Silver Arowana Care

Silver Arowanas require a large, secure aquarium with excellent filtration and plenty of unobstructed swimming space. They are powerful jumpers, so a tight-fitting aquarium lid is essential.

Because Silver Arowanas grow large, plan for their adult size before purchasing. A juvenile may look small initially but can grow rapidly with proper nutrition and water quality.

Maintain stable water conditions and perform regular water changes to keep the aquarium clean and healthy.

Recommended Water Parameters

• Temperature: 75–82°F
• pH: 6.0–7.5
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Nitrate: Keep low with regular water changes
• Water Flow: Moderate
• Filtration: Heavy-duty filtration recommended

Feeding

Silver Arowanas are carnivorous surface feeders and should receive a varied, high-quality diet appropriate for their size.

Recommended foods include:

• High-quality carnivorous pellets
• Insects
• Shrimp
• Krill
• Earthworms
• Fish-based frozen foods
• Other appropriately sized aquatic foods

Avoid feeding unquarantined feeder fish whenever possible because of the risk of introducing parasites and disease.

Feed appropriately sized portions and avoid overfeeding, especially with rapidly growing juveniles.

Silver Arowana Tank Mates

Silver Arowanas can be territorial and predatory, particularly as they grow. Tank mates must be selected carefully and should be large enough that they cannot easily be swallowed.

Potential tank mates in sufficiently large systems may include:

• Large Plecos
• Large freshwater stingrays
• Large peaceful South American cichlids
• Large catfish
• Other appropriately sized large freshwater species

Compatibility depends on the individual fish, aquarium size, and available territory. Avoid small fish and aggressive species that may injure the Arowana.

Aquarium Setup

Silver Arowanas require a very large aquarium or custom-built aquatic system as they mature.

Recommended setup features include:

• Large open swimming area
• Strong filtration
• Powerful biological filtration
• Secure aquarium lid
• Smooth decorations
• Driftwood
• Dim or moderate lighting
• Minimal sharp objects
• Excellent oxygenation
• Regular water changes

Avoid sharp rocks and decorations that could injure the Arowana while swimming or jumping.

Important: Plan for Adult Size

Silver Arowanas are not suitable for small aquariums. They can reach approximately 3 feet in length, making a very large aquarium necessary for long-term care.

This is an advanced fish for aquarists who are prepared to provide substantial aquarium space, filtration, food, and long-term care.
