Aquarium Royalty: How to Care for Your Exquisite Arowana

Welcome to the realm of Aquarium Royalty, where the majestic arowana reigns supreme. Known for their regal appearance and unique characteristics, these fish are more than just pets; they are living treasures. This guide will help you understand the complexities and rewards of caring for your arowana, ensuring that you can provide them with the best possible environment.

Unique Characteristics of Arowanas

Arowanas are among the most fascinating fish in the aquatic world. With their elongated bodies, large scales, and powerful jaws, they command attention. Their eyes are particularly striking, positioned high on their heads, giving them excellent vision above and below the waterline. These fish are known for their ability to leap out of the water to catch insects and small birds, a behavior that has earned them the nickname “dragonfish.”

Their scales are also noteworthy, being large and thick, which protects them from predators. Depending on the species, arowanas can vary in color, from shimmering silver to deep green, adding to their allure. These traits make them not only beautiful but also highly sought after by aquarists around the world.

Ideal Tank Setup

Setting up an appropriate habitat for your arowana is crucial. Given their size and active nature, arowanas require a spacious tank. For a single adult arowana, a tank measuring at least 4 feet in length, 2 feet in width, and 3 feet in height is recommended. Larger tanks are advisable if you plan to keep multiple arowanas or other compatible species.

Ensure that the tank has sturdy supports, as arowanas can be quite heavy. The tank should have a secure lid, as these fish are notorious jumpers. The substrate should be smooth gravel or sand to prevent injuries to their delicate undersides. Decorations such as driftwood and rocks can be added, but ensure they are stable and do not pose a risk of injury.

Water quality is paramount. Use a high-quality filtration system that can handle the bioload generated by these large fish. Regular water changes are essential to maintain optimal water quality. Arowanas prefer calm waters, so avoid strong currents in the tank.

Water Conditions

Arowanas are tropical fish, requiring warm water temperatures between 78°F and 86°F (25°C to 30°C). The pH level should be slightly acidic to neutral, ranging from 6.5 to 7.5. Water hardness should be kept within the range of 5 to 15 dGH. Regular monitoring of these parameters is necessary to ensure the health and well-being of your arowanas.

Regular testing and maintenance of water parameters are crucial. Use a reliable water testing kit to monitor pH, temperature, and ammonia levels. Arowanas are sensitive to changes in water quality, so any deviations should be addressed promptly.

Diet Requirements

Arowanas are carnivorous and thrive on a diet rich in protein. In the wild, they feed on insects, small fish, crustaceans, and occasionally even birds. In captivity, a varied diet of live or frozen foods such as feeder fish, shrimp, worms, and insects can be offered. Pellets specifically formulated for large predatory fish can also be part of their diet.

Feeding should be done sparingly, as overfeeding can lead to health problems. It’s important to observe your arowana’s eating habits and adjust the quantity accordingly. Ensure that the food is appropriately sized for their mouths to prevent choking hazards.

Breeding Habits

Breeding arowanas is a challenging endeavor that requires specialized knowledge and resources. Arowanas are mouthbrooders, meaning the male carries the eggs and fry in his mouth until they hatch. The breeding tank should be separate from the main tank and equipped with a robust filtration system and ample hiding spots.

Conditioning the parents with a nutritious diet prior to breeding is essential. The breeding process can be triggered by increasing water temperature slightly and ensuring there is plenty of live food available. Patience and careful observation are key, as the breeding process can be unpredictable.

Common Health Issues

Arowanas are generally hardy fish when provided with proper care. However, they can be susceptible to certain health issues. Common ailments include fin rot, fungal infections, and parasitic infestations. Regular observation and prompt treatment are vital to maintaining their health.

Maintaining pristine water quality is the first line of defense against many health issues. Quarantine new additions to the tank to prevent the introduction of diseases. If signs of illness are detected, consult with a veterinarian specializing in exotic fish for diagnosis and treatment.

Tips for Maintaining Royal Fish

Caring for arowanas is a rewarding but demanding responsibility. Here are some additional tips to ensure your arowanas thrive:

Patience: Arowanas can take time to acclimate to their new environment. Be patient and give them time to settle in.
Observation: Regularly observe your arowanas for any signs of stress or illness. Early detection can prevent more serious health issues.
Research: Stay informed about the latest care techniques and advancements in arowana husbandry. Join online forums and local clubs to connect with other enthusiasts.
Commitment: Understand that owning arowanas is a long-term commitment. They can live for decades, so be prepared for a lifelong relationship.
