The Ultimate Guide for Raising an Arowana as a Pet
Choosing the Right Tank Size and Setup
Arowanas are large, active fish that require ample space to thrive. For a single adult arowana, a minimum tank size of 240 gallons (908 liters) is recommended. However, larger tanks are always preferable, especially if you plan to keep multiple arowanas or other species. The tank should be at least 6 feet long to accommodate their swimming patterns.
Ensure the tank has a strong filtration system capable of handling the volume of water and maintaining water quality. Additionally, incorporate robust decorations such as driftwood, rocks, and plants to create hiding spots and enrich the environment. A secure lid is essential due to the arowana’s tendency to leap out of the water.
Water Quality Maintenance
Maintaining optimal water quality is crucial for arowanas’ health. Regular partial water changes (about 20% weekly) help control ammonia, nitrite, and nitrate levels. Use a high-quality aquarium filter and ensure it is appropriately sized for the tank volume. Monitor water parameters closely, aiming for a pH between 6.5 and 7.5 and a temperature range of 78-82°F (25.5-27.8°C).
Install a protein skimmer if you have saltwater arowanas, and consider adding live plants to naturally improve water quality. Regular testing of water parameters ensures a stable environment conducive to your arowana’s well-being.
Ideal Temperature and pH Levels
Arowanas prefer temperatures ranging from 78 to 82°F (25.5 to 27.8°C). Maintain a consistent temperature by using a reliable heater and thermometer. Fluctuations can stress the fish, leading to health problems.
The ideal pH range for arowanas is between 6.5 and 7.5. Soft, slightly acidic water conditions are best. Regularly test the pH level and adjust it as necessary using appropriate aquarium chemicals or by changing the substrate type.
Diet and Feeding Habits
Arowanas are carnivorous and require a varied diet rich in proteins. Feed them a mix of live foods like feeder fish, earthworms, and crickets, as well as frozen foods such as bloodworms, prawns, and krill. Avoid overfeeding; feed only what they can consume within a few minutes. Offer meals twice daily, ensuring proper nutrition while preventing obesity.
Varying the diet prevents nutritional deficiencies and keeps your arowana healthy. Supplement their diet with vitamin-enriched food occasionally to enhance their overall health.
Common Health Issues and Preventive Measures
Common health issues include bacterial infections, fungal infections, and parasites. Symptoms may include lethargy, loss of appetite, abnormal swimming behavior, and visible lesions or growths. To prevent these issues, maintain excellent water quality, quarantine new additions to the tank, and observe your arowana regularly for any signs of distress.
If you notice any health issues, consult a veterinarian specializing in exotic fish. Early intervention can prevent more severe complications. Regular health checks and treatments as needed will ensure your arowana remains healthy.
Suitable Tank Mates
Select tank mates carefully, considering the aggressive nature of arowanas. Compatible species include large, peaceful fish like oscars, pacus, and some catfish varieties. Avoid small or slow-moving fish, as they may become prey. Ensure all tank mates are of similar size to prevent bullying or dominance issues.
Always introduce new fish gradually and monitor interactions closely. Compatibility depends on individual temperaments, so adapt your choices based on observations.
Tips for Handling and Bonding with Your Arowana
Handle your arowana minimally and gently, using a net or a container. Excessive handling can stress the fish, leading to health problems. When feeding, position yourself consistently at one side of the tank to encourage interaction. Over time, your arowana may recognize you and respond positively to your presence.
Bonding requires patience and consistency. Spend time near the tank daily, speaking softly or playing gentle music. This helps create a positive association with your presence. Remember, each arowana is unique, so tailor your approach based on their responses.
