release the female:
If everything appears to be in order, remove the divider from the breeding tank. At this point, the male and female bettas will exhibit aggressive behavior toward each other. The male may chase the female into hiding, and there may be fin nipping and tearing. It is important to closely monitor their interactions during this period, as there have been instances of the male-killing the female. Keep the aquarium lights on continuously for now.
2. Check for breeding readiness:
Make sure that the following signs are present in both the male and female bettas before proceeding: substantial bubble nest growth, vertical bars displayed by the female, a plumper body indicating full eggs, the presence of a small white egg tube on the female’s abdomen, and the female swimming with her head down in a submissive manner. If any of these signs are missing, give them another day to show the necessary readiness indicators. If after a week there are still no signs, repeat the conditioning process for two weeks and start again.
3. Ensure bubble nest presence:
If the second breeding attempt lacks a bubble nest, replace the male betta with another one. This nest serves as a crucial element in the breeding process.
4. Duration of aggressive phase:
The aggressive phase should last around 2-3 days. If it extends beyond this period without any signs of breeding, remove both bettas from the tank and attempt again after a 2-week interval. Once the aggressive phase subsides, the actual breeding process will begin.
7. Egg-Laying and Fry Development
- Submissive behavior and egg release: After the aggressive phase concludes, the female will swim towards the male with her head down, displaying submissive behavior. The male will attempt to wrap his body around the female, trying different angles until successful. Once they find the right position, they will sink to the bottom while embracing, and the female will release her eggs while the male fertilizes them.
- Males care for the eggs: The male betta will pick up the eggs with his mouth and transfer them to the bubble nest. He will continuously monitor and maintain the nest, repairing it by blowing new bubbles. During this time, it is advised not to feed the male or to provide very small portions to avoid water pollution.
- Waiting for hatching: The eggs will take approximately 36-72 hours to hatch. As they develop, small black dots (the eyes) will become visible on the eggs. It is normal for the male to eat unfertilized or decaying eggs during this stage.
- Possible complications: There are two potential issues that may arise at this point. The male may eat all of the eggs, or he may abandon the nest, causing the eggs to fall and the nest to collapse. If either of these scenarios occurs, it is recommended to remove the male and salvage any remaining eggs, although the chances of survival are low.
8. Fry Hatching Process
As the fry continues to develop, you will notice significant changes in their appearance and behavior.
- During the first few days after hatching, the fry hangs tail-down, relying on yolk sacs for nourishment. In this period, they gradually absorb the yolk sac and develop the ability to swim horizontally.
- As they become more active and gain strength, the fry will start to swim freely in the tank. This marks an important milestone in their development, indicating their readiness for independent feeding.
- At this stage, it is recommended to remove the male betta from the tank to prevent any potential aggression toward the fry.
- To meet their nutritional needs, provide the fry with suitable food options such as small brine shrimp, micro worms, vinegar eels, or infusoria. These tiny live foods will support their growth and ensure they receive the necessary nutrients.
- Continue to observe the fry closely, ensuring they are feeding and swimming actively. Maintain a suitable environment by keeping the tank clean and providing appropriate water conditions.
- As the fry grows, you can gradually introduce other suitable food options to diversify their diet and promote healthy development.
Remember to monitor the fry’s progress, adjust their feeding schedule as needed, and provide them with a conducive environment to thrive.
