7 Times to Avoid Handling Your Arowana

Do you ever find yourself wondering when it is safe to handle your arowana without causing stress or injury? These beautiful fish are sensitive, and knowing the right times to interact with them can keep them healthy and calm.

Arowanas should not be handled during feeding, illness, molting, immediately after moving to a new tank, during breeding, in low oxygen conditions, or when water parameters are unstable. Avoiding contact in these situations reduces stress and prevents potential physical harm to the fish.

Knowing the correct handling times will make caring for your arowana easier and safer, ensuring a calm and thriving environment for your aquatic companion.

During Feeding Time

Arowanas are very focused when they eat, and disturbing them can cause stress or even injury. Handling your fish while it is feeding can lead to missed bites, aggressive behavior, or sudden lunges that might damage their fins. I’ve noticed that even the calmest arowanas become skittish if interrupted during meals. It’s best to let them finish eating completely before attempting any handling or tank maintenance. Consistency in feeding times also helps them stay comfortable in their environment. Avoid reaching into the tank or tapping the glass while they are taking in food. Even a slight disturbance can make them flinch or jump, which can be dangerous if the tank has hard surfaces or decorations. Some arowanas may refuse to eat if they feel threatened, which can affect their health. Providing a calm, undisturbed environment during feeding ensures they get proper nutrition and reduces stress-related behaviors over time.

Handling during feeding can disrupt their eating habits and create stress in the long term.

Arowanas rely on focus during feeding to get enough nutrition. Interruptions can lead to missed meals and aggressive movements. These fish are large and powerful, so any sudden action while they are eating could injure them or damage the tank. I always make sure to wait until my arowana finishes completely before cleaning or reaching in for any reason. Observing them from a distance during this time also helps me gauge their health and appetite, which is critical for their growth and overall well-being. Feeding should be a quiet, undisturbed process.

When They Are Sick

Handling an arowana when it is sick can worsen its condition and delay recovery. Even minimal stress can weaken its immune system further.

Illness makes arowana more sensitive, and unnecessary handling can introduce bacteria or stress. I remember my arowana developing fin rot after a minor scrape caused by early handling. Sick fish need stable, calm conditions and minimal interaction. Only perform essential tasks like water changes or medication under controlled circumstances. Touching or chasing a sick arowana may lead to secondary infections or aggravate existing injuries. It’s important to monitor the fish visually instead, noting changes in behavior, appetite, or swimming patterns. Giving it space while providing optimal water quality, temperature, and nutrition encourages recovery. Avoid sudden movements or loud noises near the tank, as these can create stress responses that interfere with healing. I make sure to wear clean hands and use soft nets only if absolutely necessary. Prioritizing the fish’s comfort and minimizing handling leads to faster, safer recovery, keeping the arowana healthier in the long run.

Immediately After Moving to a New Tank

Arowanas are stressed after a tank change. Handling them right away can increase shock and make them more prone to illness.

The first few hours or even days in a new tank are critical for an arowana to adjust. Water temperature, pH, and oxygen levels can differ slightly, and the fish needs time to acclimate. Any sudden touch or attempt to catch the fish can cause panic, leading to injuries or weakened immunity. I’ve seen my arowana hide in corners or refuse food after moving, showing how sensitive they are to changes. Keeping interaction minimal helps them settle safely.

During this period, it’s important to monitor water conditions and maintain a calm environment. Feeding should be gentle, using minimal movement in the water to avoid startling the fish. Decorations or hiding spots can help reduce stress. Even checking the fish visually should be done without tapping the glass or reaching in unnecessarily. Allowing this adjustment time ensures the arowana adapts smoothly and maintains good health in its new home.

During Breeding Season

Arowanas are highly protective when breeding. Handling during this time can trigger aggression or stress, disrupting spawning behavior.

Breeding arowanas become territorial and defensive. Any interference can cause them to attack, injure themselves, or abandon eggs or fry. I’ve observed my fish change completely during this period, becoming restless and more prone to lunges. Maintaining distance and minimizing tank disturbances is essential to support natural breeding patterns. Stress at this stage can lower fertility or affect the survival of young fish.

Providing a quiet environment with consistent lighting and stable water parameters is crucial. Avoid sudden movements or tapping the tank. Nets or direct handling should be strictly limited to emergencies. Keeping the tank secure from vibrations and external activity helps the fish remain calm. Observing quietly from outside allows you to notice signs of aggression or health issues without disturbing the breeding process. Patience and careful monitoring during this period greatly improve breeding success and the overall well-being of both adult and juvenile arowanas.

During Molting

Arowanas shed their skin and scales occasionally, and handling them can cause tears or stress.

They are very delicate at this time. I’ve noticed my arowana becomes sluggish and avoids movement while molting. Touching it can damage new scales or slow the process.

In Low Oxygen Conditions

Handling arowanas when oxygen levels are low can increase stress and risk of suffocation. They need all energy to breathe properly, so avoid touching or chasing them during these periods.

When Water Parameters Are Unstable

Sudden changes in pH, temperature, or hardness make arowanas sensitive. Handling during these times can cause shock or illness. I always test water first and let the fish adjust before interacting to prevent unnecessary stress.

During Nighttime

Arowanas rest at night and are more vulnerable. Handling during this time disrupts their sleep cycle and increases stress levels.
