You might have better luck buying the least expensive of the most expensive fish, which are only about, oh, $1,000 to $2,700.
So if that’s considered relatively inexpensive, how much could the most expensive one possibly be? Read on.
The Most Expensive Aquarium Fish
The least expensive of the most expensive aquarium fish are somewhat affordable for an enthusiast who truly wants to own one. They include the candy basslet at $1,000, the golden crossback arowana at $2,000, the clarion angelfish at $2,500, and the wrought-iron butterfly fish, which looks like it’s wrapped in a chain, at $2,700.
Following, however, are the five most expensive fish on record.
Bladefin Basslet
Price: $10,000
It is found mostly in the Caribbean and only grows to about 1.5 centimeters. It swims at a depth of about 700 feet. It often has a white or silvery body with a few wide red or orange stripes.
Masked Angelfish
Price: $20,000
It is usually found around the Hawaiian islands but is rarely seen. As a juvenile, its body is all white, but it has a black area around its face. If it’s a male, its markings will get lighter over time, but the female fish stay the same in appearance.
Peppermint Angelfish
Price: $30,000
The peppermint angelfish is usually striped red and white, like a candy cane. It can be found in tropical reefs and grows to about 7 centimeters. It’s so rare that, as of 2012, it could only be viewed at a commercial aquarium, the Waikiki Aquarium at the University of Hawaii in Honolulu.

Although there are many different types of angelfish, such as this banded or Black Bandit angelfish, the masked angelfish and peppermint angelfish are among the most expensive fish on Earth.
Freshwater Polka Dot Stingray
Price: $100,000
One of the most unique-looking fish, the freshwater polka dot stingray is shaped like a basic oval-shaped stingray. Its body, however, is black with white polka dots. Adults can measure 18 inches in diameter. It might be hard to differentiate one from rocks, as it buries itself in the sand during the day.
And the rarest and most expensive fish on record?
Platinum Arowana
Price: A whopping $400,000
Although it’s found on several continents, it’s the rarest and most expensive fish in the world. It’s a freshwater fish that has a slim, long, platinum-colored body with metallic scales, which give it a glow unlike any other. Its large scales make its shine even more pronounced.
