Basically, there are three types of Australian Arowana; the Pearl, Golden Pearl and the Red Pearl Arowana, which is rarest of all. The Pearl arowana, scientific name scleropage jardini, is also called with several other names such as the Gulf Saratoga, Northern Barramundi and Australian bony tongue. It is similar to the Asian Golden Arowana and sometimes pass off and sold as one in Asia by scamp dealers since the Pearl Arowana is the next most expensive after it.

Do not forget to clean or remove any fragments of food that are left uneaten to maintain a healthy environment inside the aquarium.
