FAQ

How often should I feed my arowana?
Arowanas should be fed once or twice daily, depending on their size and age. Juveniles need more frequent feeding, while adults can thrive with smaller, controlled portions. High-protein foods such as shrimp, worms, and specialized pellets are ideal. Avoid overfeeding, as uneaten food can pollute the tank and cause health problems. Monitor their appetite and adjust feeding amounts accordingly. Feeding in the evening is common since arowanas are often more active at that time. Variety in diet also helps maintain vibrant coloration and overall health.

What tank size is ideal for arowanas?
Tank size depends on the variety and adult size of the arowana. Most require at least 250 gallons, with taller tanks preferred for jumping prevention. Ample swimming space is essential, as arowanas are active and can grow over three feet. Tanks should have secure covers, strong filtration, and consistent water parameters. Long-term growth and health depend on providing an environment that supports natural movement and reduces stress. For smaller varieties like Jardini arowanas, slightly smaller tanks may suffice, but adults still need room to swim comfortably.

Can arowanas live with other fish?
Arowanas can live with other fish, but careful selection is required. They are territorial and may attack smaller or slow-moving tank mates. Choose similarly sized, robust species to avoid conflicts. Providing hiding spots and monitoring interactions can reduce aggression. Juvenile arowanas are sometimes more adaptable but still require careful observation. Avoid overcrowding, as it increases stress and competition for food. Compatibility depends on temperament, tank size, and feeding habits. Gradual introductions and sufficient space help create a more peaceful community.

How do I maintain water quality for arowanas?
Maintaining stable water conditions is essential for arowana health. Regular water changes, usually 25–30% weekly, help remove waste and prevent ammonia buildup. Filtration must be strong, and water parameters such as temperature (75–82°F), pH (6.5–7.5), and hardness should be monitored consistently. Avoid sudden changes in water chemistry, as arowanas are sensitive to fluctuations. Testing kits and careful observation of fish behavior can indicate when adjustments are needed. Proper aeration and avoiding overcrowding also contribute to water stability.

What health issues should I watch for?
Common health concerns include fin rot, swim bladder issues, and parasites. Poor water quality often triggers these problems, so maintaining clean conditions is critical. Uneaten food, overcrowding, or incompatible tank mates can increase stress and susceptibility to disease. Signs of illness include lethargy, loss of appetite, unusual swimming patterns, or faded coloration. Quarantining new fish before introducing them reduces the risk of spreading disease. Regular observation and timely treatment with appropriate medications can prevent serious health problems.

How do I enhance arowana coloration?
A balanced diet with high-protein foods supports vibrant scales. Including live or frozen shrimp, crickets, and specially formulated pellets enhances color intensity. Consistent lighting and optimal water conditions also improve coloration. Avoid stress, as it can dull colors. Gradual improvements in diet and tank care yield the best results. Supplements designed for coloration can be used sparingly.

How long do arowanas live?
With proper care, arowanas can live 10–20 years or longer. Lifespan depends on variety, diet, tank conditions, and health management. Consistent care, stable water parameters, and attention to diet are key factors for longevity. Their long lifespan requires commitment but allows for years of enjoyment observing their growth and behavior.

Do arowanas jump out of tanks?
Yes, arowanas are strong jumpers. Secure covers are essential to prevent accidents. Avoid sudden disturbances near the tank and provide a calm environment. Ensuring the tank has adequate height and smooth surfaces reduces injury risk. Jumping behavior is more common in younger, more active fish.

Can I breed arowanas at home?
Breeding arowanas is challenging and requires large, well-maintained tanks. Pairing compatible male and female fish is necessary, along with careful observation of courtship behaviors. Maintaining perfect water quality and providing high-protein foods supports breeding success. Many home aquarists focus on keeping healthy adults rather than breeding, as it is complex and space-intensive.

How do I handle arowanas safely?
Minimize handling to reduce stress. Use soft nets and avoid lifting them by the gills or body. Always have a secure tank environment to prevent jumping. Handling is best limited to tank maintenance or emergency situations. Proper handling preserves both fish health and your safety.

Arowanas are among the most striking freshwater fish, offering vibrant colors and graceful movements that make them captivating additions to large aquariums. Each variety, from Asian to Platinum, brings unique features, coloration, and size that appeal to different aquarists. While they are visually impressive, owning an arowana comes with a significant level of responsibility. Their large size, active swimming habits, and sensitivity to water conditions mean that proper tank setup, regular maintenance, and a carefully balanced diet are essential. Understanding the characteristics of each variety can help ensure that the fish you choose will thrive in your aquarium. They are long-lived fish, which allows owners to enjoy their presence for many years, but this longevity also requires consistent care and attention. Investing in quality filtration, adequate tank space, and monitoring water parameters like pH and temperature is crucial. Without these measures, even the most beautiful arowana can become stressed, leading to health problems and reduced coloration.

Feeding arowanas is another important aspect of their care. A balanced diet consisting of high-protein foods, such as live shrimp, insects, or specialized pellets, supports both their growth and coloration. Overfeeding should be avoided, as leftover food can affect water quality and cause health issues. Juvenile arowanas require more frequent feeding, while adults do well with controlled portions once or twice a day. Consistency in feeding and monitoring the fish’s appetite helps maintain their overall health. Observing their behavior during feeding can also provide insights into their well-being and detect early signs of stress or illness. Additionally, providing a variety of foods not only enhances their color but also encourages natural hunting behaviors. These steps, combined with clean water and a stress-free environment, create the conditions needed for an arowana to thrive, maintaining its vibrant scales and graceful movements over time.

Choosing the right arowana also means considering space, temperament, and tank compatibility. Some varieties are more territorial and aggressive, so tank mates must be selected carefully to prevent conflicts. Large, spacious tanks with secure covers are necessary to accommodate their jumping behavior and active swimming. Lighting, water quality, and environmental enrichment, such as hiding spots or smooth surfaces, all contribute to reducing stress and promoting natural behavior. While arowanas require dedication and attention, they can be incredibly rewarding for those willing to meet their needs. Their elegance and presence make them a striking centerpiece, and with proper care, they can live long, healthy lives. Understanding their requirements, committing to consistent maintenance, and providing appropriate nutrition are the foundation for successful arowana ownership, ensuring these impressive fish remain vibrant and active for many years.
