Origins and Natural Habitat

Jikin goldfish have a fascinating history that can be traced back to Japan. They were developed in the Owari region, with Suonokami Amano being credited as the breeder responsible for this beautiful breed. These fish were selectively bred from the Wakin goldfish and soon became the local goldfish of the Nagoya region.

In their natural habitat, Jikin goldfish are accustomed to ponds and slow-moving waters. To replicate this kind of environment in your aquarium, you should aim for a steady water flow and add some plants to make your fish feel comfortable.

When it comes to tank or pond mates, your Jikin goldfish will thrive with other goldfish and similarly mild, even-tempered fish. This peaceful nature makes them a popular choice for aquariums and ponds with a variety of aquatic creatures.

Remember to keep the water clean and invest in a good quality filter to ensure your Jikin goldfish remain healthy and happy in their new home. With proper care and attention, you’ll find these stunning and unique goldfish to be a delightful addition to your collection.

Physical Characteristics

Size and Shape

Jikin goldfish possess a unique body shape, making them stand out from other goldfish varieties. They have slim and elongated bodies with a beautiful and distinctive four-lobed, split tail. This tail, often referred to as a “peacock tail,” gracefully fans out when the fish swims. Typically, adult Jikin goldfish grow to about 8-10 inches in length.

Color and Markings

The coloration of Jikin goldfish is another fascinating aspect of their appearance. These fish have a silvery-white base color with red markings on specific points. The six red points can be found on their lips, dorsal, ventral, pectoral, caudal, and anal fins. Some Jikin goldfish might have a few scattered colored scales on their bodies, but the ideal specimen has a pure white body with the six distinct red points. However, remember that the appearance of your Jikin goldfish may vary and still be a beautiful and healthy member of your aquarium.

Lifespan and Growth Rate

Jikin goldfish are known for their long lifespan, with some living up to 20 years when properly cared for. To ensure a healthy and vibrant life for your Jikin goldfish, pay close attention to their growth rate and provide optimal living conditions.

Goldfish growth rates can vary, but they are generally considered slow growers. It’s important for you, as the owner, to monitor the growth of your Jikin goldfish and adjust their environment accordingly. Proper diet, clean water, and suitable tank size play a significant role in their growth and well-being.

Your Jikin goldfish’s growth can be impacted by factors such as genetics, diet, water quality, and tank size. To encourage healthy growth, maintain a balanced diet for your Jikin goldfish. This includes providing them with a quality pellet food along with occasional treats like bloodworms, brine shrimp, or vegetables like peas.

It’s important to keep in mind that overcrowded tanks can stunt the growth of goldfish. Ensure that your Jikin goldfish has ample swimming space and the right water parameters – a suitable temperature range, pH level, and proper filtration system – to contribute to a healthy growth rate.

By following these guidelines, you can give your Jikin goldfish the opportunity to thrive and enjoy a long and healthy life.

Diet and Feeding

Feeding your Jikin goldfish a proper diet is essential to ensure their health and longevity. They enjoy a varied diet consisting of insects, small crustaceans, and plants. To meet their basic nutritional needs, you can provide them with a high-quality pellet or flake food. Feed your Jikin goldfish once or twice a day.

It’s important to avoid overfeeding since it can lead to health issues. A good rule of thumb is to give them only the amount of food they can consume in 2-3 minutes. If you notice leftover food after this time, reduce the amount you are feeding them.

For added enrichment and nutrition, incorporate live foods into their diet occasionally. Brine shrimp, daphnia, and bloodworms are excellent options. Live foods not only provide essential nutrients but also help keep their foraging instincts sharp, preventing boredom and the uprooting of plants in your tank.

Additionally, supplement their diet with fresh vegetables like spinach, lettuce, or peas. This can improve their digestion and overall health. Make sure to blanch the vegetables to soften them up and remove any potential chemical residues.

Remember, a well-balanced diet is vital for the happiness and well-being of your Jikin goldfish.

Behavior and Temperament

Jikin Goldfish are known for their friendly and mild temperament. They usually get along well with other goldfish and tank mates, making them a popular choice for ponds and aquariums. You’ll find that your Jikin Goldfish are rarely hostile or territorial.

That said, do note that Jikin Goldfish are omnivores, which means they’ll eat both plants and small animals. In some cases, they may end up munching on fish that are significantly smaller than them. So, when selecting tank mates, it’s wise to opt for companions that are closer to their size.

When it comes to keeping your Jikin Goldfish happy and stress-free, it’s important to maintain a clean and well-organized tank environment. Allocate designated areas for feeding, hiding, and swimming. This way, your Jikin Goldfish will be able to explore, interact, and coexist peacefully with other aquatic buddies, making the tank a comfortable home for everyone.

In summary, you can expect Jikin Goldfish to exhibit a friendly and even-tempered behavior, fitting well into most aquatic communities. Just remember to choose tank mates carefully and maintain a pleasant environment to ensure their happiness and well-being.

Care and Tank Requirements

Tank Size

To provide a comfortable environment for your Jikin Goldfish, you’ll need a tank that holds at least 20-30 gallons of water. Keep in mind that each additional Jikin requires an extra 10-20 gallons. This ensures that the fish have enough space to swim freely and stay happy.

Water Parameters (Temperature and pH)

Maintaining the proper water parameters is essential for your Jikin Goldfish’s health. Ensure that the tank temperature stays between 65°F and 75°F. When it comes to pH levels, aim for a neutral range of 7.0-7.5. Regularly test the water to achieve these parameters, and make adjustments as required.

Tank Setup and Decorations

Jikin Goldfish enjoy a well-decorated tank with ample hiding spots. You can add rocks, driftwood, and other decorations to make their home more interesting. Remember to avoid sharp objects to prevent injury to their delicate fins. A mix of artificial and live plants helps create a natural environment, but be cautious as Jikin Goldfish are known to nibble on some live plants.

Filtration and Aeration

Providing good filtration is critical for maintaining your Jikin Goldfish’s health. A high-quality filter not only removes debris and harmful toxins, but also generates water movement, essential for proper aeration. Goldfish produce large amounts of waste, so choose a filter with a strong output. Lastly, consider adding an air pump or air stone to help maintain optimal oxygen levels.

Suitable Tank Mates

Jikin Goldfish are known for their mild and even-tempered nature, making them great additions to community aquariums. When choosing suitable tank mates for your Jikin Goldfish, it’s important to consider the compatibility of the other species in terms of behavior and environmental needs.

Some ideal tank mates for Jikin Goldfish include:

  • Newts
  • Zebra Danios
  • White Cloud Mountain Minnows
  • Corydoras Catfish
  • Ghost Shrimp
  • Apple Snails

Keep in mind that while these species can make good companions for your Jikin Goldfish, it’s always important to monitor the interactions between the different species in your tank. Make sure the tank is large enough for all inhabitants and ensure the water parameters are suitable for everyone inside. With proper tank management and a keen eye on the well-being of your fish, your Jikin Goldfish and its newfound friends should live happily together in their underwater home.


In caring for your Jikin Goldfish, it’s essential to pay attention to their specific needs. Proper tank size, water parameters, and suitable tankmates are all factors that contribute to their overall well-being.
