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

If you’re considering adding a new fish to your aquarium, an Oranda goldfish is a great choice. These fish are known for their unique appearance, including their round bodies and protruding heads, and they come in a variety of colors. However, caring for an Oranda goldfish requires some specific knowledge and attention to detail. In this article, we’ll cover everything you need to know to give your Oranda goldfish the best possible care.

Oranda 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.

One of the most important aspects of Oranda goldfish care is providing the right environment for your fish.

These fish require a tank that is at least 20 gallons in size, with a filter that can handle the waste produced by your fish.

You’ll also need to maintain the water temperature and pH levels within a specific range to keep your fish healthy.

Additionally, Oranda goldfish can be sensitive to water quality, so regular water changes and tank maintenance are essential.

Feeding your Oranda goldfish is another crucial aspect of care. These fish have a tendency to overeat, which can lead to health problems such as swim bladder disease.

You’ll need to feed your Oranda goldfish a balanced diet of high-quality pellets or flakes, and avoid overfeeding. It’s also important to be aware of any signs of illness or disease, such as changes in behavior or appearance, and take action promptly if you notice any issues.

Species Summary


Oranda goldfish are a type of fancy goldfish that originated in China.

They were first bred during the Ming Dynasty and were highly prized for their unique appearance.


Oranda goldfish have a lifespan of 10-15 years if they are properly cared for.

With good water quality, a healthy diet, and a suitable environment, your oranda can live a long and happy life.


Oranda goldfish are known for their distinctive “wen,” or head growth, which resembles a raspberry or hood. Their scales are metallic and come in a variety of colors, including red, orange, yellow, black, and white.


Oranda goldfish can grow up to 8 inches in length, but their size will depend on their environment and diet.

A larger tank and a varied diet will help your oranda reach its full potential.

Growth Rate

Oranda goldfish have a moderate growth rate, which means they will not grow as quickly as some other types of goldfish.

It’s important to monitor their growth and adjust their diet and environment accordingly.

Behavior & Temperament

Oranda goldfish are generally peaceful and get along well with other goldfish. They are active swimmers and enjoy exploring their environment.

However, they can be easily startled, so it’s important to provide them with plenty of hiding places.

Male vs Female

It can be difficult to distinguish between male and female oranda goldfish, as they do not have any external differences. The only way to tell for sure is to observe their behavior during breeding season.

I remember when I first got my oranda goldfish. I was amazed by its unique appearance and quickly fell in love with its playful personality.

With proper care and attention, your oranda can bring you years of joy and companionship.

Tank Setup

Tank Size

The first thing you need to consider when setting up a tank for your Oranda goldfish is the tank size. These fish can grow up to 8 inches long, so you’ll need a tank that can accommodate their size.

A good rule of thumb is to have at least 20 gallons of water per fish. So, for one Oranda goldfish, you’ll need a 20-gallon tank. If you plan on having more than one fish, you’ll need a larger tank.


Lighting is also important when setting up a tank for Oranda goldfish. These fish prefer low to moderate lighting, so avoid bright lights that can stress them out.

You can use a timer to ensure that the tank gets 10-12 hours of light per day.

Filtration & Aeration

Filtration and aeration are crucial for maintaining a healthy environment for your Oranda goldfish.

A good filter will remove waste and debris from the water, while aeration will add oxygen to the water. You can use a hang-on-back filter or a canister filter, and an air stone or bubble wand for aeration.


Oranda goldfish are cold-water fish and can tolerate a wide range of temperatures. However, it’s important to maintain a consistent temperature in the tank.

A heater can help you do this. Set the heater to a temperature between 68-74°F.


The substrate you choose for your Oranda goldfish tank is important. These fish like to dig and sift through the substrate, so avoid sharp or rough substrates that can injure them.

Sand or smooth gravel are good options.


Adding decorations to your Oranda goldfish tank can make it more visually appealing.

Be sure to choose decorations that are safe for your fish. Avoid decorations with sharp edges or small parts that can be swallowed.


Live plants can help maintain a healthy environment for your Oranda goldfish. They provide oxygen and absorb waste products. Choose plants that are easy to care for, such as Java fern or Anubias.

Be sure to quarantine new plants before adding them to the tank to prevent the introduction of diseases. Setting up a tank for your Oranda goldfish requires some thought and planning.

By considering the tank size, lighting, filtration and aeration, heater, substrate, decoration, and plants, you can create a healthy and comfortable environment for your fish to thrive in.

I remember when I first set up my Oranda goldfish tank, I made sure to research and consider all of these factors to ensure that my fish were happy and healthy.

Water Quality

Water quality is an essential factor in maintaining the health and well-being of your Oranda goldfish. Poor water quality can lead to stress, illness, and even death.

In this section, we will discuss the different aspects of water quality that you need to be aware of.

Water Temperature

The ideal water temperature for Oranda goldfish is between 68-74°F (20-23°C). Any temperature above or below this range can cause stress and health problems for your fish.

You can use a thermometer to monitor the water temperature and adjust it as needed. Avoid sudden temperature changes, as they can be harmful to your fish.

Water pH

The optimal pH range for Oranda goldfish is between 7.0-7.8. It is important to maintain a stable pH level, as fluctuations can cause stress and harm to your fish.

You can use a pH testing kit to monitor the pH level of your water. If the pH level is too high or too low, you can adjust it by adding pH adjusters to your water.

Water Hardness

Oranda goldfish prefer moderately hard water with a range of 150-300 ppm. You can test the hardness of your water using a water hardness testing kit.

If the water is too soft or too hard, you can adjust it by adding minerals or using a water softener.

Water Changes

Regular water changes are crucial for maintaining good water quality. You should change 20-30% of the water in your tank every week.

This will help remove excess waste and harmful chemicals from the water. When changing the water, make sure to use a water conditioner to remove chlorine and other harmful chemicals from the tap water.

When it comes to water quality, prevention is key.

By maintaining the proper water temperature, pH level, hardness, and performing regular water changes, you can ensure that your Oranda goldfish will thrive in a healthy and happy environment.

Personally, I have found that maintaining good water quality is one of the most important aspects of Oranda goldfish care.

By sticking to a regular water change schedule and monitoring the water temperature, pH, and hardness, I have been able to keep my fish healthy and happy for years.

Tank Maintenance

Maintaining a clean and healthy tank for your Oranda Goldfish is crucial for their overall health and well-being. Here are a few tips to keep in mind:

First, make sure to perform regular water changes. This will help remove any excess waste and debris that can accumulate in the tank. A good rule of thumb is to change 25% of the water every week.

Secondly, it’s important to keep the tank clean. This means regularly cleaning the gravel and any decorations in the tank. You can use a siphon to vacuum the gravel and a soft-bristled brush to clean any decorations.

Thirdly, monitor the water temperature and pH levels regularly. Oranda Goldfish prefer a water temperature between 65-72°F and a pH level between 7.0-8.4. You can use a thermometer and pH test kit to keep track of these levels.

Finally, make sure to check your tank’s filtration system regularly. Filters can become clogged with debris and waste, which can affect the water quality.

Clean or replace the filter as needed to keep the tank clean and healthy for your Oranda Goldfish.

Personally, I have found that keeping a regular maintenance schedule for my Oranda Goldfish tank has helped keep my fish healthy and happy. By following these simple steps, you can ensure that your Oranda Goldfish thrive in their environment.

Tank Mates

When it comes to Oranda goldfish care, choosing the right tank mates is crucial for the health and happiness of your fish. Here are some things to keep in mind when selecting compatible fish species:

Compatible Fish Species

Oranda goldfish are social creatures and enjoy the company of other peaceful fish. Good tank mates for Oranda goldfish include:

  • Other types of goldfish, such as Ryukin and Fantail
  • White Cloud Mountain Minnows
  • Corydoras Catfish
  • Otocinclus Catfish
  • Mystery Snails

Incompatible Fish Species

Some fish species are not compatible with Oranda goldfish and should be avoided. These include:

  • Tropical fish that require warmer water temperatures
  • Territorial fish, such as Cichlids
  • Aggressive fish, such as Bettas or Gouramis

How many Oranda goldfish can live together?

When it comes to determining how many Oranda goldfish can live together, a good rule of thumb is to have 20 gallons of water for the first fish and an additional 10 gallons for each additional fish.

For example, if you have two Oranda goldfish, you should have a minimum of 30 gallons of water in your tank. This will ensure that your fish have enough space to swim and thrive.

Personally, I have found that keeping Oranda goldfish with other types of goldfish works well. They all get along and seem to enjoy each other’s company. Just be sure to choose fish that have similar water temperature and pH requirements.


Proper diet is essential to keep your Oranda goldfish healthy and happy. Here’s what you need to know about feeding your Oranda goldfish:

What To Feed

Oranda goldfish are omnivores and will eat a variety of foods. You can feed them commercial fish food, frozen or live foods, and fresh vegetables.

A good quality commercial fish food should contain all the necessary nutrients for your Oranda goldfish.

You can also supplement their diet with live or frozen foods like brine shrimp, bloodworms, and daphnia. Fresh vegetables like peas, lettuce, and spinach are also good for your Oranda goldfish.


Feed your Oranda goldfish small amounts of food two to three times a day.

Overfeeding can lead to health problems like constipation and swim bladder disease. It’s important to feed your Oranda goldfish the right amount of food to keep them healthy and happy.


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

  • Avoid feeding your Oranda goldfish too much at once. They have small stomachs and can only eat a little bit of food at a time.
  • Remove any uneaten food from the tank after feeding. This will help keep the water clean and prevent health problems.
  • Try to vary your Oranda goldfish’s diet to provide them with a variety of nutrients.

Personally, I like to feed my Oranda goldfish a mix of commercial fish food and fresh vegetables. I find that they enjoy the variety and it keeps them healthy and happy.

Common Diseases


Oranda goldfish are susceptible to various diseases. Some of the common diseases that affect oranda goldfish include:

  • Ich or White Spot Disease
  • Fin Rot
  • Dropsy
  • Swim Bladder Disorder


It is important to be aware of the symptoms of these diseases so that you can identify them early and seek treatment. Some of the common symptoms of these diseases include:

  • Ich or White Spot Disease – white spots on the body and fins

The best way to prevent these diseases is to maintain good water quality in your tank. Make sure to perform regular water changes and keep the tank clean.

You should also avoid overcrowding the tank and make sure that the fish have enough space to swim around. Additionally, it is important to feed your fish a balanced diet and avoid overfeeding.

Personally, I have had to deal with fin rot in my oranda goldfish. I noticed that the fins were frayed and disintegrating, so I immediately sought treatment and quarantined the affected fish.

After following the instructions carefully, the fish made a full recovery and I was able to reintroduce it back into the tank.

Signs of a Healthy Oranda Goldfish

When it comes to keeping Oranda Goldfish, it’s important to be able to identify the signs of a healthy fish. Here are some things to look out for:

Personally, I’ve found that keeping a close eye on my Oranda Goldfish and monitoring its behavior and appearance has been key to ensuring its health and well-being.

By following these tips and keeping a watchful eye on your fish, you can help ensure that your Oranda Goldfish stays healthy and happy for years to come.

Signs Your Oranda Goldfish is Sick

If you’re a proud owner of an Oranda goldfish, you know how important it is to keep them healthy and happy. However, even with the best care, your fish may become sick. Here are some signs to watch out for:

  1. Lethargy: If your fish is floating at the top of the tank or sitting at the bottom, it may be a sign that they’re not feeling well.
  2. Loss of Appetite: If your fish is not eating or eating less than usual, it may be a sign of illness.
  3. Erratic Swimming: If your fish is swimming erratically or struggling to swim, it may be a sign of a swim bladder problem or other health issue.
  4. Abnormal Appearance: If your fish has any unusual growths, spots, or discoloration, it may be a sign of a bacterial or fungal infection.
  5. Gasping for Air: If your fish is gasping for air at the surface of the water, it may be a sign of poor water quality or a respiratory infection.

If you notice any of these signs, it’s important to take action quickly to help your fish recover. Consult with a veterinarian who specializes in fish care or a knowledgeable pet store employee for advice on how to proceed.

Personal Anecdote: I once had an Oranda goldfish that suddenly became lethargic and stopped eating. I quickly realized that the water quality in the tank was poor, and I needed to do a water change immediately. After the water change and some careful monitoring, my fish made a full recovery.

If you’re interested in breeding Oranda goldfish, there are a few things you need to know to ensure a successful breeding process. Here are the three main sub-sections to consider:

Breeding Setup

Before breeding, you’ll need to set up a separate tank for your Oranda goldfish to breed in. The tank should be at least 20 gallons and should have a sponge filter to keep the water clean.

You’ll also need to add some plants or spawning mops for the fish to lay their eggs on. Make sure the water temperature is around 68-74°F and the pH level is between 7.0-7.4.

How To Breed

Once your breeding tank is set up, you can introduce your male and female Oranda goldfish. Make sure to feed them a high-quality diet to ensure they are healthy and ready to breed.

When the female is ready to lay her eggs, she will lay them on the plants or spawning mops. The male will then fertilize the eggs.

After the eggs are fertilized, you can remove the parents from the breeding tank to prevent them from eating the eggs.


After the eggs are fertilized, it’s important to take good care of them to ensure they hatch successfully. You can use a fungicide to prevent fungus from growing on the eggs.

The eggs will hatch in about 4-7 days, and the fry will absorb their yolk sacs for the first few days. After that, you can start feeding them small amounts of infusoria or liquid fry food.

Make sure to keep the water clean and maintain the proper temperature and pH levels.

When breeding Oranda goldfish, it’s important to be patient and take good care of your fish. Breeding can be a rewarding experience, but it does require some effort and attention to detail.

I remember when I bred my first Oranda goldfish, it was such an exciting experience to see the eggs hatch and watch the fry grow. With the right setup and care, you can have a successful breeding experience too!
