The Right Tank Size

Arowanas are large, active fish that require ample swimming space. A minimum tank size of 180 gallons is recommended for a single arowana, but larger tanks are even better. Something like the 220 Gallon Half Moon Fish Tank or the 170 Gallon White Fish Aquarium would be an excellent choice. These tanks provide enough room for your arowana to thrive and grow to its full potential.

Remember, the larger the tank, the easier it is to maintain stable water conditions, which are crucial for arowana health.

Water Conditions

Arowanas are tropical fish that prefer warm, slightly acidic water conditions. Aim for a temperature range of 78°F to 84°F and a pH level between 6.5 and 7.5. Regular water changes (20-30% weekly) are essential to maintain good water quality and remove excess waste and toxins.

Diet and Feeding

In the wild, arowanas are apex predators that feed on a variety of live prey, including smaller fish, insects, and crustaceans. In captivity, they should be fed a varied diet of high-quality protein sources, such as:

  • Live or frozen feeder fish (e.g., goldfish, guppies, or rosy red minnows)
  • Freeze-dried or frozen krill, shrimp, or insect larvae
  • Sinking pellets or gel food formulated for large carnivorous fish

A product like the HARTZ Wardley Pond Floating Fish Food Pellets can be an excellent addition to your arowana’s diet, providing essential nutrients and variety.

It’s important to feed your arowana an appropriate amount based on its size and age, typically 2-3 times per week, to prevent obesity and maintain good health.

Tank Mates and Compatibility

Arowanas are known for their predatory nature and territorial behavior, making them challenging tank mates for most other fish species. They are often best kept alone or with other aggressive, similarly-sized fish that can hold their own, such as large cichlids or other arowana species.

If you do decide to keep your arowana with other fish, it’s crucial to provide ample hiding spaces and ensure that the tank is large enough to accommodate their territorial tendencies. Some potential tank mates for arowanas include:

  • Larger cichlids (e.g., Oscar, Green Terror, or Jack Dempsey)
  • Larger catfish species (e.g., Redtail Catfish or Striped Raphael Catfish)
  • Other aggressive or semi-aggressive fish of similar size (e.g., Bichir or Snakehead)

However, it’s important to note that compatibility can vary based on individual temperaments, and introducing new fish to an established arowana tank should be done with caution.

Arowana Care Sheet – Common Diseases

Despite their resilience, Arowanas are susceptible to various health issues, including bacterial infections, parasites, and nutritional deficiencies. Keep a close eye on your fish for any signs of distress, such as loss of appetite, lethargy, or abnormal behavior. Quarantine new additions before introducing them to your main aquarium to prevent the spread of diseases, and maintain excellent water quality to boost their immune system and prevent stress-related illnesses.
