How to Feed an Arowana

Arowana are large-scaled, omnivorous fish from Asia and South America. They eat a variety of food in captivity, including prepared pellets, shrimp, insects and live or dead feeder fish. Often sold as small babies, they grow quickly and can reach up to 48 inches in length. They need a large aquarium. Minimum size for an adult arowana is 300 gallons. They are best kept alone or with fish of other species that are similar in size, as they are aggressive toward other arowana and may make a meal out of smaller tank mates.

Instructions

    • 1

      Feed floating pellets formulated for arowana. They are available at pet stores and provide a complete diet. Follow the instructions from the manufacturer.

    • 2

      Quarantine feeder fish for at least 24 hours before adding them to an arowana's tank to make sure they are healthy. Live fish can carry diseases that can be transmitted to the arowana.

    • 3

      Feed insects by scattering them on the surface of the water. Arowana tend to feed at the surface, so floating insects are easy for them to pick up.

    • 4

      Feed pieces of shrimp or fish by hand, or by using tweezers or tongs. Arowanas do not have dangerous teeth, so it is safe to put your hand in the tank.
