Mastering Arowana Care: Expert Tips and Advice for Unparalleled Success


Arowanas are stunning and majestic freshwater fish that captivate fish enthusiasts around the world. With their vibrant colors, graceful movements, and unique features, Arowanas have become highly sought after by hobbyists and collectors alike. However, caring for these exquisite creatures requires knowledge and attention to detail. In this comprehensive care guide, we will explore everything you need to know to unleash the beauty of Arowanas in your aquarium.

Understanding Arowanas

The Origin and Species of Arowana

The Arowana, also known as the “dragon fish,” originates from the tropical regions of South America, Asia, and Australia. There are several species of Arowana, including the Asian Arowana, South American Arowana, and Australian Arowana. Each species has its unique characteristics and care requirements, but they share common traits such as a streamlined body, long fins, and prominent scales.

Appearance and Varieties

Arowanas are known for their distinctive appearance. They have elongated bodies, large scales, and a mouth that is slightly upturned. The most common varieties of Arowanas are the Asian Arowana and the Silver Arowana. The Asian Arowana comes in different colors, including red, green, and golden, while the Silver Arowana has a beautiful silver metallic sheen.

Natural Habitat

Arowanas are native to the rivers and freshwater habitats of Southeast Asia. In the wild, they are known for their ability to jump out of the water to catch prey. Arowanas thrive in warm, slow-moving waters with plenty of hiding spots and vegetation. Replicating their natural habitat is crucial for their well-being in captivity.

Setting Up the Perfect Environment

Tank Size and Requirements

Arowanas are large fish that require spacious tanks. As juveniles, they can be kept in smaller aquariums, but as they grow, a tank of at least 150 gallons is recommended. Arowanas are excellent jumpers, so it’s important to have a tight-fitting lid to prevent them from escaping.

Water Conditions

Maintaining optimal water conditions is vital for the health of your Arowana. They prefer slightly acidic to neutral water with a temperature range of 75-82°F (24-28°C). Regular water testing and quality monitoring are essential to ensure a stable environment.

Filtration and Lighting

Arowanas require efficient filtration to remove waste and maintain water quality. A powerful filtration system, coupled with regular water changes, helps keep the tank clean and the fish healthy. Additionally, providing adequate lighting that mimics natural daylight is crucial for their overall well-being.

Arowana Feeding and Nutrition

Arowana Care

Dietary Requirements

Arowanas are carnivorous predators and thrive on a diet of live foods and prepared diets. Their diet should consist of high-quality proteins such as small fish, insects, shrimp, and pellets specifically formulated for Arowanas. Offering a varied diet ensures they receive essential nutrients.

Live Foods vs. Prepared Diets

Live foods, such as feeder fish and insects, are highly beneficial for Arowanas. They provide mental stimulation and exercise as the fish hunt their prey. However, prepared diets can also meet their nutritional needs and offer convenience for fish owners. A combination of both is often recommended.

Feeding Schedule and Quantity

Feed adult Arowanas once or twice a day, offering an amount they can consume within a few minutes. Overfeeding should be avoided as it can lead to health issues. Juvenile Arowanas may require more frequent feedings due to their faster growth rate.

Avoiding Common Feeding Mistakes

To ensure optimal health, avoid overreliance on a single type of food and monitor their eating habits closely. Remove any uneaten food promptly to maintain water quality. It’s crucial to strike a balance between providing adequate nutrition and preventing obesity.

Feeding Schedule and Techniques

Arowanas are typically fed once or twice a day, depending on their age and size. It is essential to observe their feeding habits and adjust the quantity accordingly to avoid overfeeding or food waste. To stimulate their natural hunting instincts, you can also consider feeding them live food occasionally.

Maintaining Optimal Health

Disease Prevention and Identification

Preventing diseases is crucial to ensure the long-term health of your Arowana. Maintaining excellent water quality, providing a balanced diet, and avoiding overcrowding are essential steps in disease prevention. Regular observation and awareness of common diseases, such as fungal infections or bacterial diseases, will help you identify any health issues promptly.

Quarantine Procedures

When introducing new fish or plants to your Arowana’s tank, it is advisable to quarantine them first. This helps prevent the spread of diseases or parasites to your existing fish population. Quarantine tanks should have similar water conditions and adequate filtration to ensure the health and well-being of the new arrivals.

Routine Maintenance

Regular tank maintenance is necessary to keep your Arowana’s environment clean and stable. This includes monitoring water parameters, performing partial water changes, and cleaning the tank and equipment. Maintaining a consistent maintenance routine will promote the overall well-being of your Arowana.

Signs of a Healthy Arowana

A healthy Arowana should exhibit vibrant colors, clear eyes, and a voracious appetite. They should swim actively without any signs of lethargy, fin damage, or abnormalities. Regular observation allows you to detect any early signs of illness.

Common Arowana Diseases

Seeking Professional Help

If you notice persistent health issues or are unsure about a specific ailment, consult with an experienced aquatic veterinarian or a knowledgeable fish store. They can provide proper diagnosis and recommend appropriate treatments.

Behavior and Compatibility

Social Behavior

Arowanas are solitary fish in the wild and can exhibit territorial behavior. It’s important to provide them with enough space in the aquarium to establish their territory. Arowanas are also known to jump when they feel threatened or stressed, so ensuring a secure lid is crucial.

Arowana Tankmates and Compatibility

Choosing Compatible Species

When selecting tankmates for Arowanas, consider their size, temperament, and water requirements. Avoid housing them with small, delicate fish that may become prey. Suitable tankmates include large peaceful fish, such as Oscars, Silver Dollars, or Bichir.

Aggression and Territorial Behavior

Arowanas can be territorial and aggressive towards smaller fish. Monitor their behavior closely during introductions. If aggression persists, it may be necessary to separate incompatible tankmates to ensure the well-being of all fish.

Community Tank Options

Creating a community tank with Arowanas is possible, but careful consideration is essential. Large, robust fish that can hold their own against Arowanas are suitable choices. Research the specific requirements and behaviors of potential tankmates to ensure compatibility.

Best Practices for Tankmate Introductions

Introduce new tankmates gradually to reduce stress and aggression. Provide adequate hiding spots and ensure each fish has enough space to establish territories. Monitor their interactions closely and be prepared to make adjustments if necessary.

Breeding Arowanas

Preparing for Breeding

Breeding Arowanas in captivity can be challenging. It requires a separate breeding tank, optimal water conditions, and compatible breeding pairs. Research the specific requirements for your Arowana species and consult experienced breeders for guidance.

Spawning Behavior and Techniques

Arowanas exhibit unique courtship and spawning behaviors. The male may create a nest, and the female releases eggs that are fertilized by the male. After spawning, it’s essential to separate the adults from the eggs to prevent predation.

Caring for Arowana Fry

Arowana fry are initially small and vulnerable. They require a separate rearing tank, optimal water conditions, and a nutritious diet of live foods. Maintaining pristine water quality and providing suitable hiding spots are crucial for their survival and growth.

Challenges and Considerations

Breeding Arowanas can be challenging due to their complex breeding behavior and specific requirements. It requires dedication, experience, and careful planning. Ensure you have the necessary resources and knowledge before attempting to breed Arowanas.

Common Myths and Misconceptions

Arowanas as Feng Shui Symbols

Arowanas are often associated with Feng Shui and considered symbols of luck and prosperity. However, it is important to note that keeping an Arowana solely for Feng Shui purposes may not align with their welfare needs. Arowanas require proper care, spacious tanks, and a suitable environment to thrive.
