Amazing 10 Methods: Ranchu Goldfish Care

Ranchu Goldfish Care is a great way to help you care for your fish. Ranchu Goldfish Care is very important because these Goldfish are one of the rarest types of Goldfish, and they have several different needs than other breeds.

We have put together this article with valuable information about caring for these fish, so if this is something you’re considering, we hope you will find it useful.

This information is for the new fish owner and their Ranchu Goldfish. The fish are generally pretty easy to take care of, but it’s still important to learn how they differ from other Goldfish.

General Ranchu Goldfish Care

Ranchu goldfish should be kept in a 10-gallon tank with water parameters of pH 7, hardness 0-25 dkh, temperature 78-80 degrees F, and oxygen content 5-15 ppm. The temperature should be cooled to 75 degrees at night.

They should be fed flake food for best results and every day. Flakes should be about the size of a rice grain, not a pea. Diet is very important for these fish, and a poor diet can cause various health problems in the fish.

Ranchu Goldfish should also have at least a quarter-inch of gravel in their tank. The water chemistry, temperature, and feeding habits can determine how much or how little they need this type of aquatic substrate, but they will generally benefit from it.

Overview Of Ranchu Goldfish

Ranchu goldfish are not only rare, but they can be sensitive to changes in water chemistry. You should test the water twice a week for the best results.  

If there is a sudden change in the pH and hardness to a too high level, then immediately lower it back down.  This is another reason you should have good test kits on hand when caring for these fish.

Amazing 10 Method Of Ranchu Goldfish Care

1. It’s very important to keep their water clean and filtered. This is true for all Goldfish but especially critical for Ranchu Goldfish, which have a very sensitive immune system.

2. They do best when kept at a 64-69 degrees Fahrenheit temperature. You can utilize a heater or a chiller to make sure this is the case, but remember that if you use a chiller to drop the temperature, you will need to raise it gradually as spring comes in on the calendar.

3. They need to have a good filtration system. This will help ensure the waste in their water is removed as it is produced and that their water is kept clean overall.

4. It’s a good idea to take your Ranchu Goldfish out of the aquarium for 2-3 hours a day so they can swim freely in room temperature air. As always, make sure they are in an area where they cannot be disturbed or harmed while they are out of water.

5. For their health and well-being, it’s a very good idea to feed them at least twice daily. This means they need to be fed BEFORE 9:00 AM and AFTER 5:00 PM.

6. It’s also a good idea to provide your fish with some form of shelter from the bright light in their tank. On the side of the tank is generally ideal as this provides plenty of hiding places for them.

7. It’s important to provide your Goldfish with a daily amount of tank water. We do this by adjusting the amount of water provided within their daily feedings.

8. You should make sure they have at least 2-3 inches of tank space outside their home or aquarium tank. This is for their well-being and for them to swim around freely in the room.

9. If you know anyone else who owns a Ranchu Goldfish, it’s a good idea to only have one in the same tank. This is because these fish tend to be quite peaceful but make sure that you know their needs and tank space before adding another.

10. For Ranchu Goldfish Health, they need to be given clean water, and they also need some drops of aquarium salt in the water at all times.

Are Ranchu Goldfish Easy To Take Care Of?

As with many Goldfish, Ranchu Goldfish do not like to be held and can even hate being held. They are very territorial fish that feel threatened by other fish in their tank, so it’s a good idea for them to be left alone for at least part of the day.

There are several different types of Ranchu Goldfish available, so there is a variation in temperament and care needs from these fish.

Can Ranchu Goldfish Live Alone?

In general, Ranchu goldfish require a minimum of 2 gallons of tank space. Mainly because they need to be able to move around freely, but also because they will generally get more aggressive if they cannot meet their needs. They are usually very peaceful and don’t look for any reason to fight with each other.

We always recommend having at least one other (smaller) Goldfish in a tank with your Ranchu Goldfish. This is so that they have some company, competition, and exercise.

How Many Times Do You Feed Ranchu Goldfish?

These fish can be very picky about what they eat, so we recommend feeding them once a day to ensure they are getting all of the nutritional benefits from their diet.

You should feed them at least every 12 hours, but again we recommend feeding them more often than that if you want the best results in their health and overall well-being.

The amount you feed your Goldfish will depend on what type of food you buy and how many flakes per day they weigh.

What Do You Feed Ranchu?

In our opinion, we think Ranchu Goldfish care is one of the most difficult kinds of Goldfish to find good food for. They tend to be extremely picky eaters, and they don’t love most available foods.

We’ve tried a lot of different types of flake food, and none worked as well as Ranchu Goldfish Care. We have developed a special formula that has all the nutrients you would need for your fish in it, and it works very well for them.

Special Notes

When taking care of your Ranchu Goldfish care, it’s always a good idea to make sure that their water quality remains healthy. One of the best ways to do this is by cleaning their tank once a week, even if there is no ammonia in the water or any other signs that their water is not healthy.

We recommend running their tank for about 30 minutes after cleaning with a reputation for good bacteria in it. This will help ensure that your fish can continue to have good health and strong immune systems although you have cleaned the tank.


As you can see, Ranchu Goldfish care can be a very interesting and unique fish that many people are interested in. They are a great choice for new and experienced fishkeepers alike.
