10 Super Expensive Fish for your Home Aquarium

When setting up a fish tank, you can fill them up with some of the most affordable fish to expensive ones.

You may argue that when not many people can afford them, what’s the need to introduce them.

I agree with all this, but you forget one crucial fact: many aquarists like to boast about their fish tank.

Well, after spending this high amount of money, WHY SHOULDN’T THEY?

So, you can find these 10 fishes on the expensive side, there’s not much you can do but adore these beautiful aquatic creatures.


The Arowana is a freshwater fish native to South America.

You can find them in the Amazon River, where it feeds on smaller fish, insects, frogs, and other small animals.

The name “Arowana” comes from the Malay word for dragonfish.

The price of an Arowana depends on its size and coloration.

But this species typically sells for about $1 per inch when it is between 16 and 24 inches long.

For example: if you want to buy a 20-inch specimen with red scales around its body (and not yellow ones), you should expect to pay around $10,000!

Platinum Arowana

The Platinum Arowana is a freshwater fish that can grow up to 1 foot long.

This large, predatory tropical aquarium fish is also hardy and easy to care for.

However, it is not a beginner’s fish and requires professional care.

The Platinum Arowana has been reported to live for 30 years in captivity and grow up to 5 pounds!

Peppermint Angelfish

Peppermint Angelfish is a type of saltwater fish.

You can find these marine fish in freshwater aquariums or bathtubs!

Peppermint Angelfish are usually easy to care for and make great pets. This fish usually costs around $30,000.

Black Tang

Black tang is a saltwater fish that is a marine fish.

It is rare and costly, with some specimens being sold for as much as $12,000.

However, black tangs are very beautiful, colorful creatures and make great pets for those who can afford them.

Dragon Moray

The Dragon Moray (Gymnothorax polyuranodon) is a carnivore that eats smaller fish, crustaceans, and mollusks.

It has no vicious bite but can inflict painful wounds with its strong jaws.

The Dragon Moray is an eel-shaped fish with elongated dorsal and anal fins that propel the body through the water.

You can find this species in coral reefs and algae beds of shallow waters in tropical environments worldwide.

The Dragon Moray requires an aquarium of at least 90 gallons with a sandy bottom and plenty of hiding places for its prey items to live in.

The ideal temperature for this species ranges between 72-82 degrees Fahrenheit.

They tend to hide during the day, so be sure not to disturb them when cleaning your aquarium, as they will bite if startled!

Freshwater Polka Dot Stingray

The Polka Dot Stingray is an intriguing fish that has become increasingly popular in the aquarium trade.

It is a freshwater ray, and it can be found in areas of Southeast Asia such as Indonesia and Malaysia.

The Polka Dot Stingray will grow 6 to 8 inches long; this makes them ideal for medium-sized aquariums or large fish bowls!

They have large eyes and small mouths with prickly teeth, which help them catch prey like plankton, insects, larvae, and crustaceans (but not other rays).

Their bodies are brownish with white dots patterned everywhere except on their tails, where they have blueish/purple coloration instead!

This fish species require warm waters at most minuscule 24°C (75°F) so make sure your tank heater isn’t too powerful if you want these guys around for a while 🙂

Clarion Angelfish

Clarion Angelfish is one of the most expensive fish in the world. It is a freshwater fish and a member of the Cichlid family.

The Clarion Angelfish is a hybrid of two species of Angelfish: Aulonocara ellioti and Pseudotropheus zebra.

The first species was bred with another African cichlid named Labeotropheus fuelleborni to create this beautiful creature.

The Clarion Angelfish’s colors vary from orange-red or yellow to brown or blue, depending on its age and diet at that time, though they always have black spots covering their bodies.

Their eyes are also black like other angelfish species; however, they can be distinguished by their long fins that extend beyond their body length by several inches (up to 10 cm).

This makes them look very elegant as they swim around inside your home aquarium!

Masked Angelfish

The masked angelfish is one of the most colorful and attractive species in the aquarium trade.

With its orange-and-white stripes, red tail fins, and black mask, it’s a showstopper.

Unfortunately, it can grow up to 9 inches long and requires a large fish tank to thrive.

The masked angelfish are often sold under different names, including the firefish or imperial angelfish.

It’s easy to look at these fish and think they are one of several types of marine angelfishes that live in the deep waters off Florida and Bermuda or Australia’s Great Barrier Reef.

But this isn’t true: Masked Angels are freshwater fish from South America. They are similar to marine angelfishes but have very different requirements when kept as pets!

Masked Angels need plenty of room for swimming with plenty of places to hide if they feel threatened by other tank mates such as aggressive cichlids or other large fish species (such as Oscars).

Even though they’re small when first purchased, they’ll quickly outgrow any small aquariums, so plan if you want them!

The best way to keep them would be through breeding which should only happen with two adults.

Unless your tank has breeding chambers installed beforehand, young ones cannot survive without parental care during those first few weeks after hatching.”

Goldflake Angelfish

Goldflake Angelfish is a freshwater fish that belongs to the family Centropyge.

It is a prevalent aquarium fish because it is hardy, active, and colorful.

This beautiful species has an orange stripe that runs along its body from head to tail.

The fins are also orange with small white spots on them. Goldflake Angelfish can grow up to 6 inches long when fully grown.

Still, in captivity, they tend to stay smaller at around 4 inches long as they have less space in an aquarium than they would in their natural habitat, which is usually found in coral reefs or lagoons where they swim freely throughout the day looking for food before returning home at night when no predators are around.

Hence, you need an open tank if you want your Goldflake Angelfishes (also known as Red Sea Sailfin Tang) to swim freely without worrying about escaping into another tank or being eaten by other fish!

Mandarin fish

Mandarins are freshwater and tropical fish that need warm water to thrive.

A healthy Mandarin will live 5 to 10 years, but they can live up to 20 years in captivity.

This species is very popular with aquarium hobbyists because of its beauty and hardiness.

In addition, these fish are omnivorous and eat a wide variety of foods like flake food, pellets, and brine shrimp.

Why are These Fish So Expensive?

There are many reasons for the high cost of some fish. Some are rare, others are beautiful, and some have exotic features that make them expensive.

Besides, when these fish are harder to find in stores and even harder to catch by yourself, their price tends to skyrocket.

Most people who keep aquariums prefer not to catch fish because they do not want them stressed out or injured during the process.

Also, buying live food usually costs less than catching it yourself (unless you live near a pond where there’s plenty of food).

Some species of freshwater fish will cost thousands of dollars simply because they’re so rare that few people would ever see one outside of an aquarium or zoo enclosure—let alone own one themselves!

The price tag? Around $10K each…and rising quickly too!

How Can You Provide Best Care to These Expensive Fish

There are several factors that affect the care of these expensive fish. Here are some tips to help you provide them with a healthy environment:

  • Water quality is paramount for most aquarium fish but is essential for costly species.
  • It’s not just about having clean water; you also need to ensure that the pH level and temperature are within an acceptable range. It’s essential to test your tank regularly to keep tabs on what changes need to be made to keep things running smoothly.
  • Careful feeding is another crucial aspect of maintaining an aquatic ecosystem inhabited by precious creatures such as these expensive saltwater fish or freshwater aquarium fish breeds (or any other type of pet or animal). You must ensure that your fish have access to enough food at all times; if there isn’t enough food available, this could lead them to think about cannibalizing each other since they’d rather eat something than starve! This would be detrimental because it would cause stress, and the lack of nutrients will lead directly to death!


So, these are the most expensive fish in the world.

They cost a lot of money and can be hard to maintain because of their unique needs.

If you have enough money to spend on aquariums and want something unique, these may be right up your alley!

But if you’re looking for some cheap fish that won’t break the bank, there are plenty more options than these 10 fish species.
