Silver Arowana - 10 inch

Silver Arowana is one of the most iconic monster fish in the aquarium hobby, admired for its sleek silver body, powerful swimming style, and dramatic top-dwelling behaviour. A 10 inch specimen already has a commanding presence and is best suited for hobbyists who can provide a large tank, stable water quality, and a well-planned feeding routine. This species is native to the Amazon basin and is known for its alert nature and graceful movement across the upper level of the aquarium.

As a fast-growing predatory freshwater fish, Silver Arowana does best in a spacious setup with excellent filtration and a tightly fitted lid. It is often chosen as a centerpiece fish for monster aquariums, but it should only be kept with suitably sized tank mates that cannot be swallowed. With proper care, this species can become a hardy and impressive long-term show fish.

Key Features

• Appearance: Long, streamlined body with large reflective silver scales and an elegant surface-swimming posture.
• Size: Offered here at approximately 10 inches, with the potential to grow much larger in the right environment.
• Colors: Bright metallic silver tone that becomes more impressive under clean lighting and good water quality.
• Lifespan: Can live for many years when maintained in a large, stable aquarium with proper diet and filtration.
• Temperament: Predatory and territorial with smaller fish, but generally calm with robust tank mates of similar size.
• Water Type: Freshwater species suited to warm tropical aquariums.

Care Requirements

• Tank Size: A very large tank is essential; for a 10 inch juvenile, start with at least 450 litres, with upgrade plans as the fish grows rapidly.
• Water Parameters: Ideal temperature is 24-30°C with pH around 6.0-7.5 and clean, well-oxygenated water.
• Diet: Feed a varied carnivorous diet including quality floating pellets, sticks, and occasional protein-rich foods appropriate for large predatory fish.
• Tank Mates: Best kept with other large, non-fin-nipping fish such as bigger catfish, large cichlids, or similarly sized monster fish, depending on tank space and temperament.
• Care Level: Better suited for intermediate to advanced aquarists because of its adult size, feeding needs, and requirement for a secure setup.
• Tank Setup: Leave open swimming space at the top, use strong filtration, avoid sharp decor, and always use a tight lid because Arowanas are powerful jumpers.
• Maintenance: Regular water changes are important to control waste buildup, as large predatory fish place a heavy load on the filtration system.

Silver Arowana is not a community fish for small aquariums, but in a properly sized monster tank it becomes a stunning centerpiece with bold personality and elegant movement. Buyers should plan for its future adult size before purchase, as this species thrives best when given room to grow from the start.
