Number one on the list is the Platinum or White Arowana. This fish has a value of approximately $400,000. It is so valuable that a micro ID chip is implanted into it before it reaches sexual maturity to help identify and authenticate it. The color is the result of a very rare genetic mutation. More common types of Arowana include: the Red Arowana, Green Arowana, Yellow-Tail Arowana, Silver Arowana, Black Arowana and Australian Pearl Arowana. They are found in nature in South America, Southeast Asia and Africa. In captivity they require at least a 300 gallon tank with plenty of live food such as crickets and worms. They can reach a size of about 35 inches and they can live for more than 50 years. They are intelligent with the ability to recognize individuals and they can be trained to be hand-fed. Although they are a fabulous fish, they are not necessarily the perfect pet for the average home aquarist for some of the reasons listed above.
