The Complete Guide to Arowana Care

Arowana are among the most striking freshwater fish in the hobby, prized for their sleek, dragon-like appearance and cultural significance in many parts of Asia, where they’re considered a symbol of good fortune.

Tank Size

Arowana grow large — often two to three feet in length — and need a correspondingly enormous tank, typically 250 gallons or more for a fully grown adult, along with a very secure, weighted lid since arowana are powerful jumpers.

Water Quality

As a large, high-bioload predatory fish, arowana need robust filtration and consistent large water changes to keep ammonia and nitrate in check. Review Understanding Aquarium Water Parameters if you’re new to monitoring these levels.

Diet

Arowana are carnivorous predators, accepting a diet of quality pellets, feeder fish, insects, and other protein-rich foods as they mature.

Long-Term Commitment

Arowana can live for decades with proper care, so prospective owners should be prepared for a very long-term commitment and the substantial cost of a suitably sized tank and filtration system.
