Bladefin Basslet ($11,000)
The Bladefin Basslet is another greatly rare fish, which can only be found using a submersible. Measuring in at about 1.5 inches or 3cm, this unique looking reef fish lives at depths of 500 feet, and it was collected by a submersible in Curacao for the first time.
Since then, it became quite a popular yet vastly unaffordable tank fish, as it was sold on numerous occasions for more than $10,000.
Masked Angelfish ($20,000)
While there are plenty of colourful fishes on our list, the Masked Angelfish impresses with a monochrome look and a very beautiful masked figure. Genicanthus personatus lives in the Northwestern Hawaiian Islands, at the very edge of conventional diving limits.
Peppermint Angelfish ($20,000+)
It’s difficult to measure the exact worth of the Peppermint Angelfish, mainly because this fish surfaced (no pun intended) with various price tags over the years. At first, it was purchased for $30,000 by a collector and was put on display.
However, more specimens arrived on the market in the following years, with some boasting much more collector-friendly price tags of about $19,000. That’s still a lot of money to pay for a 2.7-inch exotic fish.
Freshwater Polka Dot Stingray ($100,000)
The last two fish on our list come with some ridiculously high price tags. For $100,000, the Freshwater Polka Dot Stingray is one of the most expensive fish in the world and the most expensive aquarium fish in Taiwan.
Also known as the Xingu River Ray, it can be found in Brazil’s Xingu River, and it can reach up to 18 inches in diameter. It’s also worth noting that females are usually larger than males. While most stingrays give birth to around four young ones.
Platinum Arowana ($300,000 – $400,000)
It’s hard to believe that a fish would be worth almost half a million dollars, but here we are! The Platinum Arowana is widely regarded as the world’s most expensive fish and this makes sense right?
After all, it has Platinum in its name. Jokes aside, the Platinum Arowana is an incredibly beautiful fish. Some even believe that it brings good luck, but if you’re rich enough to afford one of these, you’re probably quite lucky already.
