Care Tips for Arowanas

Arowanas are unique and beautiful fish, but they require special care to thrive. Here are some essential tips for maintaining a healthy environment for your Arowanas.Mastering Arowana Care

Tank Size

Arowanas are large, active fish that need plenty of space to swim. The minimum tank size for most species is 250 gallons. Ensure your tank is long and wide to accommodate their swimming habits.


A varied diet is crucial for Arowanas. They are carnivorous and thrive on a mix of:

  • Live food: insects, small fish, and crustaceans.
  • Frozen food: bloodworms, shrimp, and krill.
  • Pellets: high-quality Arowana pellets to ensure they get all the necessary nutrients.

Water Parameters

Maintaining the correct water parameters is vital for the health of your Arowana:

  • Temperature: Keep the water between 75-82°F (some species may require slightly higher temperatures).
  • pH: Maintain a pH level between 6.0-7.5, depending on the species.
  • Filtration: Use a powerful filtration system to keep the water clean and oxygenated. Arowanas produce a lot of waste, so a robust filter is essential.

Tank Setup

  • Decorations: Provide ample hiding spots and open swimming areas. Avoid sharp decorations that could injure your Arowana.
  • Lighting: Use moderate lighting. Too much light can stress the fish, while too little can affect their coloration.
  • Tank Lid: Arowanas are known to jump, so a secure tank lid is necessary to prevent accidents.

Behavior and Compatibility

Arowanas are territorial and can be aggressive, especially towards smaller fish. It’s best to keep them alone or with other large, non-aggressive fish. Monitor their behavior and be prepared to separate them if necessary.

Regular Maintenance

  • Perform regular water changes (about 20-30% weekly) to keep the water quality high.
  • Test the water parameters regularly to ensure they remain within the optimal range.
  • Clean the tank and decorations to prevent the buildup of harmful bacteria and algae.

Health Monitoring

Keep an eye on your Arowana for signs of illness, such as changes in appetite, coloration, or behavior. Common issues include:

  • Parasites: Look for visible signs like spots or worms.
  • Infections: Cloudy eyes, fin rot, or unusual swimming patterns can indicate bacterial or fungal infections.
  • Nutritional Deficiencies: Ensure a balanced diet to prevent issues like deformities or weakened immune systems.

By following these care tips, you can create a thriving environment for your Arowana, ensuring they live a long and healthy life.
