Feeding Habits and Nutrition for Arowana Fish

Arowana fish, known for their stunning appearance and graceful swimming style, require proper feeding habits and a well-balanced diet to thrive in captivity. Whether you are a beginner or an experienced fish keeper, understanding the feeding habits and nutritional requirements of Arowanas is crucial for their health and longevity. In this article, we will explore the key aspects of feeding habits and nutrition for Arowana fish, providing you with valuable insights to ensure the well-being of your aquatic companions.

Feeding Habits of Arowana Fish

Arowanas are primarily carnivorous fish, known for their voracious appetite and predatory nature. Observing their natural feeding habits in the wild can give us valuable clues about their nutritional needs. Here are some important points to consider:

  • Jumping Predators: Arowanas are renowned for their exceptional jumping ability, which they use to catch prey located above the water’s surface. In the wild, they leap out of the water to capture insects, small birds, and other creatures that venture too close. This behavior is a result of their natural instinct and is often exhibited in captivity as well.
  • Ambush Predators: Arowanas are ambush predators, patiently waiting for the right moment to strike. They have a keen eye for movement and will quickly react to potential prey. Their long, slender bodies and sharp teeth make them efficient hunters.
  • Diurnal Feeders: Arowanas are diurnal, meaning they are most active and feed during daylight hours. This behavior is linked to their natural habitat, where they rely on sunlight to spot prey near the water’s surface. It’s important to provide them with regular feeding times during the day to align with their natural feeding patterns.
  • Surface-Oriented Feeders: Arowanas spend a significant amount of time near the water’s surface. They have adapted to become surface-oriented feeders, often rising to the top to catch their prey. This behavior should be taken into consideration when designing the tank setup, providing ample surface area for them to swim and feed comfortably.
  • Selective Feeders: Arowanas can be picky eaters, especially when it comes to accepting prepared or frozen foods. They tend to show a preference for live food due to the movement and sensory stimulation it provides. However, with patience and persistence, they can be trained to accept a variety of high-quality commercial foods.
  • Opportunistic Feeders: Arowanas are opportunistic feeders, meaning they will take advantage of any food source that presents itself. This can include insects that fall into the water, small fish that swim near the surface, or even bits of food that are introduced into their environment. Their voracious appetite and ability to adapt to different food sources contribute to their survival in the wild.

Understanding the unique feeding habits of Arowana fish is crucial for replicating their natural feeding behaviors in captivity. By providing appropriate live foods, mimicking their hunting instincts, and offering a diverse diet, you can ensure that your Arowanas remain healthy, active, and satisfied.

Nutritional Requirements of Arowana Fish

To maintain optimal health and vibrant colors, Arowana fish require a well-balanced diet that meets their nutritional requirements. Here are the key nutrients to consider:

Nutrient Function Sources
Protein Essential for growth, tissue repair, and overall development. Fish-based protein sources, such as small fish, insects, shrimp, and high-quality pellets.
Fats Provide energy, support bodily functions, and enhance coloration. Fish oil, shrimp, and other sources of healthy fats.
Vitamins Contribute to overall health and immune function. Vitamin-enriched pellets, fresh vegetables, and occasional supplementation (if necessary).
Minerals Important for bone development, growth, and overall health. Calcium-rich foods (such as small bones), phosphorus-rich foods, and mineral-enriched pellets.

It’s important to note that while live foods like small fish, insects, and shrimp can form a significant part of their diet, it’s essential to supplement with other options such as high-quality pellets, frozen foods, and occasionally fresh vegetables to ensure a well-rounded diet.

By providing a variety of nutrient-rich foods, you can ensure that your Arowana fish receive the necessary proteins, fats, vitamins, and minerals they need to thrive.

Remember to consult with aquatic specialists or experienced fishkeepers for specific recommendations tailored to the species of Arowana you have, as different varieties may have slightly different dietary requirements.

Feeding Tips for Arowana Fish

Consider the following tips to ensure the best feeding practices for your Arowana fish:

  1. Feed a variety of live foods: Arowanas have a strong preference for live foods. Offer them a variety of options such as small fish, insects, shrimp, and earthworms. This not only provides essential nutrients but also stimulates their natural feeding instincts.
  2. Prey size: Consider the size of the prey you offer to your Arowana. It should be appropriate for the size of your fish. Avoid offering prey that is too large for them to consume comfortably, as it can cause digestive issues.
  3. Rotate live food sources: To maintain a diverse diet, rotate the types of live food you offer. This ensures that your Arowana receives a wide range of nutrients and prevents them from becoming overly dependent on a single food source.
  4. Frozen foods: Frozen foods are a convenient alternative to live foods and can provide similar nutritional benefits. Look for frozen options like bloodworms, brine shrimp, and krill. Thaw them properly before offering them to your fish.
  5. High-quality pellets: Choose high-quality pellets specifically formulated for Arowanas. Look for pellets that contain a good balance of protein, fats, vitamins, and minerals. Soak the pellets briefly in tank water before feeding to make them easier to digest.
  6. Occasional fresh vegetables: While Arowanas are primarily carnivorous, they can benefit from occasional supplementation with fresh vegetables. Blanched peas, spinach, or lettuce can be offered as a source of fiber and additional nutrients.
  7. Avoid overfeeding: Overfeeding can lead to obesity and health problems in Arowanas. Feed them an amount they can consume within a few minutes, and remove any uneaten food from the tank to maintain water quality.
  8. Consider feeding frequency: Arowanas benefit from frequent feedings due to their high metabolic rate. Split their daily food portions into two to three feedings spread throughout the day. This ensures they receive a steady supply of nutrients.
  9. Water quality and feeding: Good water quality is crucial for the health of your Arowanas. Avoid feeding them in a tank with poor water conditions, as it can lead to stress and disease. Perform regular water changes and monitor water parameters closely.
  10. Observe feeding behavior: Take time to observe your Arowanas while they are feeding. This allows you to ensure that all fish are getting their fair share of food and identify any potential issues with their appetite or feeding behavior.

Remember, each Arowana is unique, and it may take time to find the ideal feeding routine and diet that suits your fish. By following these feeding tips and providing a varied and nutritious diet, you can promote the health, growth, and vibrant colors of your Arowana fish.


Understanding the feeding habits and nutritional requirements of Arowana fish is essential for their overall health and well-being. By providing a balanced diet that includes a variety of live foods, pellets, and supplements, you can ensure your Arowanas thrive in captivity. Remember to monitor their feeding habits, adjust their diet as needed, and create an environment that promotes their natural feeding behaviors. With proper nutrition and care, your Arowanas will reward you with their stunning beauty and graceful presence.
