Prized for its glimmering scales and sinuous body, the Asian arowana is one of the world's most expensive aquatic creatures, with some rumored to fetch up to $300,000. While not all are priced in the six figures, a young arowana in Singapore could go for $300, while rare adult white albinos could cost $70,000 or more.

Arowana, also known as "dragon fish," are not the typical pet fish. They are bred throughout South East Asia and can grow to be around three feet long (about the size of a snowshoe).
