7 Unusual Arowana Behaviors Explained

Arowanas are striking fish that captivate many aquarists with their elegance and size. Observing them closely can reveal behaviors that seem unusual or even puzzling at first glance, showing there is more beneath their calm exterior.

Unusual behaviors in arowanas, such as surface jumping, tail chasing, or head-down hovering, are often linked to environmental factors, stress, feeding patterns, and natural instincts. Understanding these actions helps maintain proper care and ensures fish welfare.

These behaviors may appear odd, yet each action reflects an essential aspect of your arowana’s health and habitat, offering insight into its natural tendencies and daily life.

Surface Jumping

Many arowanas are known to leap out of the water, which can be alarming. This behavior often happens when the fish is startled, stressed, or trying to catch prey. Tank conditions play a major role; insufficient space, low oxygen, or abrupt movements nearby can trigger jumps. Lighting and reflections may also confuse the fish, causing sudden bursts toward the surface. Young arowanas tend to jump more as they explore their surroundings and develop coordination. While this is a natural instinct, repeated jumping can lead to injuries or escape from the tank. To minimize this behavior, aquarists often cover tanks securely and ensure stable water conditions. Proper feeding schedules and minimizing disturbances also reduce the likelihood of sudden leaps. Recognizing the triggers behind surface jumping helps in creating a safer environment that supports the fish’s health and natural behavior. Observation and gradual adjustments are key to managing this common activity.

Jumping can be controlled through careful tank management and understanding of environmental triggers affecting the fish’s instincts.

Providing a covered tank, consistent feeding, and gentle handling are effective methods to reduce jumping. Adjusting lighting and adding floating plants can also calm arowanas. Regular monitoring ensures stress factors are identified quickly. Over time, fish adapt to secure surroundings, reducing the risk of injury. Encouraging natural swimming and avoiding sudden disturbances promotes a calmer, more predictable behavior.

Tail Chasing

Tail chasing is often noticed in arowanas that spend time circling or biting their own tails.

This behavior can indicate boredom, insufficient stimulation, or underlying stress. In smaller tanks, fish may lack space for natural movement, leading to repetitive circling. Nutritional deficiencies or irregular feeding routines also contribute to tail-chasing. In some cases, minor injuries or irritation can provoke the fish to focus on its tail. Observation of water quality, temperature, and tank enrichment is important to identify the cause. Adding hiding spots, appropriate companions, or gentle water currents can redirect energy and encourage healthier behavior. Ensuring a balanced diet with high-quality pellets or live foods addresses nutritional needs that may trigger repetitive actions. Tail-chasing can be harmful if persistent, causing injury or scale damage. Understanding why arowanas chase their tails allows for corrective measures that protect health, reduce stress, and support a more natural daily routine in captivity.

Head-Down Hovering

Head-down hovering often signals discomfort or stress in arowanas. Poor water quality, incorrect temperature, or low oxygen levels can cause this posture. It may also appear after aggressive interactions or sudden changes in the tank environment, reflecting an instinctive response to perceived threats.

Fish may hover head-down to reduce energy expenditure while maintaining awareness of surroundings. It can indicate internal issues like swim bladder problems or minor infections. Tank placement, water flow, and hiding spots influence this behavior. Consistent observation and water testing help detect problems early. Adjusting environmental conditions often restores normal swimming posture, reducing stress.

Maintaining optimal tank conditions, including stable temperature, clean water, and adequate oxygen, minimizes head-down hovering. Balanced nutrition and reducing sudden disturbances contribute to healthier, more confident swimming. Regularly monitoring behavior ensures issues are addressed promptly, improving overall well-being and stability in the aquatic environment.

Aggressive Fin-Flaring

Fin-flaring is a common display of territoriality and dominance among arowanas, signaling warning or readiness to defend space.

This behavior becomes noticeable when new fish are introduced or when tanks are overcrowded. Arowanas flare fins to appear larger and more intimidating, establishing hierarchy without direct combat. It can also occur during feeding when competition arises, or if reflections in the tank mirror their image, triggering defensive instincts. Observing frequency and context of fin-flaring helps determine whether it is a natural display or stress-related. Tank size, decorations, and hiding spots influence how often arowanas exhibit this behavior.

While generally harmless, prolonged fin-flaring may indicate environmental stress or lack of enrichment. Providing sufficient space, visual barriers, and consistent routines can reduce excessive aggression. Monitoring interactions with tank mates ensures compatibility, preventing injury and stress. Adjusting lighting, minimizing reflections, and maintaining balanced feeding schedules supports calmer behavior, allowing fish to exhibit natural dominance gestures without harm. Consistent care reinforces stability, improving overall health and comfort in the aquatic habitat.

Glass Surfing

Glass surfing occurs when arowanas swim repeatedly along the tank walls, often appearing restless. This behavior can signal boredom, stress, or the desire for a larger space, as the fish reacts to limited room or visual stimuli.

Frequent glass surfing may also indicate water quality issues or improper tank setup. Monitoring movement patterns and environmental factors can help determine the cause and prevent injuries.

Gulping Air

Arowanas sometimes rise to the surface to gulp air, which is a natural behavior for certain species. This action supplements oxygen intake, especially in tanks with lower oxygen levels. Observing how often this occurs provides insight into water conditions and fish health.

Shadow Chasing

Arowanas may follow shadows or reflections, interpreting them as potential prey or rivals. This behavior is instinctive and often appears when lighting or objects create moving shapes in the tank.

Belly-Up Floating

Occasionally, arowanas float belly-up near the surface, which can be a sign of stress, swim bladder issues, or water problems. Immediate checks on water parameters and gentle handling are necessary to address underlying causes.
