The Silver Arowana is a majestic fish known for its impressive size and striking appearance. Native to the Amazon River Basin, it is often called the Dragon Fish or Monkey Fish because of its long body and barbels that resemble dragon whiskers. This is a highly predatory species that requires ample space, specialized care, and attention to water quality to thrive in captivity.

Size & Appearance

Silver Arowanas can grow up to 3 feet (90 cm) in length in captivity, with some even reaching 4 feet in the wild. Their body is long, slender, and band-like, with a small tail fin and extended dorsal and anal fins. The pearlescent silver body and unique features like vertical mouths and barbels contribute to their stunning look.

Care & Maintenance

Silver Arowanas require large tanks—at least 250 gallons for adults. As juveniles, they can start in smaller tanks, but they grow rapidly, often reaching 2 inches per month during their first year. A tank with ample swimming space is essential to prevent stress and developmental issues. Secure lids are vital because these fish are known to jump.

The water temperature should stay between 75°F to 82°F with a pH ranging from 5.0 to 7.5. Regular water testing and maintenance are crucial to keep ammonia, nitrate, and nitrite levels in check, with weekly water changes recommended.

Feeding

These carnivorous fish eat live or frozen foods such as feeder fish, shrimp, earthworms, and crickets. Dried pellets are not sufficient for their diet. A diet rich in protein helps maintain their health and ensures they grow strong.

Behavior & Tank Mates

Silver Arowanas are aggressive and territorial, especially as they grow. They will often try to eat any fish that can fit in their mouths. For tank mates, large, aggressive fish such as catfish, Pacu, or large cichlids may work. However, pairing them with other Arowanas is not recommended unless the tank is very large.

Breeding

Breeding these fish in captivity is rare. They are mouthbrooders, where the male carries the fertilized eggs in his mouth for up to 50 days. After hatching, the fry will stay in the male’s mouth for about 5 weeks before being released into the tank.

Challenges

• Diseases: Silver Arowanas are prone to diseases like Ich, fin rot, and Dropsy, particularly in stressful environments.
• Space: These fish grow very large, and insufficient tank space can cause physical deformities or stress.

Conclusion
Silver Arowanas are spectacular fish but require dedicated care. For those with the right setup and commitment, they can thrive and live for 10-15 years, becoming a prized addition to any large aquarium.
