Pearlscale Goldfish: The Fascinating Fancy Fish

Goldfish are one of the most iconic freshwater fish in the world, with their flashy fins and beautiful colors. Among the many varieties of goldfish, pearlscale goldfish stand out as one of the fanciest and most unique.

This article will provide an overview of pearlscale goldfish, their care requirements, and all the fascinating facts that make them so special. Pearlscale Goldfish Facts & Overview:

Care Level:

Pearlscale goldfish are relatively easy to care for, making them a suitable choice for beginner aquarists.

However, they do require a bit more attention and maintenance than other common goldfish species. Temperament:

Pearlscale goldfish are generally peaceful and docile fish, which makes them great companions for other community fish.

However, during breeding season, they may become slightly aggressive towards other fish. Color:

Pearlscale goldfish have a beautiful and unique appearance with a pearlescent scale pattern that shimmers in the light.

These colors can vary from white to blue, red, black, and chocolate brown. Lifespan:

With proper care and maintenance, pearlscale goldfish can live up to 10-15 years in captivity.


On average, pearlscale goldfish can grow up to 6-8 inches in length, making them a relatively small goldfish breed. Diet:

These fish are omnivores, meaning they eat both animal and plant-based foods.

A balanced diet of both live and prepared foods should be provided. Some suitable food options include brine shrimp, bloodworms, and flakes.

Minimum Tank Size:

Pearlscale goldfish require a larger tank to thrive compared to other common goldfish. A minimum tank size of 20 gallons is recommended for a single fish, with an additional 10-20 gallons per additional fish.

Tank Setup:

The tank should have a substrate made of small gravel or sand as pearlscale goldfish have a delicate stomach. The tank should also have plenty of plants, rocks, and hiding spots to ensure that the fish feel comfortable.


Pearlscale goldfish are generally compatible with other peaceful fish, but avoid mixing them with aggressive species. It is also important to avoid overstocking the tank as it can affect the water quality, potentially harming the fish.


In summary, pearlscale goldfish make great pets for those looking for a fancy fish with unique features. With their peaceful temperament, balanced diet requirements, and relatively easy care needs, these little fish are a great choice for beginners and experienced aquarists alike.

By providing a suitable tank setup, a healthy diet, and plenty of love and attention, pearlscale goldfish can lead a long and happy life in captivity. So, why not add a little bit of shimmer and shine to your fish tank with a pearlscale goldfish?

3) Appearance & Behavior

Pearlscale Goldfish are known for their unique appearance, with scales that resemble tiny pearls. Unlike other goldfish, the scales on a pearlscale are raised, making it appear as though they are covered in small bumps.

While the scales are the defining characteristic of the pearlscale, these lovely creatures have an array of bright colors, including metallic blue, orange, and red.

The unique appearance of a pearlscale may also be distinguished by its swimming style, which tends to be slower than other goldfish.

The pearlscale swims in a zig-zag motion, and its swimming style is characterized by a shorter, rounder body that moves from side to side. This swimming style is in part due to their larger, rounded body shape.

Pearlscales are not known for their speed, but this only makes their slightly whimsical swimming style more endearing to those who care for them. Distinguishing between male and female pearlscale goldfish is pretty straight forward; males will have white breeding stars (small white dots) that appear on their pectoral fins during the breeding season, indicating sexual maturity.

Females, on the other hand, tend to have a rounder body shape and may appear slightly larger in size. Female pearlscales may also have a slightly more rounded dorsal fin.

You can differentiate between sexes quite accurately once the fish are mature. Young pearlscale fry can be more challenging to tell apart.

While goldfish may not be the most intelligent fish, pearlscale goldfish are known for their curiosity and inquisitive nature. They are highly active and exhibit a curious disposition.

They are not the type of fish that will grow bored or sullen in a basic fish tank environment. Providing adequate hiding spaces, foliage, and places to explore may bring out the best in these fascinating and colorful fish.

4) Pearlscale Goldfish Care

While some fish may require extensive and specialized care, pearlscale goldfish make excellent pets because they are generally easy to care for. Pearlscale Goldfish, in particular, are known to require less attention than other goldfish.

They thrive in freshwater environments with moderate water movement, minimal active filtration, and the right water temperature and pH levels. Maintaining the water parameters in your pearlscale goldfish tank is vital to their health and well-being.

A water temperature between 65 and 72 degrees Fahrenheit is ideal for pearlscale goldfish, and the pH levels should always remain between 6.8 to 7.5. Although goldfish are known to be hardy fish, extremely cold or hot temperatures can harm them, making it essential to keep an eye on the thermometer.

The size of the tank is an essential factor in the care of pearlscale goldfish.

Ideally, a single pearlscale goldfish requires a minimum tank size of 20 gallons. Pearlscalers can grow relatively large, making it essential to have a large amount of water to dilute waste.

Overcrowding can impact their health, as well as increase the chance of their getting diseases, so it’s best to limit the number of fish according to the size of the tank. Providing adequate swimming space is critical for pearlscale goldfish.

Keeping the water cool and clean with filters is an important aspect of determining which fish are compatible with your pearlscale goldfish.

While plants, rocks, and other hiding spaces might make setting up your goldfish tank more complex, these elements can create a natural and cozy environment for your fish.

There are also plants that these fish find particularly appealing. Vegetables such as spinach and peas are also nourishing dietary supplements for goldfish.

These leafy greens can be purchased at your local pet store, or you can create your own by blanching fresh vegetables.

It is essential not to overfeed your pearlscale goldfish, as they are prone to swim bladder issues due to overeating.

Their nutritional requirements should also be taken into account when allocating food rations. Give them a wide selection of live, frozen, and dry foods to enhance their health.

Dry foods can be supplemented with peas or spinach to improve their nutrient intake. An important aspect of pearlscale goldfish care is combating disease, which can be brought on by poor water quality or overfeeding.

Swim Bladder Disease is a common ailment for goldfish that can alter their swim behavior. Avoiding overfeeding, providing a nutritious diet, and maintaining optimal water conditions is all significant in preventing this disease from developing.

Fungal infections, parasitic infections, and other bacterial illnesses may also occur if the aquarium water or the fish themselves aren’t kept clean. Performing regular water changes is an essential aspect of caring for healthy and happy pearlscale goldfish.

In conclusion, pearlscale goldfish are an excellent addition to any home aquarium. While they are generally easy to care for, it is crucial to keep environmental factors such as water temperature, pH levels, and tank size in mind.

Providing healthy plants, ample swimming space, and a range of food choices can create a happy and cozy environment for your pearlscale goldfish. By keeping your fish healthy and well-fed, you can enjoy their inquisitive and playful nature for many years.

5) Breeding Pearlscale Goldfish

Breeding the pearlscale goldfish involves creating the ideal aquarium environment and carefully pairing the males and females. You will need to ensure that both fish are mature, healthy, and ready to spawn.

Here is a detailed guide on how to breed pearlscale goldfish. Setting Up Breeding Tanks:

One essential element of breeding pearlscale goldfish is setting up a breeding tank.

The breeding tank should be at least 20 gallons, with an adequate filtration system installed. To prevent eggs and fry from being sucked into the filter, use a pre-filter sponge or wrap the intake of the filter in cloth.

The water should be kept clean, and water changes should be performed regularly. You should also add bushy plants or other hiding spaces to encourage spawning and provide the fry with a safe haven.


Pearlscale goldfish breeding requires stable water temperature. The optimal temperature for spawning is 75F.

You can increase the temperature slowly to 82F when it’s time for spawning. Pairing:

Males and females can be paired up for breeding if they have reached maturity.

Maturity time may differ for males and females. Males tend to reach sexual maturity sooner than females.

When choosing a pair, it is essential to select fish that share similar body parameters, such as body shape and size. You can create a ratio of one male to two females to reduce any aggression and competition among the males.


The actual process of spawning involves the female depositing eggs and the male releasing sperm that fertilizes the eggs. When the time is right, you may notice the male chasing the female around the breeding tank.

The female will then lay eggs on the plant leaves or the aquarium bottom. The male will then release sperm over the eggs, fertilizing them.

The process will be repeated several times until the female has deposited all her eggs. Caring for Eggs and Fry:

Once the eggs have been fertilized, they will appear clear and transparent, later becoming opaque.

The eggs will hatch in 48 to 72 hours, depending on the water temperature. After they hatch, the fry will remain attached to their yolk sacs for around four to five days.

As the fry absorb the yolk sacs, they should be fed infusoria or finely crushed baby fish food. After 10-14 days, they will be able to eat the same types of food as adult pearlscale goldfish.

6) Conclusion

In conclusion, pearlscale goldfish are fascinating creatures that make excellent aquarium pets. They are easy to care for, making them suitable for aquarium enthusiasts of all experience levels.

The unique appearance of pearlscale goldfish, with their raised, pearl-like scales and bright colors, adds a splendid touch to any aquarium. If you are interested in breeding your pearlscale goldfish, creating a suitable environment with a breeding tank, proper pairing of males and females, and providing adequate care for the eggs and fry will enable successful breeding.

With time and attention, these lovely creatures will thrive, adding beauty and tranquility to your living space. In summary, pearlscale goldfish are a popular and fascinating species of goldfish that require proper care and attention to thrive.

Their unique appearance, peaceful temperament, and easy care needs make them a great addition to any aquarium. Providing a suitable tank setup, proper water parameters, a balanced diet, and prevention of diseases are essential for their health.

Breeding pearlscale goldfish also requires specific attention to the aquarium environment and the pairing of male and female fish. Overall, pearlscale goldfish offer an enjoyable and rewarding experience for aquarium enthusiasts and should be considered for their unique characteristics and peaceful nature.
