Why Is My Arowana Resting on the Bottom All Day?

Your arowana may seem calm and graceful, gliding through the water. Lately, you might have noticed it spending most of its time at the bottom of the tank, resting quietly instead of swimming around.

Arowanas resting at the bottom of the tank all day is often due to stress, poor water conditions, or illness. Temperature fluctuations, low oxygen levels, and inadequate tank setup can also cause this unusual behavior in these fish.

Observing your fish closely can reveal subtle signs of discomfort or imbalance in its environment. Small adjustments may make a significant difference in your arowana’s health and daily activity levels.

Common Reasons Your Arowana Rests at the Bottom

Arowanas often stay near the bottom when they feel unwell or uncomfortable. Water quality is the most common reason. High ammonia or nitrite levels can make fish lethargic. Temperature is another factor; arowanas prefer stable, warm water. Sudden changes in temperature or pH can cause them to rest more than usual. Stress from overcrowding or aggressive tankmates can also make them seek the bottom as a safe space. Diet plays a role too. Overfeeding or poor nutrition can reduce energy levels. Sometimes, resting at the bottom is natural if your fish is digesting food, but prolonged inactivity should be monitored. Lighting and tank setup also influence behavior. Dim or improper lighting can make arowanas less active. Observing their movement patterns over time helps determine whether the behavior is temporary or a sign of a bigger issue. Consistent monitoring and care can prevent long-term problems.

Water issues and stress are often linked to bottom-dwelling behavior in arowanas, making regular tank maintenance essential for their activity.

It’s helpful to check water parameters weekly. Ammonia, nitrite, nitrate, and pH levels should remain in safe ranges. Temperature should be stable between 75-82°F, with minimal fluctuations. Remove uneaten food promptly to prevent decay and harmful bacterial growth. Consider whether tankmates are causing stress, and provide hiding spaces if needed. Feeding high-quality, balanced food supports energy and reduces lethargy. Observing your arowana during feeding can reveal whether it’s alert and responsive. Lighting schedules should mimic natural day and night cycles, allowing the fish to rest and be active appropriately. Tank size matters; arowanas need plenty of swimming space. Long-term neglect of these factors can weaken their immune system, increasing vulnerability to illness. By addressing these environmental and dietary needs, your arowana can regain normal activity levels and enjoy a healthier, more engaging habitat.

Monitoring Health and Behavior

Keep an eye on changes in movement, appetite, or coloration, as they indicate health issues.

Sudden lethargy or bottom-dwelling can signal internal problems such as infections, parasites, or organ stress. Behavioral changes often appear before visible symptoms.
