PearlScale Goldfish Care: Tank Setup, Diet, Tank Mates, Diseases & More!

If you’re looking for a unique and eye-catching addition to your aquarium, a pearl scale goldfish might be just what you need. These beautiful fish have a distinctive appearance, with round, pearl-like scales that give them a shimmering, almost metallic look. However, caring for pearl scale goldfish requires some specific knowledge and attention to detail.

Pearlscale Goldfish require a tank size of at least 20 gallons per fish, pH levels between 6.0-8.0, and a temperature range of 65-78°F. They are omnivores and need a varied diet of high-quality pellets or flakes, vegetables, and occasional live or frozen foods. Regular water changes and tank maintenance are also important for their health. They also require a soft substrate to prevent damage to their delicate fins.

First and foremost, it’s important to ensure that your pearl scale goldfish has a suitable environment to thrive in. They require a tank that is at least 20-30 gallons in size, with a filter and aeration system to maintain water quality.

Additionally, pearl scale goldfish do best in water that is slightly alkaline, with a pH between 7.2 and 7.6.

When it comes to feeding your pearl scale goldfish, a balanced diet is key. They require a mix of both plant-based and protein-based foods, such as flakes, pellets, and frozen or live brine shrimp.

However, it’s important not to overfeed your fish, as this can lead to health problems. With the right care and attention, your pearl scale goldfish can be a stunning addition to your aquarium for years to come.s

Pearl Scale Goldfish Care: Everything You Need to Know

Species Summary

If you’re thinking of adding a pearl scale goldfish to your aquarium, it’s important to understand the basics of their species. Here’s a quick summary of what you need to know:


Pearl scale goldfish are a type of fancy goldfish that originated in China. They were selectively bred from the wild Prussian carp, which is native to East Asia.


On average, pearl scale goldfish can live for 10-15 years in captivity if they are cared for properly.


One of the most distinctive features of pearl scale goldfish is their rounded, pearl-like scales.

These scales are larger and more pronounced than those of other goldfish breeds, giving them a unique appearance. They also have a short, rounded body and a double tail fin.


Pearl scale goldfish typically grow to be around 6-8 inches in length, although some can grow larger.

Growth Rate

The growth rate of pearl scale goldfish can vary depending on factors like water quality and diet. They typically grow more slowly than other goldfish breeds, so it’s important to be patient when raising them.

Behavior & Temperament

Pearl scale goldfish are generally peaceful and can be kept with other goldfish breeds. However, they can be somewhat shy and may hide if they feel threatened.

Male vs Female

It can be difficult to tell the difference between male and female pearl scale goldfish, especially when they are young. However, males may have small white bumps on their gill plates during breeding season.

Overall, pearl scale goldfish are a unique and interesting addition to any aquarium. With proper care and attention, they can thrive for many years and provide you with endless hours of enjoyment.

Personally, I have found that my pearl scale goldfish is a great conversation starter and always draws attention from guests.

Tank Setup

When it comes to keeping Pearl Scale Goldfish, setting up the perfect tank is crucial. Here are some things to consider:

Tank Size

The minimum recommended tank size for one Pearl Scale Goldfish is 20 gallons.

However, you should aim for a larger tank if possible, as these fish can grow up to 8 inches in length. A larger tank will also provide more swimming space and help maintain better water quality.


Lighting is important for both the health of your fish and the growth of any plants in the tank. Aim for 8-12 hours of light per day and consider using a timer to make sure the lighting is consistent.

Avoid placing the tank in direct sunlight as this can cause algae growth and temperature fluctuations.

Filtration & Aeration

A good filtration system is essential for maintaining water quality in your tank.

Look for a filter that can handle at least 2-3 times the volume of your tank. Aeration is also important, as it helps oxygenate the water and improve the health of your fish.


Pearl Scale Goldfish prefer water temperatures between 68-72°F.

A heater can help maintain a consistent temperature in your tank, especially during colder months or in rooms with fluctuating temperatures.


Choose a substrate that is gentle on your fish’s delicate fins, such as sand or small-grain gravel. Avoid sharp or rough substrates that can damage your fish. A depth of 2-3 inches is recommended.


Decorations not only add visual appeal to your tank but also provide hiding places for your fish.

Choose decorations that are smooth and won’t harm your fish. Avoid decorations with sharp edges or small holes that your fish could get stuck in.


Live plants can provide oxygen, filtration, and hiding places for your fish.

Choose plants that are compatible with your fish and tank setup. If you’re unsure, ask a professional at your local pet store for advice.

Overall, setting up the perfect tank for your Pearl Scale Goldfish takes a little time and effort, but it’s well worth it for the health and happiness of your fish.

Personally, I found that adding live plants to my tank not only improved the water quality but also gave my fish a more natural and stimulating environment to swim in.

Water Quality

One of the most important aspects of pearl scale goldfish care is maintaining good water quality.

Poor water quality can lead to a range of health problems for your fish, so it’s essential to keep the water clean and well-maintained.

Water Temperature

You should aim to keep the water temperature in your pearl scale goldfish tank between 68°F and 74°F. This range is comfortable for most goldfish breeds, including pearl scales.

It’s important to avoid sudden fluctuations in temperature, as this can be stressful for your fish and lead to health problems.

Water pH

The ideal pH range for pearl scale goldfish is between 7.0 and 8.4. It’s important to monitor the pH levels regularly and make adjustments as necessary to keep the water within this range.

A pH that is too high or too low can cause stress and health problems for your fish.

Water Hardness

Pearl scale goldfish prefer moderately hard water, with a range of 100-250 ppm.

It’s important to test the water hardness regularly and make adjustments as necessary to keep it within this range. If the water is too soft or too hard, it can cause health problems for your fish.

Water Changes

To maintain good water quality, you should perform regular water changes. Aim to change around 20-30% of the water in your tank every week.

This will help to remove any waste and debris from the water, as well as replenish important nutrients and minerals.

Personally, I like to use a siphon to clean the gravel in my pearl scale goldfish tank during water changes. This helps to remove any excess waste and debris that may have accumulated on the bottom of the tank.

It’s also important to use a dechlorinator when adding new water to the tank, as chlorine can be harmful to your fish.

Tank Maintenance

Keeping your pearl scale goldfish healthy and happy requires regular tank maintenance. Here are a few tips to help you keep your tank in top condition:

  • Change the water regularly: You should change 20-30% of the water in your tank every week. This will help keep the water clean and clear, and remove any harmful chemicals or waste products that could harm your fish.
  • Clean the tank: Use a gravel vacuum to clean the substrate and remove any uneaten food or waste. Scrub the sides of the tank with an algae scraper to remove any algae buildup.
  • Check the filter: Your filter is the heart of your tank, so it’s important to keep it clean and functioning properly. Check the filter media regularly and replace it as needed.
  • Test the water: Use a water test kit to check the pH, ammonia, nitrite, and nitrate levels in your tank. If any of these levels are too high, you may need to take action to correct them.

Personally, I find that cleaning my tank is a relaxing and enjoyable activity. It’s a great way to bond with your fish and ensure that they have a clean and healthy environment to live in.

By following these simple tips, you can keep your pearl scale goldfish happy and healthy for years to come.

Tank Mates

Compatible Fish Species

If you’re looking to add some friends to your pearlscale goldfish tank, there are a few species that can coexist peacefully. Some compatible fish species include:

  • White Cloud Mountain Minnows
  • Zebra Danios
  • Corydoras Catfish
  • Otocinclus Catfish

These fish are all relatively small and peaceful, and won’t compete with your pearlscale goldfish for food or territory. They also prefer similar water conditions, so your tank won’t require any major adjustments.

Incompatible Fish Species

While there are some fish that can live happily alongside pearlscale goldfish, there are others that simply won’t get along. Some incompatible fish species include:

  • Betta Fish
  • Cichlids
  • Angelfish
  • Gouramis

These fish are known to be more aggressive or territorial, and may harm or stress out your pearlscale goldfish. It’s best to avoid adding them to the same tank.

Can Pearlscale Goldfish Live with Other Goldfish?

Yes, pearlscale goldfish can live with other goldfish, but there are a few things to keep in mind. First, make sure the tank is large enough to accommodate multiple fish.

A general rule of thumb is to have at least 20 gallons of water per goldfish.

Second, choose goldfish that are similar in size and temperament. Mixing large and small goldfish can lead to bullying and competition for food. Similarly, mixing aggressive and peaceful goldfish can lead to stress and injury.

Finally, keep an eye on the water quality. Adding more fish to a tank can increase waste and decrease water quality, so make sure to perform regular water changes and monitor the tank’s parameters.

Personally, I’ve had success keeping my pearlscale goldfish with other goldfish of similar size and temperament. They love to swim and play together, and it’s always fun to watch their different personalities shine through.


Feeding your pearl scale goldfish a healthy and balanced diet is crucial for their overall health and well-being. Here’s what you need to know about their diet:

What To Feed

When it comes to feeding your pearl scale goldfish, a high-quality pellet or flake food specifically formulated for goldfish is a good place to start.

Look for brands that are low in fillers and high in protein. You can also supplement their diet with fresh or frozen vegetables such as peas, spinach, and zucchini.

These provide important nutrients and fiber that help to keep their digestive system healthy.

I also like to give my pearl scale goldfish occasional treats such as bloodworms or brine shrimp. These are high in protein and are a great way to add variety to their diet.


It’s important to feed your pearl scale goldfish small amounts several times a day rather than one large feeding.

This helps to prevent overeating and reduces the risk of digestive problems. Aim to feed them 2-3 times a day, and only give them what they can consume in a few minutes.


Here are some tips to keep in mind when feeding your pearl scale goldfish:

  • Remove any uneaten food from the tank after feeding to prevent it from decomposing and polluting the water.
  • Don’t overfeed your goldfish, as this can lead to health problems such as swim bladder disorder.
  • Make sure the food you’re feeding them is appropriate for their size. Pellets that are too large can be difficult for them to swallow.
  • Consider using a feeding ring or floating food dispenser to prevent the food from sinking to the bottom of the tank and getting lost in the substrate.

By following these tips and providing your pearl scale goldfish with a healthy and varied diet, you can help ensure they live a long and happy life.

Common Diseases


As a pearl scale goldfish owner, you may encounter some common diseases that can affect your fish. These diseases include:

  • Ich
  • Fungus
  • Fin Rot
  • Swim Bladder Disease


The symptoms of these diseases can vary.

You may notice that your fish has white spots on its body, torn fins, or is having trouble swimming. Other symptoms may include lethargy, loss of appetite, and abnormal behavior.


If you notice any of these symptoms, it’s important to take action quickly. Treatments for these diseases may include medications, water changes, and adjusting the temperature and pH levels of your tank.

Always follow the instructions on any medication you use, and be sure to remove any activated carbon from your filter before treatment.


The best way to prevent these diseases is to maintain a clean and healthy environment for your fish. This includes regular water changes, avoiding overfeeding, and providing a balanced diet.

Quarantining any new fish before adding them to your tank can also help prevent the spread of disease.

Personally, I once had a pearl scale goldfish that developed fin rot. I noticed that its fins were torn and it was having trouble swimming.

I immediately started treatment and was able to nurse my fish back to health. It’s important to pay attention to your fish’s behavior and take action if you notice any symptoms of disease.

Signs of a Healthy Pearlscale Goldfish

If you’re a pearlscale goldfish owner, it’s important to keep an eye on your fish’s health. Here are some signs that your pearlscale goldfish is healthy:

  • Bright and Clear Eyes: The eyes of a healthy pearlscale goldfish should be bright, clear, and free of any cloudiness or discharge.
  • Active Swimming: A healthy pearlscale goldfish should be active and swim around the tank regularly.
  • Healthy Fins: The fins of a healthy pearlscale goldfish should be intact and not torn or frayed.
  • Good Appetite: A healthy pearlscale goldfish should have a good appetite and eagerly eat their food.
  • Clean and Clear Skin: The skin of a healthy pearlscale goldfish should be clean, clear, and free of any discoloration or spots.

It’s important to note that even if your pearlscale goldfish displays all of these signs, it’s still important to keep up with regular tank maintenance and water changes to ensure their continued health.

Personally, I’ve found that my pearlscale goldfish tends to be more active and playful when I provide them with a varied diet of both pellets and live or frozen food.

Additionally, adding plants to their tank not only provides them with a more natural environment but also helps keep their water clean and healthy.

Signs Your Pearlscale Goldfish Is Sick

If you’re a pearl scale goldfish owner, it’s important to be able to recognize when your fish is sick. Here are a few signs to watch out for:

Firstly, if your fish is swimming erratically or struggling to maintain its balance, it could be a sign of swim bladder disease.

This can be caused by overfeeding, constipation, or poor water quality. If you notice this behavior, it’s important to address the underlying issue as soon as possible.

Secondly, if your fish is gasping at the surface of the water, it could be a sign of low oxygen levels. This can be caused by poor water quality or a lack of aeration. Make sure to keep your tank clean and well-aerated to prevent this issue.

Thirdly, if your fish has white spots or a fuzzy growth on its body, it could be a sign of a fungal or bacterial infection. This can be caused by poor water quality or a weakened immune system. If you notice these symptoms, it’s important to quarantine your fish and treat it with the appropriate medication.

Lastly, if your fish is lethargic, not eating, or hiding for long periods of time, it could be a sign of a more serious illness. It’s important to monitor your fish closely and seek veterinary care if necessary.

Remember, the best way to keep your pearl scale goldfish healthy is to provide it with a clean and well-maintained environment. Regular water changes, a balanced diet, and proper filtration can go a long way in preventing illness and keeping your fish happy and thriving.

Personally, I once had a pearl scale goldfish that started swimming erratically and struggling to maintain balance. I immediately checked the water quality and found that the ammonia levels were high.

I did a water change and added some beneficial bacteria to the tank, and my fish made a full recovery. It’s important to be vigilant and address any issues as soon as possible to ensure the health and wellbeing of your fish.

Breeding Setup

Before breeding pearl scale goldfish, you need to set up a breeding tank. The size of the tank should be at least 20 gallons, and it should be equipped with a sponge filter to provide gentle filtration.

You should also add some spawning mops or plants to provide a surface for the fish to lay their eggs. The water temperature should be between 68-74°F, and the pH should be around 7.0-7.5.

How To Breed

To breed pearl scale goldfish, you need to select a male and a female fish. The male fish will chase the female fish around the tank, and eventually, they will spawn.

The female fish will lay eggs on the spawning mop or plants, and the male fish will fertilize them. Once the eggs are fertilized, they will hatch in 3-5 days, depending on the water temperature.

After the eggs hatch, you should remove the spawning mop or plants from the tank and transfer the fry to a separate tank. The fry should be fed with infusoria or newly hatched brine shrimp for the first few days, and then you can start feeding them with crushed flakes or pellets.


When breeding pearl scale goldfish, it’s important to provide them with proper care. You should keep the water clean by performing regular water changes, and you should also monitor the water parameters to ensure they are within the proper range. You should also feed the fish a balanced diet, consisting of both flakes and live or frozen foods.

Additionally, it’s important to keep an eye on the fry and make sure they are growing and developing properly. You should also separate the fry by size to prevent larger ones from eating smaller ones.

Personally, I find breeding pearl scale goldfish to be a rewarding experience. It’s amazing to watch the fish spawn and see the fry grow and develop into beautiful adult fish. With the right setup and care, you can successfully breed pearl scale goldfish and enjoy the process of watching them grow.
