Baby Silver Arowana Care: A Comprehensive Guide for Aquarists
Introduction
The silver arowana (Osteoglossum bicirrhosum) is a majestic and highly sought-after freshwater fish prized for its striking appearance and predatory nature. As a juvenile, the baby silver arowana exhibits unique characteristics and requires specialized care to thrive in captivity. This comprehensive guide will provide aquarists with all the essential information they need to successfully raise and care for baby silver arowanas.
Aquarium Setup
Tank Size:
Baby silver arowanas require a spacious tank to accommodate their rapid growth. A minimum tank size of 100 gallons is recommended for a single juvenile. As they mature, they will need a tank of at least 200 gallons or larger.
Water Parameters:
- Temperature: 75-82°F (24-28°C)
- pH: 6.0-7.5
- Hardness: 5-15 dGH
Filtration:
A powerful filtration system is crucial for maintaining pristine water quality. A combination of mechanical, biological, and chemical filtration is recommended. A canister filter or sump system with a flow rate of at least 10 times the tank volume per hour is ideal.
Substrate:
A dark-colored substrate, such as black sand or gravel, is preferred as it provides a natural contrast to the fish’s silvery scales.
Decorations:
Provide plenty of hiding places for the juvenile arowana, such as driftwood, caves, and live plants. Avoid sharp objects that could injure the fish.
Lighting:
Arowanas prefer dim lighting. Use a combination of natural and artificial light to create a shaded environment.
Feeding
Diet:
Baby silver arowanas are voracious predators and require a diet rich in live food. Offer a variety of live prey, such as:
- Feeder fish (e.g., guppies, tetras)
- Crickets
- Mealworms
- Earthworms
Feeding Frequency:
Feed juveniles multiple times a day, offering small amounts of food each time. As they grow, gradually reduce the feeding frequency to once or twice a day.
Supplements:
Consider supplementing the diet with vitamins and minerals to ensure optimal growth and health.
Health Care
Water Quality:
Regular water changes are essential for maintaining water quality. Perform 20-25% water changes weekly to remove waste and replenish minerals.
Disease Prevention:
Quarantine new fish before introducing them to the main tank to prevent the spread of disease. Monitor the fish closely for any signs of illness, such as lethargy, loss of appetite, or skin lesions.
Treatment:
If disease occurs, consult a qualified veterinarian for proper diagnosis and treatment.
Growth and Development
Growth Rate:
Baby silver arowanas grow rapidly, reaching a length of 6-8 inches within the first year. They can continue to grow up to 4 feet in length as adults.
Coloration:
Juveniles have a silvery body with a faint blue or green sheen. As they mature, their scales develop a more intense metallic sheen.
Behavior:
Baby silver arowanas are generally solitary and territorial. They may exhibit aggressive behavior towards other fish, especially those of similar size or appearance.
Socialization:
While they are not social fish, it is possible to keep multiple silver arowanas in a large tank with ample space and hiding places.
Lifespan:
With proper care, silver arowanas can live for 15-20 years or more.
Special Considerations
Jumping:
Silver arowanas are known for their jumping ability. Ensure the tank has a secure lid to prevent escapes.
Tank Maintenance:
Regular tank maintenance is essential for the well-being of the fish. Clean the substrate, filter, and decorations regularly to remove waste and debris.
Handling:
Avoid handling baby silver arowanas excessively, as they can be easily stressed. Use a soft net and support their body fully when handling.
Conclusion
Raising baby silver arowanas can be a rewarding and challenging experience. By providing proper care and attention to their unique needs, aquarists can successfully nurture these magnificent fish into healthy and thriving adults. Remember to consult with experienced aquarists or professionals for additional guidance and support as needed.
