1. Understanding the Asian Arowana

The Asian Arowana (Scleropages formosus) is native to Southeast Asia and is known for its elongated body, large fins, and metallic sheen. They can grow up to 36 inches in length and live for several decades in the right conditions. Their majestic appearance and impressive size make them a centerpiece in any aquarium, but they also come with unique care requirements.

The Asian Arowana (Scleropages formosus) is known for its impressive size and distinct appearance. Here’s a detailed overview of the asian arowana size aspects of this remarkable fish:

**Adult Size

• Maximum Length: Asian Arowanas can reach up to 36 inches (90 cm) in length when fully grown. In captivity, they typically grow to about 24-30 inches (60-75 cm), depending on tank size, diet, and care.
• Growth Rate: These fish grow relatively quickly during their early years. In optimal conditions, they can grow several inches a year. However, growth may slow down as they approach their full size.

**Juvenile Size

• Initial Size: Juvenile Asian Arowanas are usually sold at sizes ranging from 4 to 8 inches (10-20 cm). They are often kept in smaller tanks initially but will need larger accommodations as they grow.
• Growth Expectations: It’s important to provide adequate space and proper care during their juvenile stage to support healthy growth. Regular monitoring and adjustment of tank conditions will help them reach their full size.

2. Setting Up the Perfect Tank

Tank Size: Given their large size, Asian Arowanas require a spacious tank. You need a minimum of 250 gallons tank for a single adult Arowana. Larger tanks are preferable as they allow the fish to swim freely and reduce stress.

Tank Type: Choose a long, wide tank rather than a tall one. Arowanas are surface-swimmers and need ample horizontal space to move comfortably.

Substrate and Decorations: Choose a smooth substrate to prevent injuries. Avoid sharp decorations and ensure any tank ornaments are securely placed. Provide hiding spots and open swimming areas to mimic their natural habitat.

Filtration: Install a high-quality filtration system into your tank to maintain excellent water quality. Arowanas produce a lot of waste, so a powerful filter is essential to keep the tank clean and the water parameters stable.

3. Maintaining Water Quality

Water Temperature: Try to maintain the water temperature of your tank between 75-82°F (24-28°C). Arowanas are sensitive to temperature fluctuations, so use a reliable heater and monitor the temperature regularly.

pH Level: Aim for a pH range of 6.5-7.5. Regularly test your tank water and make adjustments as necessary to keep the pH level stable.

Water Changes: Perform regular water changes—at least 20-30% of the tank volume weekly. This helps keep the water clean and free of harmful substances.

Water Conditioners: Use water conditioners to remove harmful chemicals like chlorine and chloramine from tap water before adding it to the tank.

4. Feeding Your Asian Arowana

Diet: Asian Arowanas are carnivorous and require a varied diet. Feed them a mix of high-quality pellets, live or frozen food like shrimp, fish, and insects. They also benefit from occasional treats like earthworms or small fish.

Feeding Schedule: Feed your Arowana 2-3 times a week. Don’t make the mistake of overfeeding as it can lead to obesity and water quality issues.

Feeding Tips: Observe your fish’s eating habits and adjust the diet based on their preferences and nutritional needs. Ensure that food is appropriately sized for their mouth.

5. Monitoring Health and Behavior

Health Checks: Regularly inspect your Arowana for signs of illness such as unusual swimming patterns, loss of appetite, or physical abnormalities. Early detection of your fish health issues can prevent more serious problems.

Behavioral Signs: Healthy Arowanas are active and curious. If you notice lethargy, erratic swimming, or hiding, it could be a sign of stress or illness.

Common Issues: Watch out for common issues like skin infections, fin rot, and internal parasites. Consult with an aquatic veterinarian if you observe any symptoms.

6. Socialization and Tank Mates

Tank Mates: Asian Arowanas can be aggressive and territorial. Choose tank mates carefully to avoid conflicts. Compatible tank mates include larger, non-aggressive fish such as arapaima or pacus. For the right tank mates, use fishelly’s tank buddy service.

Socialization: While Arowanas can be solitary, they may tolerate certain species if introduced properly. Ensure that tank mates are of similar size to prevent bullying.

7. Breeding Asian Arowanas

Breeding Asian Arowanas in captivity is challenging and requires specific conditions. It’s generally recommended to seek expert advice and prepare for a complex breeding process involving precise water conditions and proper tank setup.

8. Legal and Ethical Considerations

Legal Requirements: In some regions, owning an Asian Arowana may require special permits due to their status as a protected species. Check local regulations and ensure compliance with all legal requirements.

Ethical Care: Providing optimal care for your Arowana is not only beneficial for the fish but also reflects responsible fishkeeping practices. Make sure your fish has a suitable environment and receives proper attention.
