Distinctive Appearance

The Silver Arowana has a long, streamlined body covered in large, reflective silver scales. Its elongated dorsal and anal fins extend towards the tail, creating a smooth, flowing silhouette as it swims. Two short barbels near the mouth help distinguish this species and contribute to its characteristic appearance.

Behaviour and Natural Characteristics

Silver Arowanas are powerful swimmers and surface-oriented predators that naturally hunt near the water's surface. They can leap out of the water when pursuing prey or reacting to disturbances, making a strong, tightly secured aquarium lid essential. Their large adult size and predatory behaviour require careful consideration when selecting tank mates.

Feeding and Nutrition

Silver Arowanas require a varied, species-appropriate carnivorous diet. Suitable foods may include appropriately sized fish pellets formulated for large predatory fish, insects, and other suitable animal-based foods. Feed portions appropriate to the fish's size and avoid relying on feeder fish, which can introduce parasites or disease.

Aquarium Environment

A Arowana requires a very large aquarium with substantial swimming length, excellent filtration, stable water conditions, and a secure lid. Because adults can exceed three feet, a typical small home aquarium is unsuitable for long-term housing. Tank dimensions and filtration should be planned for the fish's adult size rather than its juvenile size.

Why Choose a Silver Arowana?

With its metallic scales, distinctive body shape, and commanding swimming style, the Silver Arowana is a striking choice for experienced fishkeepers with the space and resources to accommodate a large predatory fish. Its impressive appearance makes it a standout species in a suitably designed aquarium.
