Visible injuries, such as torn fins, lesions, or wounds, are a direct sign that your arowana is in pain. Even minor injuries can lead to infections if left untreated.

These injuries may result from aggressive tank mates, sharp decorations, or accidents during feeding. They can also be caused by bacterial or fungal infections that eat away at the skin and fins. Observing how the fish moves and interacts can reveal whether the injury is affecting swimming or feeding. Immediate treatment and isolation can prevent further damage and reduce stress. Proper water maintenance and careful handling are essential to support healing and prevent recurring injuries.

Ignoring visible injuries can escalate problems quickly. Treating wounds promptly with appropriate remedies, maintaining optimal water conditions, and monitoring behavior will improve recovery. Pain from injuries can disrupt normal activity, so attention and care are vital for overall well-being.

Color Changes

Arowanas may show dull or faded colors when they are in pain. Loss of vibrancy can indicate stress, illness, or poor water conditions that affect their overall health.

Rapid or unusual color changes often accompany other symptoms such as clamped fins or lethargy. Monitoring water quality and ensuring proper nutrition helps restore normal coloration.

Lethargy

A lethargic arowana will spend extended periods resting at the bottom or hiding. Reduced activity is a common response to discomfort, pain, or illness. A lack of movement can also indicate energy depletion due to stress or poor feeding. Regular observation of activity levels helps detect problems early. Lethargy often appears alongside loss of appetite and unusual swimming, reinforcing the need for prompt attention. Maintaining a stable, clean environment and providing proper nutrition can improve energy levels and reduce stress. Immediate assessment of water parameters and health status is essential to address the cause effectively.

Abnormal Respiratory Patterns

Labored or rapid gill movement can indicate that your arowana is experiencing discomfort or stress. Watching how it breathes helps identify early signs of illness or poor water conditions.
