Arowana Habitat and Care

Ideal Tank Setup

Tank Size: Arowanas require spacious tanks to thrive, with a minimum recommended size of 150 gallons for juveniles and up to several hundred gallons for adult specimens, considering their large size and active nature.
Water Parameters: Maintain stable water parameters within the tank, including a temperature range of 75-82°F (24-28°C), pH level between 6.5 and 7.5, and water hardness of 5-15 dGH.
Filtration: Invest in a robust filtration system capable of handling the bio-load produced by Arowanas, as they are messy eaters and can generate significant waste. Consider using both mechanical and biological filtration to ensure optimal water quality.
Lighting: Provide subdued lighting within the tank to mimic the dimly lit conditions of their natural habitat. Avoid excessive lighting, as it can cause stress to the fish.

Water Quality Maintenance Tips

Perform regular water changes to remove accumulated waste and maintain pristine water quality. Aim for weekly water changes of 20-30% to prevent the buildup of harmful substances.
Monitor water parameters using reliable test kits and adjust as necessary to keep them within the recommended ranges.
Avoid overfeeding, as uneaten food can decompose and compromise water quality. Feed Arowanas sparingly, offering a varied diet consisting of high-quality pellets, live or frozen foods, and occasional treats like insects or small fish.

Suitable Tank Mates and Compatibility Considerations

Arowanas are predatory fish and may view smaller tank mates as potential prey. Therefore, choose tank mates carefully, opting for species that are compatible in size and temperament.
Large, peaceful fish such as Oscars, large catfish, and other similarly sized cichlids can make suitable tank mates for Arowanas, provided there is ample space and hiding spots to reduce aggression.
Avoid keeping Arowanas with smaller or more timid species that may become stressed or intimidated by their presence, as this can lead to territorial disputes and aggression.

By creating a suitable habitat and providing proper care for Arowanas, aquarists can ensure the health and well-being of these magnificent fish, allowing them to thrive and flourish in captivity.

Feeding Habits and Nutrition

Dietary Requirements

Arowanas are carnivorous fish with a diverse diet that includes live, frozen, and prepared foods.
Offer a variety of foods to meet their nutritional needs, including live or frozen options such as small fish, shrimp, crickets, and earthworms, as well as high-quality pellets or sticks specifically formulated for predatory fish.

Feeding Schedule and Portion Control

Establish a consistent feeding schedule to maintain optimal health and prevent overfeeding. Feed adult Arowanas once or twice daily, providing only what they can consume within a few minutes.
Monitor portion sizes closely, as Arowanas have voracious appetites and can easily become overweight if fed excessively. Adjust feeding amounts based on the fish’s size and activity level.

Common Feeding Issues and How to Address Them

Refusal to Eat: Some Arowanas may exhibit reluctance to eat when first introduced to a new environment or if they are stressed. Ensure water quality is optimal, and try offering a variety of enticing foods to stimulate their appetite.
Finicky Eating Habits: Arowanas may develop preferences for certain types of food or feeding methods. Experiment with different food options and feeding techniques to find what works best for your fish.
Aggressive Feeding Behavior: Arowanas are known for their aggressive feeding behavior and may become territorial during feeding time. To prevent conflicts, consider feeding them separately from other tank mates or using feeding rings to control their movements.

By understanding the dietary requirements and feeding habits of Arowanas, aquarists can provide a balanced and nutritious diet that supports their health and vitality in the aquarium environment. Regular monitoring and adjustment of feeding practices can help address common issues and ensure the well-being of these magnificent fish.

Health and Disease Management

Common Health Issues in Arowana

Arowanas are generally hardy fish, but they can still be susceptible to various health issues, including fungal, bacterial, and parasitic infections.
Stress-related illnesses, such as fin rot, ich, and dropsy, can also occur, especially if water quality is poor or environmental conditions are unfavorable.

Symptoms of Diseases and Preventive Measures

Keep a close eye on your Arowanas for any signs of illness, including changes in behavior, appetite, or appearance.
Symptoms of diseases may include abnormal swimming patterns, lethargy, loss of appetite, visible lesions or discoloration, and rapid breathing.
To prevent diseases, maintain optimal water quality through regular water changes, proper filtration, and avoiding overstocking. Quarantine new fish before introducing them to the main tank to prevent the spread of pathogens.

Treatment Options and When to Consult a Veterinarian

If you notice any signs of illness in your Arowanas, promptly isolate the affected fish in a quarantine tank to prevent the spread of disease.
Treatments for common Arowana diseases may include medicated baths, antibiotic or antifungal medications, and salt baths to help alleviate symptoms and eradicate pathogens.
If the condition persists or worsens despite treatment, or if you’re unsure about the appropriate course of action, consult a qualified aquatic veterinarian for professional advice and assistance.

By staying vigilant and proactive in monitoring the health of your Arowanas, implementing preventive measures, and seeking timely treatment when necessary, you can help ensure the well-being and longevity of these magnificent fish in your aquarium.
