Arowana fish, often referred to as “dragon fish,” are among the most sought-after aquarium fish due to their majestic appearance and cultural significance. They are considered a symbol of good luck, prosperity, and strength, particularly in Asian cultures. However, caring for an Arowana requires dedication, knowledge, and proper maintenance to ensure their health and longevity. This guide provides detailed insights into arowana fish for sale care, covering tank setup, diet, water conditions, and common health issues.
Choosing the Right Tank
Arowanas are large fish that require spacious tanks to thrive. The minimum tank size for a juvenile Arowana should be at least 75 gallons, while adults need a tank of 150-250 gallons or more, depending on the species. Arowanas are powerful swimmers and need a long and wide tank to accommodate their movement. Ensure the tank has a sturdy, secure lid since Arowanas are known for their ability to jump.
Water Conditions and Filtration
Maintaining optimal water parameters is crucial for Arowana health. The ideal water conditions include:
- Temperature: 75-86°F (24-30°C)
- pH Level: 6.5-7.5
- Water Hardness: Soft to moderately hard (1-8 dGH)
- Ammonia & Nitrite Levels: Should always be at 0 ppm
Arowanas require strong filtration systems to keep the water clean and well-oxygenated. Canister filters and sump systems work best to maintain high water quality. Regular water changes (25-30% weekly) help prevent the buildup of harmful toxins.
Feeding and Nutrition
Arowanas are carnivorous and thrive on a protein-rich diet. A well-balanced diet includes:
- Live and Frozen Foods: Crickets, mealworms, shrimp, and small fish
- Pellets: High-quality Arowana-specific pellets for balanced nutrition
- Occasional Treats: Earthworms, frogs, and feeder fish (sparingly, to prevent disease transmission)
Avoid overfeeding, as Arowanas are prone to obesity and digestive issues. Feed juveniles twice a day and adults once a day, adjusting portions based on their size and activity level.
Tankmates and Compatibility
Arowanas are territorial and aggressive, so choosing compatible tankmates is essential. Suitable companions include:
- Large Catfish (Arowana-friendly species like Plecos or Redtail Catfish)
- Bichirs
- Oscars
- Silver Dollars
- Peacock Bass
Avoid keeping them with smaller or slow-moving fish that they might see as prey. Housing multiple Arowanas together is risky unless done in a very large tank with careful monitoring.
Common Health Issues
Arowanas are susceptible to several health problems, including:
- Drop Eye Syndrome: Common in Silver Arowanas, often due to poor diet or excessive bottom-feeding behavior.
- Fin Rot: Caused by bacterial infections from poor water conditions.
- Parasitic Infections: External parasites like ich can develop due to stress or unclean water.
- Swim Bladder Disease: Leads to difficulty swimming, often resulting from improper diet or water conditions.
Preventative care includes maintaining optimal water quality, providing a varied diet, and observing your Arowana for any behavioral changes or signs of illness.
Handling and Interaction
Arowanas are intelligent fish that recognize their owners. While they are not ideal for direct handling, they can be trained to take food from your hand. Avoid unnecessary handling, as it can cause stress and injury.
Breeding Arowanas
Breeding Arowanas in home aquariums is challenging due to their size and specific breeding requirements. They are mouthbrooders, meaning males carry the fertilized eggs in their mouths until they hatch. Successfully breeding them typically requires large outdoor ponds and controlled environmental conditions.
Conclusion
Caring for an Arowana requires commitment, but the rewards of owning such a magnificent fish are well worth the effort. By providing the right tank conditions, balanced nutrition, and proper health care, you can ensure your Arowana lives a long and healthy life. With patience and dedication, your Arowana will not only thrive but also become a captivating centerpiece in your aquarium.
