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

If you’re a fish enthusiast, you might have heard of the Celestial eye goldfish. This unique breed of goldfish is known for its protruding eyes that point upwards towards the sky, giving it its name. But caring for these fish is a bit different than caring for other goldfish breeds. In this article, we’ll cover everything you need to know about Celestial eye goldfish care, from their diet to their tank requirements and more.

Celestial Eye Goldfish is a fancy variety of goldfish that requires a minimum tank size of 20 gallons. They prefer a pH range of 6.5-7.5 and moderate water flow. They are omnivorous and should be fed a varied diet of flakes, pellets, and live/frozen foods. Regular water changes and proper filtration are necessary for their well-being.

First and foremost, it’s important to note that Celestial eye goldfish are delicate creatures that require a bit more attention than other goldfish breeds. They’re prone to swim bladder issues, which can be caused by overfeeding or a poor diet. It’s crucial to feed them a balanced diet of high-quality pellets, vegetables, and occasional treats like bloodworms.

When it comes to their tank requirements, Celestial eye goldfish thrive in spacious tanks with ample room to swim around. They also prefer cooler water temperatures, so it’s important to keep the tank between 65-72°F. Additionally, these fish are sensitive to high levels of ammonia and nitrites, so it’s crucial to maintain a clean tank with regular water changes.

Tank Setup

Setting up a tank for your Celestial Eye Goldfish is an essential step in providing them with a comfortable and healthy living environment.

Below are some key considerations for setting up your tank:

Tank Size

When it comes to tank size for Celestial Eye Goldfish, the general rule of thumb is to provide at least 20 gallons of water per fish.

This ensures that your goldfish have enough space to swim around and reduces the risk of overcrowding.

Keep in mind that these fish are prone to swim bladder issues, so a deep tank with minimal height is ideal.


Celestial Eye Goldfish do not require any special lighting requirements.

However, it is recommended to provide a light source that mimics natural daylight to promote a healthy day and night cycle.

A timer can be used to ensure consistent lighting times.

Filtration & Aeration

Proper filtration and aeration are crucial for maintaining a healthy environment for your Celestial Eye Goldfish.

A good filtration system will help remove waste and toxins from the water, while aeration will provide oxygen for your fish.

A combination of a hang-on-back filter and an air pump with an air stone is recommended.


Celestial Eye Goldfish are cold-water fish and can tolerate temperatures between 65-75°F.

It is recommended to use a heater to maintain a consistent temperature in the tank, especially during colder months.


When choosing a substrate for your tank, it is important to select one that is safe for your fish.

Avoid using sharp or rough substrates that can damage their delicate fins. Fine sand or smooth gravel are good options.


Adding decorations to your tank can provide a stimulating and visually appealing environment for your Celestial Eye Goldfish.

However, it is important to avoid sharp or rough decorations that can cause injury. Smooth rocks, driftwood, and ceramic decorations are safe options.


Live plants can provide additional benefits to your tank, such as oxygenation and natural filtration.

It is important to choose plants that are safe for your fish and can tolerate the temperature and pH of your tank. Some good options include Java Fern, Anubias, and Hornwort.

When setting up your tank, it is important to keep in mind the needs and preferences of your Celestial Eye Goldfish.

With proper care and attention to their environment, your goldfish can thrive and live a happy and healthy life.

Personal Anecdote: When I first set up my Celestial Eye Goldfish tank, I made the mistake of using a rough substrate that ended up damaging their delicate fins. After switching to a smooth gravel, I noticed a significant improvement in their overall health and happiness.

Water Quality

Keeping the water clean and healthy is crucial to the well-being of your celestial eye goldfish. Here are some things you need to know about maintaining water quality:

Water Temperature

The ideal water temperature for celestial eye goldfish is between 65 and 72 degrees Fahrenheit. You can use a thermometer to check the temperature of the water.

If the water is too cold, your fish will become sluggish and may stop eating. If it’s too warm, your fish may become stressed and more susceptible to diseases.

Water pH

The pH level of the water should be between 7.0 and 8.4. If the pH level is too low, it can cause stress and health problems for your fish.

If it’s too high, it can lead to algae growth and other water quality issues. You can use a pH test kit to check the pH level of your water.

Water Hardness

The ideal water hardness for celestial eye goldfish is between 150 and 300 ppm (parts per million). If the water is too soft, it can cause stress and health problems for your fish.

If it’s too hard, it can lead to mineral buildup and other water quality issues. You can use a water hardness test kit to check the hardness of your water.

Water Changes

It’s important to change the water in your tank regularly to maintain good water quality. You should aim to change about 25% of the water in your tank every week.

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

Personally, I find that doing water changes on a regular schedule helps me remember to keep up with this important task. I like to do my water changes every Sunday morning before I start my day. It’s become a routine for me and my fish have been healthy and happy as a result.

Tank Maintenance

Keeping your Celestial eye goldfish healthy and happy requires proper tank maintenance. Here are a few tips to help you keep your tank clean and your fish thriving:

First, make sure to change out 10-20% of the water in your tank every week. This helps to remove any excess waste and debris that can build up over time.

When doing a water change, be sure to use a water conditioner to remove any harmful chemicals or toxins that may be present in your tap water.

Second, clean your tank regularly. This includes wiping down the glass, removing any excess food or waste, and cleaning your filter. A dirty tank can lead to poor water quality, which can be harmful to your fish.

Third, keep an eye on the temperature of your tank. Celestial eye goldfish prefer cooler water, so make sure the temperature stays between 65-72°F. If the water gets too warm, it can lead to stress and illness in your fish.

Finally, consider adding live plants to your tank. Not only do they help to oxygenate the water, but they also provide a natural source of filtration.

Plus, they add a beautiful touch to your tank! I personally love adding some java moss to my tank for a pop of greenery.

By following these tips, you can ensure that your Celestial eye goldfish have a clean and healthy environment to thrive in.

Tank Mates

If you’re thinking about adding some tank mates for your Celestial eye goldfish, it’s important to choose carefully. Here are some things to consider:

Compatible Fish Species

There are several species of fish that can live peacefully with Celestial eye goldfish. Some good options include:

  • White Cloud Mountain Minnows
  • Zebra Danios
  • Bristlenose Plecos
  • Otocinclus Catfish

These fish are all peaceful and won’t compete with your Celestial eye goldfish for food or territory. Plus, they all have similar water temperature and pH requirements.

Incompatible Fish Species

On the other hand, there are some fish species that are not recommended to be kept with Celestial eye goldfish. These include:

  • Angelfish
  • Tetras
  • Guppies
  • Barbs

These fish can be aggressive or have different temperature or pH requirements than Celestial eye goldfish, which can cause stress and health problems.

It’s important to keep in mind that Celestial eye goldfish are social creatures and should not be kept alone.

You should have at least two Celestial eye goldfish in your tank, but ideally, you should have three or more. This will help them feel more comfortable and reduce stress.

Personally, I have found that my Celestial eye goldfish are happiest when they have a group of four or five friends swimming around with them. They seem to be more active and playful when they have company!


Proper diet is crucial for the health and well-being of your Celestial eye goldfish. In this section, we will discuss what to feed your goldfish, how often to feed them, and some tips to keep in mind.

What To Feed

When it comes to feeding your Celestial eye goldfish, there are a few options to choose from. You can feed them commercial fish food, live food, or a combination of both.

Personally, I prefer to feed my goldfish a mix of commercial fish food and live food. I find that this provides them with a well-rounded diet and keeps them healthy and happy.

Commercial fish food is readily available at most pet stores and comes in various forms such as flakes, pellets, and freeze-dried options.

Look for a high-quality fish food that contains a good balance of protein, vitamins, and minerals.

Live food options include brine shrimp, bloodworms, and daphnia. These can be purchased at pet stores or even bred at home.

Live food is a great way to provide your goldfish with a more natural diet and can also help stimulate their appetite.


It is important to feed your Celestial eye goldfish the right amount of food and at the right frequency. Overfeeding can lead to health problems such as obesity and swim bladder issues.

As a general rule of thumb, feed your goldfish a small amount of food 2-3 times a day. The amount of food should be enough to be consumed within 2-3 minutes.

If there is any uneaten food after this time, remove it from the tank to prevent it from fouling the water.


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

  • Offer a variety of food to keep their diet interesting and balanced
  • Avoid overfeeding by following the 2-3 minute rule
  • Remove any uneaten food to prevent water quality issues
  • Consider using a feeding ring to keep the food in one place and prevent it from floating around the tank
  • Monitor your goldfish’s weight and adjust their diet accordingly

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

Common Diseases


Celestial eye goldfish are prone to several diseases that can affect their health and well-being. Some of the most common diseases include bacterial infections, fungal infections, and parasitic infections.


If your celestial eye goldfish is sick, you may notice several symptoms. These can include lethargy, loss of appetite, abnormal swimming behavior, discoloration, and visible signs of infection such as ulcers or lesions.


If you notice any of these symptoms, it’s important to take action quickly. In some cases, you may be able to treat the disease at home with over-the-counter medications.

However, if the symptoms persist or worsen, it’s important to consult with a veterinarian who specializes in fish health.


The best way to prevent diseases in your celestial eye goldfish is to maintain a clean and healthy environment. This includes regular water changes, proper filtration, and a balanced diet.

Additionally, it’s important to quarantine any new fish before adding them to your tank to prevent the spread of disease. I remember when I first got my celestial eye goldfish, I didn’t know much about fish care.

Unfortunately, my lack of knowledge led to my fish becoming sick with a bacterial infection. It was a scary experience, but with the help of a veterinarian, I was able to nurse my fish back to health.

Since then, I’ve learned the importance of proper fish care and the role it plays in preventing diseases.

Signs of a Healthy Celestial Eye Goldfish

When it comes to caring for your Celestial eye goldfish, it’s essential to know how to spot a healthy fish. Here are some signs to look out for:

  1. Bright and Clear Eyes: One of the most noticeable signs of a healthy Celestial eye goldfish is bright, clear eyes. If your fish’s eyes are cloudy or dull, it may be a sign of poor health.
  2. Active and Alert: Healthy fish are active and alert, swimming around their tank and exploring their surroundings. If your fish seems lethargic or spends most of its time at the bottom of the tank, it may be a sign of illness.
  3. Healthy Appetite: A healthy Celestial eye goldfish will have a healthy appetite and eagerly eat its food. If your fish is not eating or seems uninterested in food, it may be a sign of illness.
  4. Clear and Vibrant Scales: Another sign of a healthy fish is clear and vibrant scales. If your fish’s scales are dull or discolored, it may be a sign of poor health.
  5. Good Fins: Healthy fish have good fins that are not torn or damaged. If your fish’s fins are frayed or torn, it may be a sign of illness or poor water quality.
  6. Normal Breathing: Healthy fish breathe normally and do not gasp for air at the surface of the water. If your fish seems to be struggling to breathe, it may be a sign of poor water quality or illness.

Remember, keeping your Celestial eye goldfish healthy requires proper care and attention.

By monitoring your fish’s behavior and appearance, you can catch any potential health problems early and ensure that your fish thrives in its environment.

Personally, I always keep a close eye on my fish and make sure to check for any signs of illness or poor health. It’s important to me that my fish are happy and healthy, and I take pride in providing them with the best possible care.

Signs Your Celestial Eye Goldfish Is Sick

If you are a proud owner of a Celestial eye goldfish, it is essential to keep an eye on their health. Here are some signs to look out for that indicate your fish may be unwell:

  1. Loss of appetite: If your fish is not eating, it may be a sign of illness.
  2. Abnormal swimming behavior: If your fish is swimming erratically or struggling to swim, it may be a sign of a swim bladder issue or another health problem.
  3. Changes in appearance: If your fish is losing color or has visible sores or lesions, it may be a sign of a bacterial or fungal infection.
  4. 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 gill problem.

If you notice any of these signs, it is essential to take action immediately.

You can start by checking the water quality and making sure the temperature is within the recommended range.

You may also want to consult a veterinarian who specializes in fish care.

I once had a Celestial eye goldfish that stopped eating and became lethargic. I did some research and discovered that it was suffering from swim bladder disease.

I immediately took action to adjust the water temperature and added some Epsom salt to the tank. Within a few days, my fish was back to its active and healthy self.

It is essential to pay close attention to your fish’s behavior and take action promptly to keep them healthy and happy.


Breeding Setup

Breeding Celestial eye goldfish is a fun and rewarding experience. However, it requires a bit of preparation and a suitable breeding setup.

You will need a separate tank for breeding, which should be at least 20 gallons in size. The tank should have a filtration system, a heater, and an air pump.

You will also need a spawning mop or plants for the goldfish to lay their eggs on.

How To Breed

Breeding Celestial eye goldfish is relatively easy. Once you have set up the breeding tank, introduce a male and a female goldfish to the tank.

The male will start chasing the female around the tank, trying to nudge her towards the spawning mop or plants.

Once the female is ready to lay her eggs, she will lay them on the spawning mop or plants. After the female has laid her eggs, remove the adult goldfish from the breeding tank.

The eggs will hatch in about 4-5 days, and the fry will start swimming around the tank. You can feed them with infusoria or commercially available fry food.


Once the fry have hatched, it is important to take good care of them. Keep the water clean and well-aerated, and feed them small amounts of food several times a day.

As they grow, you can gradually increase the amount and frequency of their feedings. It is also important to monitor the water temperature and pH levels to ensure that they are within the appropriate range for the fry.

Keep an eye out for any signs of illness or disease, and treat them promptly if necessary. I remember the first time I bred Celestial eye goldfish.

It was a rewarding experience, and I was excited to see the fry hatch and grow. With the right setup and care, you too can enjoy the experience of breeding these beautiful fish.
