Ranchu is,Like the Dutch lionhead, this goldfish has a well-developed fleshy mass on its head, but unlike other goldfish, it has no dorsal fin. All goldfish in the Ranchu lineage lack a dorsal fin. They also have a short tail fin.With features like that, the silhouette of the body appears to be gathered in the center, making it look round and round. This unique silhouette is one of the Ranchu's most attractive features. And the Ranchu is sometimes commonly described as the "king of goldfish. The Ranchu's large, grown-up appearance is a dignified one that is worthy of being called the king. It is said that the largest percentage of goldfish lovers in Japan are Ranchu lovers. Therefore, it can be said that the Ranchu division attracts the most attention at goldfish fairs.
Ranchu is,The breed was created from a goldfish called Marco, which was brought to Japan from China by the Dutch who were trading on Dejima Island in Nagasaki during the Edo period. The Marco is a goldfish named for its round body without a dorsal fin. And the main difference between the Marco and the Ranchu is the presence or absence of a head mass. Marco does not have a fleshy head like Ranchu. In Japan's oldest known goldfish breeding book, "Kingyo Sodate Gusa" by Yoshiyuki Adachi, published in 1748, the middle of the Edo period, there is a description of "Ranchu, Korean goldfish," which later became the Ranchu.Therefore, ukiyoe and other paintings made in the mid to late Edo period depict eggworms, and the ones depicted are called eggworms. It is said that the present-day ranunculid with a flesh-colored mass was improved by Kamekichi Ishikawa I, who was in Tokyo from the end of the Edo period to the Meiji period (1868-1912), thereby laying the foundation for the modern ranunculid. Since then, improvements have been repeated by numerous enthusiasts up to the present day.
Ranchu may be classified into two types, round-armed and long-armed, based on differences in body shape and the way they are fleshed out. Let us begin with the characteristics of the round-armed type.Marute is a ranchu with a rounded back when viewed from the side. The rounded back is the reason for the name "marute," and another characteristic of the marute is the presence of a mass on the head. Another characteristic of the round hand is that it has a mass on top of its head, as in the Dutch lion's head.Most types of rhomboids are the type that form on the top of the head. The round hand is close to the royal type of ranchu, giving it a rounded and cute appearance. Therefore, the round hand is recommended for those who like the cute appearance of the ranchu and the way it swims so hard.
Unlike the round hand, the long hand is characterized by the fact that when the ranchu is viewed from the side, the back is not curved, but is almost straight. The most distinctive feature of nagate is that it has a mass in the front part of its head. If you compare the two, you will clearly see that the long hand has a blister-like mass on the front part of the head.This is the most important characteristic of the long hand. And there are not many other species of goldfish that have such a characteristic of flesh flow as long-armed. In other words, we can say that it is a feature unique to nagate. Nagate is recommended for those who are attracted to the feature of fleshy flow, which is not found in other species, and for those who like smart-bodied individuals among Ranchu.
The best way to enjoy the ranchu is to look at the fleshy mass that develops as it grows and its unique dorsal-finless body shape. If you want to enjoy them, I recommend that you view them from the side (side view) in an aquarium. If you want to enjoy the round and cute shape of the Ranchu, it is recommended to view it from the side.As the ranchu grows, its abdomen becomes rounder, so if you use the side view, you can enjoy its changing body as it grows. If you want to enjoy long-handled ranchu, we recommend that you place them in a pot or other container and view them from above (top view) rather than from the side view. Since the head of the nagate is characterized by the growth of the fleshy mass in the front of the head, we recommend viewing it from above rather than from the side as a way to see the growing fleshy mass more clearly. The Ranchu is a species that has more pronounced features that can be appreciated with the side view and the top view compared to other goldfish, so it can be enjoyed with either view, and it can also be a point of difference in preference, so it is good to try both to find your own preference.
When mixing goldfish with other goldfish and other species, there is sometimes uncertainty as to what species is good and what species is not. First,There is no general prohibition against this or that when mixing goldfish with other species.Therefore, depending on the personality and environment of the goldfish you keep, even species that are said to be bad for each other may get along well with each other. However, there is also the matter of compatibility between goldfish. If you put incompatible goldfish together, there is a high possibility that they will fight or that only one of them will monopolize the food. However, as I explained in the beginning, there is no prohibition for goldfish to mix with each other, so if you want to mix them, you may do so. Now, I will explain the goldfish that are compatible with Ranchu and those that are not.
Goldfish that are most compatible with ranchu are ranchu-type goldfish such as Edonishiki (Edo Nishiki) and Sakura Nishiki (Sakura Nishiki).Since the Ranchu breed is a very poor swimmer, we recommend a Ranchu-type goldfish, which is also a poor swimmer, so that the goldfish will be less likely to eat food first or be chased by other goldfish, which will reduce stress.
Goldfish that are incompatible with ranchu are Japanese goldfish, such as wakin (Japanese goldfish) and comets, which are of the Japanese goldfish type.Many Japanese goldfish are agile and grow large in a short period of time. If they are mixed with Japanese goldfish, please be aware that the Ranchu may be eaten by other Japanese goldfish and the difference in body size may cause them to move away from each other.
Ranchu is,One thing you should definitely be aware of when keeping a Ranchu is that the Ranchu breed is difficult to keep. Difficult does not mean that they are impossible to keep. The Ranchu is sometimes referred to as the "king of goldfish," and many people who do not know much about goldfish have heard of it, if only by name. However, Ranchu tend to be more sensitive to changes in water temperature than other goldfish, and they have a very high risk of getting sick during the change of seasons. In other words, it is a difficult breed for beginners who are just starting out with goldfish to keep for the first time.We recommend that you first try to keep an easy-to-keep variety and get used to it. The Ranchu is one of the most popular goldfish breeds. For this reason, various enthusiasts are dedicated to keeping Ranchu, so it is fun to talk with them. Ranchu are sensitive to changes in water temperature, so you need to be especially careful when keeping them in places where the water temperature is likely to change. If you keep them in such an environment, it is advisable to use a heater. Ranchu goldfish have a lot of charm and enjoyment, so if you are interested in Ranchu, please try to keep them.
