The Arowana is a huge fish that comes from the Amazon River! They can reach 4 feet in length and are not recommended for beginners. They require a very large tank, 300+ gallons. Also, you will need a very good filter with high gallons per hour output rate. A Fluval Canister Filter would be perfect for a large tank and a fish of this size.
