If you’re a fan of goldfish, you may have heard of the Ryukin goldfish. This beautiful fish is known for its distinctive appearance, with a hump on its back and a long, flowing tail. But caring for a Ryukin goldfish requires a little extra attention and effort compared to other types of goldfish. In this article, we’ll cover everything you need to know about Ryukin goldfish care, so you can keep your fish healthy and happy.
Ryukin 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.

Species Summary
If you’re considering getting a Ryukin goldfish, it’s important to know as much as possible about this species before making a decision. Here’s everything you need to know about Ryukin goldfish care.
Origin
The Ryukin goldfish is a type of fancy goldfish that originated in Japan. It was first bred in the late 18th century by Japanese fish breeders who were looking to create a more ornamental fish than the common goldfish.
Today, Ryukin goldfish are popular all over the world and come in a variety of colors and patterns.
Lifespan
Ryukin goldfish can live for up to 15 years or more with proper care. However, their lifespan can be significantly shorter if they are not given the right conditions and care.
Appearance
The Ryukin goldfish has a distinctive body shape, with a pointed head and a deep, rounded body.
They have long, flowing fins and come in a variety of colors, including red, orange, white, and black. They also have a metallic sheen to their scales that gives them a beautiful, shimmering appearance.
Size
Ryukin goldfish can grow up to 8 inches in length, making them one of the larger types of fancy goldfish. It’s important to keep this in mind when choosing a tank size for your Ryukin goldfish.
Growth Rate
The growth rate of Ryukin goldfish can vary depending on several factors, including water quality, diet, and tank size. However, on average, Ryukin goldfish can grow up to 1 inch per year.
Behavior & Temperament
Ryukin goldfish are generally peaceful and social fish that do well in groups. They are active swimmers and enjoy exploring their surroundings.
However, they can be prone to bullying other fish if they are kept with smaller or slower-moving species.
Male vs Female
It can be difficult to tell the difference between male and female Ryukin goldfish, especially when they are young.
However, as they mature, males may develop small white spots on their gill covers and pectoral fins, while females may have a rounder belly and a wider anal fin.
Overall, Ryukin goldfish are a beautiful and fascinating species that can make a great addition to your aquarium. With the right care and attention, they can live a long and healthy life.
Personally, I have always been fascinated by the unique appearance of Ryukin goldfish. Their metallic scales and flowing fins make them a stunning addition to any aquarium.
However, I have also learned that they require a lot of care and attention to thrive. It’s important to provide them with a spacious tank, clean water, and a varied diet to ensure their health and well-being.
Tank Setup
Setting up the perfect tank for your ryukin goldfish is essential to their health and happiness. Here are the key factors to consider:
Tank size
The size of your tank is crucial for the well-being of your ryukin goldfish. As a general rule, you should allow 20 gallons of water per fish.
So, for example, if you have two ryukin goldfish, you should have a minimum of 40 gallons of water in your tank. A larger tank will provide more space for your fish to swim and reduce the risk of overcrowding.
Lighting
Lighting is important for both the health of your fish and the growth of any live plants in your tank.
You should aim for 8-12 hours of light per day, but make sure to provide some shaded areas for your fish to rest. Avoid direct sunlight, as this can cause temperature fluctuations and encourage algae growth.
Filtration & Aeration
A good filtration system is essential for maintaining a healthy environment for your ryukin goldfish. You should aim to filter the entire volume of your tank at least 3-5 times per hour.
In addition to filtration, you should also provide adequate aeration to ensure there is enough oxygen in the water.
Heater
Ryukin goldfish prefer water temperatures between 65-75°F, so a heater may be necessary to maintain a consistent temperature.
Make sure to choose a heater that is appropriate for the size of your tank and that has a built-in thermostat to prevent overheating.
Substrate
The substrate you choose for your tank can affect the health of your fish and the growth of any live plants.
Gravel or sand are good options, but make sure to avoid sharp or rough substrates that can damage your fish’s delicate fins.
Decoration
Add some decoration to your tank to create a stimulating environment for your ryukin goldfish. Avoid sharp or pointed objects that can harm your fish, and make sure to leave plenty of open swimming space.
Plants
Live plants can provide oxygen and help maintain water quality in your tank. Choose plants that are compatible with your ryukin goldfish and that can tolerate the temperature and lighting conditions in your tank.
By following these guidelines, you can create a comfortable and healthy environment for your ryukin goldfish to thrive in.
Water Quality
Keeping the water clean and healthy is crucial for the well-being of your Ryukin goldfish. In this section, we will discuss the key factors to consider when it comes to water quality.
Water Temperature
The ideal water temperature for Ryukin goldfish is between 65-75°F (18-24°C). It’s important to maintain a consistent temperature as sudden changes can stress your fish and make them more susceptible to diseases.
If the water temperature is too high, you can use a fan to cool it down or add ice cubes to the tank. If it’s too low, you can use a heater to warm it up.
Water pH
The optimal pH range for Ryukin goldfish is between 7.0-7.8. You can use a pH testing kit to monitor the water pH level regularly.
If the pH level is too high or too low, you can adjust it by adding pH up or pH down solutions respectively. However, sudden changes in pH can be harmful to your fish, so it’s important to make gradual adjustments.
Water Hardness
Ryukin goldfish prefer slightly hard water with a range of 100-250 ppm. You can test the water hardness level using a water hardness test kit.
If the water is too soft, you can add calcium carbonate or crushed coral to the tank to increase the hardness. If it’s too hard, you can dilute it with distilled water.
Water Changes
Regular water changes are essential for maintaining good water quality. You should aim to change 20-30% of the water every week.
This will help remove any excess waste, uneaten food, and other debris that can pollute the water. When doing water changes, make sure to use a water conditioner to remove any chlorine or chloramines in the tap water.
Personally, I find that keeping a consistent water change schedule helps me stay on top of my Ryukin goldfish care.
I usually do my water changes on Sundays, which gives me a routine to follow and ensures that my fish always have clean water. Remember, a healthy environment leads to healthy fish!
Tank Maintenance
Maintaining a clean and healthy tank is crucial for the well-being of your Ryukin Goldfish. Here are some tips to ensure proper tank maintenance:
First, make sure to regularly change the water in your tank. You should change at least 25% of the water every week to keep the water clean and clear.
I personally use a siphon to remove debris and uneaten food from the bottom of the tank before adding new water.
Second, check the pH levels of your tank regularly. Ryukin Goldfish prefer a pH level between 6.5 and 7.5. If the pH level is too high or too low, it can cause stress and health problems for your fish. You can use a testing kit to check the pH levels and adjust as necessary.
Third, clean the filter in your tank at least once a month.
A dirty filter can lead to poor water quality and harm your fish. I usually rinse the filter in a bucket of aquarium water to avoid killing the beneficial bacteria that live in the filter.
Finally, keep an eye on the temperature of your tank. Ryukin Goldfish prefer a temperature between 65 and 75 degrees Fahrenheit. Use a thermometer to monitor the temperature and adjust the heater as necessary.
By following these simple tips, you can ensure that your Ryukin Goldfish has a clean and healthy environment to thrive in.
Tank Mates
When it comes to keeping Ryukin Goldfish, choosing the right tank mates is crucial for their health and happiness. Here are some things to consider:
Compatible Fish Species
There are several species of fish that can live peacefully with Ryukin Goldfish. Some of the best options include:
- White Cloud Mountain Minnows
- Zebra Danios
- Otocinclus Catfish
- Bristlenose Plecos
These fish are all relatively small and peaceful, and they won’t compete with Ryukin Goldfish for food or space. They also have similar water requirements, which makes them great tank mates.
Incompatible Fish Species
While there are many fish that can live peacefully with Ryukin Goldfish, there are also some species that should be avoided. These include:
- Cichlids
- Tetras
- Barbs
- Guppies
These fish can be aggressive and may nip at the fins of Ryukin Goldfish. They also have different water requirements, which can make it difficult to keep them together in the same tank.
Can Ryukin Goldfish Live with Common Goldfish?
Yes, Ryukin Goldfish can live with Common Goldfish. However, it’s important to keep in mind that Common Goldfish can grow much larger than Ryukin Goldfish, which means they may require a larger tank. Additionally, Common Goldfish are more active and may outcompete Ryukin Goldfish for food.
Personal Anecdote: When I first got my Ryukin Goldfish, I made the mistake of adding some Tetras to the tank. Unfortunately, the Tetras turned out to be aggressive and started nipping at my Ryukin’s fins.
I quickly realized my mistake and removed the Tetras from the tank. Since then, I’ve had much better luck with peaceful tank mates like Bristlenose Plecos and White Cloud Mountain Minnows.
Diet
What To Feed
To keep your Ryukin Goldfish healthy, you should feed them a balanced diet that includes a mix of protein, vegetables, and carbohydrates.
You can feed them commercial flakes or pellets, but you should also supplement their diet with fresh or frozen foods such as brine shrimp, bloodworms, and peas.
Frequency
You should feed your Ryukin Goldfish small amounts of food several times a day instead of one large meal. This will help prevent overeating and reduce the risk of digestive problems.
A good rule of thumb is to feed them an amount of food that they can consume within two minutes.
Tips
It’s important to avoid overfeeding your Ryukin Goldfish, as this can lead to health problems such as swim bladder disease. You should also avoid feeding them too much protein, as this can cause digestive problems.
Additionally, make sure to remove any uneaten food from the tank after feeding to prevent it from polluting the water.
I personally like to feed my Ryukin Goldfish a mix of commercial flakes and frozen bloodworms. They seem to really enjoy the bloodworms, and it’s fun to watch them chase after the food.
Just remember to feed them in moderation and keep their tank clean to ensure their health and happiness.

- Lethargy: If your fish seems to be spending more time at the bottom of the tank or is less active than usual, it may be a sign that something is wrong.
- Abnormal swimming behavior: If your goldfish is swimming erratically, swimming upside down, or has difficulty swimming, it may be a sign of a swim bladder disorder.
- Discoloration: If your goldfish’s color changes or it develops spots or sores, it could be a sign of a bacterial or fungal infection.
If you notice any of these symptoms, it’s important to take action quickly to help your fish recover.
You can start by checking the water quality in your tank and making sure it’s within the appropriate range for your goldfish.
You may also want to consider isolating your sick fish in a separate tank to prevent the spread of any potential infections.
Personally, I had a Ryukin goldfish that suddenly became lethargic and stopped eating. I quickly realized that the water quality in my tank was poor, and I took immediate action to clean the tank and improve the water conditions.
Within a few days, my fish was back to its normal, active self. Remember, prevention is key when it comes to keeping your goldfish healthy, so make sure to maintain a clean and healthy environment for your fish.
Breeding Ryukin Goldfish
If you’re interested in breeding Ryukin goldfish, it’s important to have a good understanding of their needs and behaviors.
In this section, we’ll cover everything you need to know about breeding Ryukin goldfish, including how to set up a breeding tank, the breeding process, and care for the fry.
Breeding Setup
The first step in breeding Ryukin goldfish is to set up a breeding tank. This tank should be at least 20 gallons in size and have a filter and heater to maintain a stable water temperature and keep the water clean.
You should also provide plenty of hiding places for the fish, such as plants or rocks, to help reduce stress and aggression during the breeding process.
When selecting your breeding pair, it’s important to choose healthy and compatible fish. Look for fish with bright colors, clear eyes, and no signs of disease.
You should also choose fish that are similar in size and temperament to help reduce aggression during breeding.
How To Breed
Ryukin goldfish are egg layers, meaning that the female will lay eggs and the male will fertilize them.
To encourage breeding, you should gradually increase the water temperature in the breeding tank to around 75-80°F. You should also provide a spawning mop or other breeding surface for the fish to lay their eggs on.
Once the female has laid her eggs, the male will fertilize them. You should remove the parents from the breeding tank once spawning is complete to prevent them from eating the eggs or fry.
Care
After the eggs have been fertilized, they will hatch in 3-5 days. The fry will initially feed on their egg sacs, but you should start feeding them small amounts of crushed flake food or baby brine shrimp once they become free-swimming.
It’s important to keep the water in the breeding tank clean and well-oxygenated to ensure the health of the fry.
You should perform regular water changes and monitor the water parameters closely. As the fry grow, you may need to separate them into a larger tank to prevent overcrowding and ensure their continued health and growth.
I have found that breeding Ryukin goldfish can be a rewarding and enjoyable experience. With the proper setup, care, and attention, you can successfully breed and raise healthy and beautiful Ryukin goldfish fry.
