Jikin Goldfish Overview

The Jikin Goldfish has a pale white body with vibrant red fins. Its unique look will add lots of fabulous color to your aquarium—and they’re very resilient. These gentle fish will get along with other creatures in the tank, as long as they aren’t small enough to eat!

These fish are hardy, too. You can be brand new to the fish-keeping world and keep these goldfish successfully.

How Much Do Jikin Goldfish Cost?

Jikin Goldfish are typically not found outside of their home of Japan. They’re comparable in price to the Wakin Goldfish—which are pricier than most.

They are typically $15 to $25 per fish. You might have to pay more if they are nearly impossible to find in your area.

The trickiest part is finding this particular type of goldfish, to begin with. These fish were bred in Japan—and that’s where most of them exist today. They may gain and grow in popularity in the coming years, but right now, they’re sparse.

Typical Behavior & Temperament

Generally, these goldfish are incredibly mild and even-tempered. They tend to do very well with other goldfish and tank mates alike. For this reason, people love to put them in ponds and aquariums with their other fish and creatures.

These fish are never really hostile or territorial. If you notice that your goldfish is becoming aggressive, it’s probably due to underlying circumstances—whether it be  poor health, crowded space, or molting issues.

Appearance & Varieties

The Jikin Goldfish has a very distinct look that visually separates them from other goldfish. They are silvery-white with six red points. They have red points on the lips, dorsal, ventral, pectoral, caudal, and anal fins.

One desirable attribute is that they have a split four-lobed tail, referred to as a peacock tail. They swim gracefully through the tank, providing an extreme aesthetic appeal.

Some Jikin Goldfish can lose this vivid red color as they age, dulling down to a pale orange. It’s common with age and doesn’t point to health issues.

While there are several kinds of goldfish, Jikins are uniform in color and body type.

How to Take Care of Jikin Goldfish

Habitat, Tank Conditions & Setup

For your Jikin Goldfish to have a long-lasting, healthy life, their habitat set up is of utmost importance.

Aquarium Size

It would be best to have at least a 20-gallon aquarium for your Jikin, if you have a pair. Goldfish grow very fast, so the appropriate space is necessary.

Temperature & pH

Your Jikin’s water should stay between 68° to 74° F. Goldfish aren’t as sensitive as some other fish with pH, but it should be between 7.0 and 8.4.

Make sure not to drastically change pH or temperature since it can stun or kill your goldfish.


There are plenty of plants that will work for your goldfish aquarium. Not only do plants look beautiful—they also provide nutrition and oxygen for your fish.

Some great selections are:
  • Pothos
  • Java Moss
  • Amazon Sword
  • Anubis
  • Java Fern
  • Crypts
  • Water Sprite
  • Hornwort
  • Brazilian Pennywort
  • Cabomba


While it’s true that goldfish can “live” in a stillwater fishbowl, it’s definitely not the best environment for them. They need filtered, clean water to thrive.

A simple canister filter will pump water through the tank to clean debris and create oxygen.

If you're a new or even experienced goldfish owner who is having issues understanding the intricacies of water filtration, or just wants a bit more detailed information on it, we recommend that you check out our best-selling book, The Truth About Goldfish. 

The Truth About Goldfish New Edition

It covers everything about creating the most ideal tank setup and more!


Lighting is vital for goldfish so they can have a proper sleep/wake schedule. They need 12 hours of direct light, 12 hours of darkness.


Gravel is a popular choice for substrate in goldfish tanks. It’s attractive, cheap, and simple to change. Try to make sure that the gravel pieces are large enough so your goldfish won’t swallow fragments by accident. A good rule of thumb is to buy gravel the size of a pea or larger.

Sand is another popular choice among goldfish owners. It looks very natural and serves as a surface for good bacteria.

You can always just have a substrate-less tank. It’s not as aesthetically pleasing, but it’s easy to manage.

Are Jikin Goldfish Good Tank Mates?

These goldfish make excellent tank mates. They pair very well with several different types of fish.

The best pairings for goldfish are:
  • Bristlenose Plecostomus
  • Apple Snail
  • Platy Fish
  • Bloodfin Tetras
  • Barbs
  • Danios
  • White Cloud Mountain Minnows
  • Scissortail Rasbora
  • HIllstream Loach
  • Bamboo Shrimp

Goldfish are highly social creatures, and if you change them alone, they might be very depressed. You should always have at least two goldfish together if nothing more.

Try not to pair your goldfish with certain species, however. Always check before you add another species to your tank.

What to Feed Your Jikin Goldfish

Jikin Goldfish are omnivores, so they get sustenance from both plants and meat sources. Usually, you can feed your goldfish a diet of fish flakes, but you can offer plenty to switch things up a bit.

Jikin goldfish eat:
  • Crickets
  • Bloodworms
  • Mealworms
  • Daphnias
  • Shrimp
  • Shelled peas
  • Skinned grapes
  • Watermelon
  • Algae
  • Corn
  • Zucchini
  • Leafy greens
  • Broccoli
  • Carrots
  • Cooked rice

You can treat them to a snack every once in a while, but be careful not to overfeed them, as they can eat themselves to death.

Keeping Your Jikin Goldfish Healthy

There are steps you need to take to keep your Jikin swimming happily.
  1. Keep water conditions ideal. You’ll need to keep the tank very clean and make sure that the temperatures remain tepid.
  2. Offer a well-balanced diet. You’ll need to give your Jikin a variety of nutrients to ensure their nutrition is optimal.
  3. Put plants in your aquarium. Plants look fantastic in an aquarium, and they’re great for your Jikin’s little ecosystem.
  4. Detoxify the tank. Ensure you keep the correct pH in the water and that there are no harmful bacteria in the tank.
  5. Make sure your aquarium is big enough. If your Jikin is in too small of a space, it can stunt their growth and shorten their lifespan.


If you’re interested in breeding your Jikin, it might not be as simple as you think. It requires effort and special conditions—plus, it can be expensive.

  1. Make sure the environment is ideal. Everything needs to be perfect—from the temperature to the lighting.
  2. Amp up the diet of your Jikin. You’ll need to start feeding your Jikin fish a few extra calories.
  3. Mimic the spring season. Jikin Goldfish breed in the spring. By cooling down their environment, then slowly warming it, instincts will take hold.
  4. Cycle water daily. To keep the water clean, make sure to cycle the water and clean the cage.
  5. Sex and select all of your goldish. You have to make sure you have the appropriate number of males and females. Then, choose the best breeders for reproduction.
  6. Try to spawn naturally or artificially inseminate. See if your Jikin will have eggs organically. If not, you can try to assist the situation.
  7. Separate the parents from eggs. So none of the goldfish eat the eggs, separate the breeders as soon as you spot some.
  8. Wait patiently. Goldfish eggs hatch in 2-7 days.
