Origins and Natural Habitat

You might be curious about the roots of the unique Celestial Eye Goldfish. Native to China, they were developed from the Prussian Carp during the Ming Dynasty (1368-1644). Their distinct upward-facing eyes emerged from a mutation, and the Chinese selectively bred them to preserve this unusual trait. This breed later made its way to Japan and entered the United States in the early 20th century.

In their natural habitat, these fascinating fish find their roots in Asia, where their wild carp ancestors lived. Being ornamental fish, they do not have a specific natural habitat, but they thrive in freshwater aquariums. When setting up an aquarium for your Celestial Eye Goldfish, remember to provide them with a spacious environment and careful water maintenance to imitate their ideal living conditions.

Now that you know the origins of the Celestial Eye Goldfish, you can appreciate their rich history and rarity. With a proper care guide, these delightful fish will make a great addition to your home.

Physical Characteristics

Size and Shape

The Celestial Eye Goldfish is a round-bodied fish, typically growing to an adult size of 10-14 inches (25-36 cm). They are unique due to their lack of a dorsal fin, which makes them rather clumsy swimmers.

Color and Markings

These goldfish come in a variety of vibrant colors including orange, red, white, and combinations of these colors. Their most striking feature is their upwards-facing eyes, giving them a whimsical appearance as they gaze towards the sky.

It’s important to take the physical characteristics of Celestial Eye Goldfish into account when caring for them. Due to their unique shape and protruding eyes, they may need special considerations when setting up their tank environment and feeding. However, with proper care and attention, you can enjoy watching these friendly and intriguing fish thrive in your aquarium.

Lifespan and Growth Rate

The Celestial Eye Goldfish is known for being a relatively long-lived fancy goldfish variety. With proper care and a healthy living environment, these unique fish can live 10-15 years! That’s quite impressive compared to some other fancy goldfish breeds that have shorter lifespans.

To support your Celestial Eye Goldfish throughout their growth, provide them with a balanced diet of diverse food options. They are omnivorous by nature and appreciate a mix of flakes, pellets, live, and frozen foods. Maintaining variety in their diet not only helps ensure they receive all the necessary nutrients but also keeps their mealtimes enjoyable.

Remember that a suitable tank setup is essential for your goldfish to thrive—keep the water temperature stable, pH balanced, and change the water periodically. In their early growth stages, you might notice the Celestial Eye Goldfish growing at a faster rate than they will in the latter part of their lives. Their growth rate eventually slows down but don’t worry—this is a normal part of their development.

By focusing on proper care and providing them with a healthy habitat, you’ll help your Celestial Eye Goldfish achieve their full potential in both lifespan and growth rate, allowing them to become long-time companions in your aquatic adventures.

Diet and Feeding

Feeding your Celestial Eye Goldfish a well-balanced diet is crucial to maintaining their health and well-being. As omnivores, they enjoy various types of food, such as flakes, pellets, and live or frozen foods.

A mix of high-quality flakes and pellets should make up the primary portion of their diet. However, don’t forget to provide them with treats like brine shrimp, bloodworms, and daphnia to meet their nutritional needs. Make sure to avoid overfeeding, as this can lead to water quality issues and health problems. It is recommended to feed them small amounts, about 2-3 times a day.

To ensure your Celestial Eye Goldfish remains in good health, pay attention to the ingredients in the food you’re offering. Look for items high in protein and vitamins while avoiding low-quality fillers. If you’re introducing new food, do it gradually to avoid digestive issues.

Remember, a happy and healthy Celestial Eye Goldfish starts with a well-rounded and nutritious diet. Stay consistent with their feeding schedule, provide a variety of foods, and watch your goldfish thrive!

Behavior and Temperament

Celestial Eye Goldfish are known for their friendly and peaceful nature. As a gregarious fish, they enjoy the company of other similar goldfish as long as they aren’t aggressive. They are slow-moving animals that spend most of their waking time scavenging.

Since they have unique upward-facing eyes and lack a dorsal fin, they tend to be clumsy swimmers. Due to their limited mobility, they may require extra care and attention when it comes to their living environment. Make sure to avoid sharp objects and strong currents in the tank to keep your goldfish safe and happy.

It’s essential to provide your Celestial Eye Goldfish with enough space to swim and explore, as well as suitable hiding spots to relieve stress. A well-balanced environment with proper tank mates will contribute to their overall well-being and allow them to exhibit their natural behavior.

Keep in mind, these goldfish are not suitable for competitive environments or overcrowded tanks, as it could lead to increased stress and difficulty in competing for food. By understanding and catering to their unique temperament, you can ensure a healthy and thriving life for your Celestial Eye Goldfish.

Care and Tank Requirements

Tank Size

Ensure your celestial eye goldfish has ample space to swim. A minimum tank size of 20 gallons is recommended for one goldfish, and you should add 10 gallons for each additional fish. A spacious tank will enable them to move freely and comfortably.

Water Parameters (Temperature and pH)

Maintain a comfortable water temperature for your celestial eye goldfish, ideally between 65-72°F. To achieve stable water conditions, use a heater and a thermometer to monitor the temperature.

Maintain the pH levels between 6.0-8.0. Regularly check the water quality, as these fish are sensitive to fluctuations and can be easily stressed.

Tank Setup and Decorations

Create a pleasant environment by adding plants and decorations, but ensure they do not hinder the fishes’ movement. Since celestial eye goldfish are clumsy swimmers and lack dorsal fins, keep the decor smooth to prevent injury.

Provide a moderate layer of substrate with a preference for smooth, small gravel or sand to prevent potential harm to their eyes. You could use:

  • Smooth rocks or ceramic decorations
  • Live or silk aquatic plants
  • Smooth driftwood

Filtration and Aeration

Celestial eye goldfish are sensitive to ammonia and nitrites. A well-functioning filter helps maintain water quality by reducing these pollutants. Regularly check and clean your filter to ensure its effectiveness.

Adequate aeration is essential to preserve oxygen levels, especially during warmer periods when water temperature rises. Use an air pump and airstone to facilitate proper oxygenation and promote a healthy environment for your celestial eye goldfish.

Suitable Tank Mates

When choosing tank mates for your Celestial Eye Goldfish, it’s essential to consider their unique characteristics and potential compatibility issues. To maintain a harmonious environment, here’s a list of suitable tank mates:

  • Fantail Goldfish: These friendly and social fish have rounded bodies with a long, flowing fin, making them an excellent match for your Celestial Eye Goldfish.
  • Ryukin Goldfish: Known for their large humps and sturdy bodies, Ryukin Goldfish can live peacefully with your Celestial Eye Goldfish due to their similar size and temperament.
  • Ranchu Goldfish: With their plump bodies and interesting head growths, Ranchu Goldfish coexist well with Celestial Eye Goldfish in a community tank.

Always monitor your fish for any signs of aggression or distress and adjust tank mates if needed. Providing ample space, hiding spots, and maintaining proper water quality can also contribute to a peaceful environment for your celestial eye goldfish and their tank mates.

Remember, adapting to new tank mates may take time, so give your fish the opportunity to get acquainted with each other gradually. With the right tank mates and care, your Celestial Eye Goldfish can thrive in a happy and healthy aquatic community.

Breeding Process

Breeding Celestial Eye Goldfish can be an exciting adventure. To get started, you should first create a conducive environment to encourage breeding behavior. Set up a separate, well-planted breeding tank with plenty of hiding spots for the eggs.

Increase the water temperature in the breeding tank to around 68-74°F, as this will stimulate mating behaviors. Be sure to have a balanced male-to-female ratio, typically with one male for every two females. Observe your goldfish for signs of breeding readiness, which includes males developing white bumps called breeding tubercles on their gill covers and pectoral fins.

Once you spot these signs, start feeding your fish a protein-rich diet with live or frozen foods like brine shrimp and daphnia. This extra nutrition will provide the energy needed for breeding.

During the spawning process, males will chase the females around the tank, nudging their abdomens to encourage egg release. Females will lay sticky eggs amongst the plants, where they will be fertilized by the males. At this point, it’s crucial to remove the adult fish to prevent them from eating the eggs.

After 4-7 days, the eggs will hatch into fry, which you can feed with special fry food or crushed flakes. As the fry grow, gradually increase the food size until they can consume regular goldfish food. With proper care, your Celestial Eye Goldfish fry will soon grow into beautiful, healthy adults, and you’ll have successfully bred this unique variety.

Common Diseases and Treatments

Celestial Eye Goldfish may occasionally face health issues, but with proper care, you can ensure they remain healthy. One common disease is Dropsy. If you notice an affected fish, immediately isolate them in a separate tank and focus on maintaining perfect water quality.

Eye injuries can also occur due to their upward-facing eyes. Make sure your tank decorations don’t have sharp edges and provide ample space for swimming. In case of an injury, keep the water clean to prevent infection.

Ich is another condition that can affect your Celestial Eye Goldfish. It appears as white spots on their skin. To treat this, increase the water temperature to 86°F for a few days and use aquarium salt or over-the-counter medication specifically for Ich.

Bacterial infections may show up as red inflamed skin or ulcers. Maintain good water quality and use broad-spectrum antibiotics specifically designed for aquarium fish as a treatment.

Keep an eye out for flukes, which are small parasites that can attach to your fish. If identified, administer anti-parasite medication for aquarium fish to rid your celestial eye goldfish of these hitchhikers.

Lastly, cloudy eye can result from poor water conditions or injury. Improve water quality and consider using aquarium salt to help with healing.

Remember, prevention is the best medicine – regularly monitor your goldfish and ensure proper tank maintenance.


In caring for your Celestial Eye Goldfish, it’s essential to remember their unique needs due to their distinctive features. Maintaining a well-filtered tank with a minimum size of 20 gallons, stable water conditions (pH range of 6.5-7.5), and a balanced diet that includes flakes, pellets, and live/frozen foods, will help keep your fish happy and healthy.

Keep in mind that these goldfish are not the best swimmers and may require extra attention to make sure they can thrive in their environment. With the proper care and consideration, your Celestial Eye Goldfish may become a charming and captivating addition to your aquarium.
