Get to Know Ranchu Goldfish: King of the Goldfish

Ranchu goldfish are frequently referred to as the "King of the Goldfish," and I would definitely say it fits them. They have round-shaped bodies, no dorsal fins, a wen (a soft head growth that appears later on), and slow movement. As soon as I had my first encounter with these fish, I understood that this was something entirely different from other fancy fish breeds. Let's discuss this fish breed and its features further.

What Is a Ranchu Goldfish?

How Does It Differ from Other Fancy Goldfish?

The most distinguishing characteristics of this fish breed are a curved back, no dorsal fins, and specific head growth. There are many peculiarities in their structure that are different from those of other goldfish varieties.

Unlike regular goldfish, ranchu do not have elongated bodies. Their backs curve into an arch.

As far as their shape is concerned, ranchus look more rounded and compact when viewed from above.

Due to the absence of a dorsal fin, ranchu swim differently from other fish, since they cannot rely on it for support. They glide through the water.

Their unique body features cause them to be considered more delicate.

How Big Do Ranchu Goldfish Get?

Ranchu goldfish eventually grow to 6–8 inches. However, this might change depending on the environment in which they live.

There is quite a range of questions related to the size of these fish, and most people wonder how big ranchu goldfish get under different conditions.

Depending on whether they are kept in tanks or ponds, how they are fed, and what conditions the water provides, they will grow differently.

The bigger the space they have and the better the conditions are, the more they grow.

Ranchu Lifespan: How Long Do They Live?

Generally speaking, ranchus can survive for 5 to 10 years. Depending on how well they are taken care of, their lifespan might be much longer.

Their lifespan depends mostly on conditions, which include water, temperature, and feeding.

Therefore, having them implies certain responsibilities.

Ranchu Goldfish Care: Basic Guidelines

Caring for ranchu fish is more labor-intensive than caring for ordinary goldfish.

They depend heavily on the environment due to their physique.

Pond or Tank?

Ranchu fish can thrive in both tanks and ponds. However, taking care of them in tanks is much easier for most people.

Keeping fish in a tank means having better control over their environment.

While keeping them in a pond might also be possible, one needs to have some experience to deal with it properly.

Water Quality and Filtration

Good water quality is crucial. Since they release waste like any other fish, their environment gets dirty rather quickly.

To avoid this, one needs to use a filtration system, which will remove waste from the water.

Moreover, sufficient water circulation is required for proper oxygen circulation.

Therefore, using a reliable filtration system, such as a Poposoap solution, is advisable.

For outdoor setups with enough space, a carefully sized pond waterfall kit can also improve circulation and oxygen exchange, provided the water flow remains gentle.

Feeding Habits

They eat rather slowly. Therefore, faster fish may grab the food before they manage to.

It is best to feed them in quiet environments.

Or, if that is impossible, make sure that there are other fish that also eat slowly.

Mixed Keeping Guide

It is preferable not to mix them with active fish. The best option would be to keep them with other fancy fish that move slowly.

Thus, they will not face difficulties while eating.

Is a Ranchu Goldfish Suitable for Beginners?

Ranchu goldfish are suitable for beginners to keep as pets, but they are not the easiest option. They require more care than basic fish.

Because of their physique, they depend greatly on the conditions in which they live.

However, if you are ready to make some effort, keeping ranchu is worth considering.

Conclusion

These fish are beautiful and interesting. Nevertheless, they require some particular treatment. It includes water maintenance, filtration systems, etc.

One option for providing fish with appropriate living conditions is to use a Poposoap filtration system. With its help, this process becomes much easier.

Therefore, if you are ready to invest effort and money, it is possible to successfully keep ranchu goldfish as pets.
