Arowana, also known as the "Dragon Fish," is famous for its sleek body and shimmering scales. This fish is quite popular among aquarium enthusiasts. If you want to breed Arowanas, it can be a challenging yet rewarding experience.
Types of Arowanas and Breeding Conditions
First, it is important to understand that there are several types of Arowanas. The most popular species include:
Asian Arowana (Scleropages formosus)
Silver Arowana (Osteoglossum bicirrhosum)
Jardini Arowana (Scleropages jardini)
Each species has slightly different breeding requirements, but the basic principles remain the same.
Arowanas are egg-layers, and their breeding can occur both naturally and artificially. However, captive breeding can be a bit more challenging. In the wild, these fish reside in slow-moving rivers and lakes and can grow to a large size (up to 3 feet).
2. How to Create the Breeding Environment?
To breed Arowanas, their environment needs to closely mimic their natural habitat. Here are some key factors to consider:
Tank Size and Setup:
Arowanas are large fish, so a minimum tank size of 300 gallons (1135 liters) is required. This will provide enough swimming space for the fish.
Keep the water flow low, as Arowanas naturally reside in slow-moving waters.
The tank can include rocks, driftwood, and plants, but avoid overcrowding to ensure the fish have ample space to move.
Water Conditions:
Temperature: Arowanas prefer warm water, so the water temperature should be between 80°F and 86°F (27°C to 30°C).
pH: The water's pH should be slightly acidic to neutral (6.5 to 7.5).
Hardness: Soft to moderately hard water is ideal.
Water Quality: Arowanas are sensitive to water quality, so regular water changes (25-30% weekly) and a strong filtration system are essential.
Lighting:
Arowanas require low to moderate lighting. You can use LED lights that mimic the natural daylight spectrum.
3.How to Choose Healthy Breeding Pairs?
Breeding Arowanas is a challenging process, and the first and most important step is selecting a healthy breeding pair. Choosing the right pair increases the chances of successful breeding.
Selection of Mature Fish:
Arowanas take time to become sexually mature. Therefore, when selecting fish for breeding, ensure they are fully mature.
Age: Arowanas typically reach sexual maturity around 2-3 years, but this can vary depending on the species. Both Asian Arowanas and Silver Arowanas have similar maturity periods.
Size: Generally, the female Arowana is slightly larger than the male. Mature fish typically range from 18 to 24 inches in size.
Health and Physical Condition Check:
The health of the breeding pair is crucial for successful spawning. You should check the overall health and physical condition of the pair:
Body Condition: The fish should have a healthy and muscular body. If the fish appears thin or has any deformities, it may not be suitable for breeding.
Coloration: Healthy Arowanas have vibrant and bright colors. Faded or dull coloration could indicate stress or illness, which may hinder breeding.
Fin Condition: The fins should be clean, intact, and free from damage. Damaged or torn fins may indicate that the fish is stressed or injured.
Observation Of Breeding Behavior:
Observing the behavior of the Arowanas is also important, as certain signs indicate readiness for breeding:
Male Behavior: When the male Arowana is ready to breed, he will spread his fins and tail to try to impress the female. He may also become more territorial and perform swimming motions near the female.
Female Behavior: The female Arowana will follow the male and show interest in his actions. If the female seems uninterested, it may indicate that she is not ready or that the pair is not compatible.
Compatibility and Temperament:
Arowanas are highly territorial fish, and not every male-female pair is compatible. Selecting a compatible pair for breeding is crucial, as otherwise, the chances of aggression increase.
Compatibility Check:
When introducing a new male and female to the tank, observe their behavior for some time. If both fish coexist peacefully and show no signs of aggression, this could be a sign of compatibility.
Separate Tank Testing:
If there are compatibility issues within the pair, consider keeping them in separate tanks for observation and then reintroducing them later. Sometimes, with time, the fish become more compatible.
Monitor Breeding Cycle and Time :
It is important to pay attention to the ideal timing and season for breeding. In the wild, Arowanas are seasonal breeders, but in captivity, with proper conditions, they can breed at any time.
Ideal Conditions:
Maintaining stable tank temperature and water quality is crucial for breeding. If the fish are provided with conditions similar to their natural habitat, it can activate their breeding cycle.
Monitor Behavioral Changes:
If you notice any behavioral changes in the fish, such as increased aggression or specific fin movements, it could be an indication that they are ready for breeding.
Quarantine and Disease Prevention:
Before breeding, it’s important to quarantine the fish to ensure that they are healthy and disease-free.
Quarantine Period:
If you’re introducing new fish, they should be kept in a quarantine tank for at least 2-4 weeks. This helps detect any diseases before they can spread to other fish.
Disease Signs:
During the quarantine period, check the fish for any abnormalities in their body or behavior, such as ich, fungal infections, or fin rot. A healthy pair increases the chances of successful breeding and the survival rate of the fry.
4. Breeding Process :
The breeding process of Arowana fish is fascinating and unique due to their natural breeding behavior and unusual parental care. If you are interested in breeding Arowanas, it's important to understand the steps involved in the process.
Courtship Behavior And Pair Bonding:
When Arowana pairs are ready to breed, they exhibit courtship behavior, which is essential for their bonding and successful breeding.
Male Behavior: The male Arowana spreads its fins and tail while swimming, showcasing its best movements to attract the female.
Female Response: If the female is interested, she will closely follow the male. The two fish swim together in a specific area, forming a bond.
During courtship, the male and female chase each other and swim in circular patterns, which is an indicator of their breeding readiness

Spawning Site Selection:
Arowanas naturally lay their eggs in shallow and calm waters, and it's important to simulate this environment in the tank.
Spawning Platform: You can place a flat surface or floating platform (like a flat piece of wood) in the tank where the female can lay her eggs.
Area Cleanliness: Ensure there is no debris or dirt in the tank to keep the eggs safe. Clean water is crucial for the survival of both the eggs and the fry.
Egg Laying (Spawning Process):
During the egg-laying process, the female releases her eggs, and the male immediately fertilizes them. This process is quick and careful.
Egg Laying: The female Arowana typically lays 20-50 large eggs, which are golden-yellow in color. These eggs are large enough to accommodate the developing embryo.
Egg Fertilization: The male fertilizes the eggs immediately after they are released. The fertilized eggs are rich in protein and nutrients, which are essential for the developing fry.
5.Incubation and Hatching Process :
Arowanas have a unique behavior where the male fish holds the eggs in its mouth. This process is called mouthbrooding, and it is crucial for the protection of the eggs and fry.
Mouthbrooding:
Post-Fertilization: Immediately after fertilization, the male holds the eggs in his mouth and incubates them. During this period, the male does not eat and carries the eggs while swimming.
Incubation Duration:
The incubation period typically lasts for 50-60 days. During this time, the male fish provides oxygen and protection to the eggs.
Protective Nature:
The male Arowana becomes very protective of the eggs and fry, and may become aggressive to defend them from any external threats. This protective instinct ensures the safety and survival of the developing fry.
Hatching of the Eggs
After the incubation period, the eggs begin to hatch, and small fry emerge from the male’s mouth.
Hatching Process: Once the embryos are fully developed, the eggs crack open, and the fry emerge. Initially, these fry are very small and have an attached yolk sac, which provides them with extra nutrients to survive during their early days.
Yolk Sac Absorption: After hatching, the fry absorb nutrition from their yolk sac, which serves as their food supply for the first few days. The yolk sac is rich in essential nutrients that support their growth and development.
Early Independence: After a few days, the fry begin to become more independent and attempt short swims. However, if they sense danger or a threat, they quickly return to the male’s mouth for protection.
Protection by Male: The male continues to protect the fry from external threats and stress. If any disturbance or predator approaches, the male fish shelters the fry by taking them back into his mouth, ensuring their safety.
6. Separating and Raising Arowana Fry
Successfully raising Arowana fry is a crucial part of the breeding process. Once the fry are released from the male Arowana’s mouth and become independent, it is important to move them to a separate tank and provide them with the proper care. Since the fry are sensitive, following specific steps to maintain their growth and health is essential.
Shifting Fry to a Separate Tank
After the male Arowana releases the fry from his mouth, it is recommended to move them to a grow-out tank where they can safely grow with enough space. Initially, you can keep the fry in a 20-30 gallon tank, but as they grow, you will need to increase the tank size accordingly.
Ensure the tank has a gentle filtration setup that provides fresh oxygen and clean water without creating a strong current. Low-flow sponge filters or air-driven filters are ideal for this stage.
Lighting: Fry should be kept in low lighting conditions. Avoid direct bright light, as it can cause stress and discomfort for the young fish.
Water Quality And Temperature :
Maintaining stable and clean water quality is essential for the health and growth of Arowana fry. The tank temperature should be kept between 80°F and 82°F (27°C to 28°C), as warm water helps to boost the fry's metabolism and supports their overall growth. Additionally, the water's pH level should be slightly acidic to neutral, ideally ranging from 6.5 to 7, as fry are sensitive to extreme pH levels, which can cause stress and hinder their development. To ensure high water quality, it is recommended to perform weekly water changes of 20-25%. This routine helps to maintain a clean and healthy environment for the fry, promoting optimal growth and reducing the risk of diseases.
Diet Aur Feeding Routine Of Fry :
Providing the right diet is crucial for the rapid growth of Arowana fry. In their early stages, live foods such as brine shrimp and daphnia are ideal, as they are rich in protein and easy to digest. These foods support the fry’s initial growth and development. It is important to feed the fry 3-4 times a day in small portions to prevent overfeeding and maintain a clean tank. As the fry grow, their diet can be gradually expanded to include crushed pellets, bloodworms, and small feeder fish. These additional food options provide variety and ensure the fry receive the necessary nutrients for healthy growth. By offering high-quality, fresh food and following a consistent feeding routine, you can help your Arowana fry grow rapidly and thrive.
Monitoring Growth And Health
Regular monitoring of the fry's growth and health is essential to ensure they are developing at the proper rate and not facing any health issues. One key aspect to watch for is size differences among the fry. Sometimes, some fry grow faster and may dominate smaller fry. In such cases, it's a good idea to separate the smaller fry into another tank to avoid stress or aggression. Additionally, keep an eye on their swimming behavior, color, and eating habits. If any fry appears lethargic or its color appears dull, it could be a sign of stress or disease. Since fry are highly susceptible to diseases, maintaining a clean tank and providing high-quality food are important for preventing the spread of illnesses and ensuring the overall health of the fry.
Tank Upgrade For Growth
Arowana fry grow rapidly, so upgrading their tank to accommodate their increasing size and comfort is necessary. When the fry reach around 3-4 inches in length, it is recommended to transfer them to a larger tank, such as a 100-150 gallon tank. This provides them with enough space to swim and continue growing healthily. Along with tank size, it's important to monitor the compatibility of the fry in the new tank. Arowanas are territorial fish, and larger fry may display aggressive behaviors. If aggression is observed, it is best to separate the more dominant fry to reduce stress and prevent potential harm. This careful monitoring of growth and tank environment will ensure the fry thrive and continue their healthy development.
Arowana breeding and fry raising is a process that demands patience and dedication, but the rewards are well worth the effort. By ensuring proper care, maintaining clean water, and providing nutritious food, you give your Arowana fry the best chance for a healthy start. Though the process can be challenging, witnessing the growth and flourishing of your fry is a unique and deeply satisfying experience. With the right approach, you can successfully raise healthy Arowanas, and enjoy the beauty of watching them develop into strong, vibrant fish.
