Their diet should consist of a mix of protein sources, such as insects, fish, and crustaceans, along with some plant-based foods to ensure a well-rounded diet. Arowanas require vitamins and minerals, such as calcium, phosphorus, and vitamin D, for strong bones and proper growth.

What types of food can I feed my Arowana?

Arowanas can eat a variety of food items, including:


Live or dried insects like mealworms, superworms, crickets, and other feeder insects.


Small live or frozen fish, such as guppies, goldfish, or feeder fish, are suitable for Arowanas.


Shrimp, krill, and other crustaceans can provide essential nutrients for your Arowana.


High-quality pellets specially formulated for Arowanas can offer a balanced and convenient diet.

Plant-based foods:

While Arowanas are primarily carnivorous, they can benefit from occasional plant-based foods, such as peas or lettuce, to support their overall health.

How do I ensure my Arowana receives a balanced diet?

To provide your Arowana with a balanced diet, it's essential to offer a variety of food sources. This helps ensure they receive the necessary nutrients to support their growth, development, and overall health.

Additionally, using vitamin and mineral supplements can help fill any nutritional gaps in your Arowana's diet.

Can I feed my Arowana only pellets or live food?

While it's possible to feed your Arowana only pellets or live food, it's not recommended, as this can lead to an imbalanced diet and potential nutritional deficiencies.

Arowana Feeding FAQs

How often should I feed my Arowana?

The feeding frequency for Arowanas depends on their age and size. Juvenile Arowanas require more frequent feedings, typically 2-3 times per day, to support their rapid growth. As they mature, you can gradually reduce the feeding frequency to once or twice a day. Adult Arowanas can be fed once a day or even every other day, depending on their size and activity level.

How much food should I give my Arowana per feeding?

The amount of food to give your Arowana per feeding will vary depending on their size, age, and appetite. As a general guideline, feed your Arowana an amount they can consume within a few minutes. It's essential to monitor their eating habits and adjust the portion size accordingly to prevent overfeeding or underfeeding.

How do I know if I'm overfeeding or underfeeding my Arowana?

Overfeeding can lead to obesity, digestive issues, and poor water quality, while underfeeding can result in malnutrition and stunted growth. Signs of overfeeding include uneaten food left in the tank, weight gain, or a bloated appearance. Signs of underfeeding include weight loss, lethargy, and slow growth. To ensure your Arowana is receiving the proper amount of food, closely monitor their eating habits, appearance, and overall health.

Some Arowanas can be picky eaters, making it challenging to provide a balanced diet. To encourage a picky Arowana to eat, try offering a variety of food items, such as insects, fish, and crustaceans, to stimulate their interest. You can also try offering live or frozen food, as the movement can entice your Arowana to eat. If your Arowana still refuses to eat, consult with a veterinarian or fish specialist for further guidance.

What are the signs of a healthy Arowana?

A healthy Arowana will display vibrant colors, clear eyes, and a robust, well-proportioned body. They should be active and responsive to their environment, with a strong appetite and regular eating habits. Healthy Arowanas will also have smooth, undamaged scales and fins, and exhibit regular swimming patterns without signs of distress.

How do I identify and treat common Arowana health problems?

Some common Arowana health problems include fin rot, dropsy, and parasites. To identify these issues, look for signs such as discolored or frayed fins, bloating, loss of appetite, lethargy, or abnormal swimming behavior. If you suspect your Arowana has a health problem, consult a veterinarian or fish specialist for diagnosis and treatment. Maintaining proper water quality, providing a balanced diet, and keeping stress levels low can help prevent many health issues.

What can I do to prevent diseases and parasites in my Arowana?

To prevent diseases and parasites in your Arowana, maintain optimal water quality by performing regular water changes, monitoring water parameters, and using appropriate filtration systems.
