The next fish on this list isn't your average aquarium fish. It's a delicacy used for sushi - bluefin tuna. This species is the most expensive fish in the world, and is kept in high-end aquariums due to its endangered status. Bluefin tuna can be found in Japan, Monterey Bay, and other large aquariums, but domestic aquariums cannot sustain them.
Conservation efforts have been underway for decades, and more aquariums are joining the cause. The freshwater polka dot stripe is partly illegal in the United States.

What makes fish so expensive is its unusual appearance and the fact that Japanese breeders rarely export their fish. These fish need a large tank to house them, but they're an incredible addition if you have space for one in your tank. The Arowana is a symbol of good luck and prosperity in Chinese culture, also known as dragon fish. Fish are popular as food and as pets, leading to the domestication of many new species of fish in recent decades.
