Silver Arowana (8-10cm) – A Stunning Addition to Your Aquarium

The Silver Arowana (Osteoglossum bicirrhosum) is a captivating freshwater fish prized for its sleek, metallic silver body and graceful swimming style. Native to the Amazon Basin, this prehistoric-looking fish is known for its powerful jumps and unique ability to catch prey from the water’s surface. If you’re looking for an elegant, intelligent, and active predator for your large aquarium, the Silver Arowana is an excellent choice.

Key Features:

• Scientific Name: Osteoglossum bicirrhosum
• Size: 8-10cm (Juvenile)
• Adult Size: Up to 90cm (3 feet)
• Lifespan: 10-15 years (with proper care)
• Temperament: Semi-aggressive
• Diet: Carnivorous

Care Requirements and Tank Setup

Tank Size & Water Conditions:

• Minimum Tank Size: 250-300 gallons (as adults grow large and require ample swimming space)
• Water Temperature: 24-28°C (75-82°F)
• pH Levels: 6.5-7.5
• Water Hardness: 1-8 dGH
• Filtration: Strong and efficient filtration system is required to maintain clean water
• Water Flow: Moderate to strong, mimicking river currents

Tank Setup Tips:

• Use a tight-fitting lid to prevent jumping, as Silver Arowanas are notorious for leaping out of tanks.
• Decorate with driftwood, rocks, and open swimming space to mimic their natural habitat.
• A dimly lit environment with floating plants can help reduce stress and encourage natural behavior.

Tank Mates & Compatibility

Although Silver Arowanas are semi-aggressive, they can co-exist with other large, similarly tempered fish. However, due to their size and predatory nature, smaller tank mates will likely be seen as food.

Best Tank Mates:

✔ Large catfish (e.g., Redtail Catfish, Tiger Shovelnose Catfish)
✔ Peacock Bass
✔ Stingrays
✔ Oscars
✔ Large Plecos
✔ Bichirs

Tank Mates to Avoid:

✖ Small fish (e.g., tetras, guppies) – likely to be eaten
✖ Slow-moving fish (e.g., goldfish) – may get harassed
✖ Aggressive territorial fish (e.g., Flowerhorns) – may lead to fights

Feeding Habits & Diet

The Silver Arowana is a carnivorous predator that requires a protein-rich diet. In the wild, they consume insects, fish, crustaceans, and even small birds.

Recommended Diet:

• Live/Frozen Foods: Feeder fish, crickets, mealworms, shrimp, and bloodworms
• Pellets & Prepared Foods: High-protein carnivorous fish pellets
• Occasional Treats: Beef heart, cut-up seafood (like squid or fish fillets)
• Feeding Frequency: 2-3 times daily for juveniles; once a day for adults

🚫 Avoid: Overfeeding, goldfish (as feeder fish), low-quality or starchy foods

General Care & Maintenance

✔ Perform weekly water changes (20-30%) to keep water parameters stable.
✔ Ensure high oxygenation levels with strong aeration and filtration.
✔ Monitor ammonia and nitrate levels regularly to prevent health issues.
✔ Observe behavior for signs of stress, fin rot, or parasitic infections.
✔ Tank must be well-secured to prevent jumping accidents.

With the right care, a Silver Arowana can become a stunning showpiece in your aquarium, displaying intelligence, agility, and breathtaking beauty. If you're ready for the commitment, this majestic fish will reward you with years of enjoyment!
