Characteristics of Shubunkin and how to keep it

The Shubunkin is one of the Japanese goldfish of the Japanese goldfish type. It is a goldfish with a distinctive body pattern and smart appearance. There are a few people who are not quite sure how to keep and enjoy the Shubunkin. In this article, I would like to explain in detail the characteristics of the Shubunkin and how to keep it.

What is Shubunkin?


Shubunkin is a fixed type of goldfish that is the result of free crossbreeding of a mixture of tricolor dimegane, wagane (crucian carp tail), and hibuna.The characteristics of Shubunkin include a body shape similar to that of Wagane and other species, with only the caudal fin having a longer crucian tail than that of Wagane or crucian carp. Its body color can be said to be miscolored, having the transparent scale characteristics of the mosaic of tricolor dekimekin and the normal scale characteristics of crucian carp. And Shubunkin is one of the most typical types of calico patterns.

Origin of Shubunkin

Shubunkin was created by Mr. Kichigoro Akiyama I and named by Mr. Shinnosuke Matsubara. Kichigoro Akiyama I also produced other types of Shubunkin, such as Akikin and Calico-Ryukin. And,The name "Shubunkin" comes from the beautiful reddish-red pattern on the light indigo (asagi) base color, which is almost an intermediate color between red and orange.

How to enjoy Shubunkin


How to enjoy Shubunkin,The difference is the straight form from head to tail fin and the gala of the body.For those who wish to enjoy the beautiful form, we recommend viewing it from above (kami-mi). When you view the Shubunkin from above, you can see the beautiful straight line of the body from the head to the tail fin. If you want to enjoy the patterns on the body, we recommend viewing it from the side (side view), such as in an aquarium. The collaboration of transparent scales and normal scales, called calico, is a very beautiful feature of Shubunkin. When illuminated, the transparent scales reflect the light and sparkle.

Points to keep in mind when mixing swimmers

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 compatibility between goldfish.If you put two incompatible goldfish together, there is a greater chance that they will quickly fight, or that only one of them will monopolize the food.Therefore, you should avoid mixing goldfish that are incompatible with each other, but as I explained at the beginning, there is no prohibition for goldfish to mix with each other, so if you want to mix goldfish, you may do so. Now, I will explain the goldfish that are compatible with Shubunkin and the goldfish that are incompatible.

Compatible goldfish

The goldfish most compatible with Shubunkin are,These are goldfish of the Japanese goldfish type, such as Wagane and Comet.The Shubunkin itself can grow to over 20 cm in length. Therefore, goldfish of the Wagane type, which are also large, are the most compatible. The next best match is the Dutch type, such as the Dutch lionhead and Azumanishiki, which are also good companions. Many Dutch types are good swimmers to some extent, and many of them are large, so they are a good match for Shubunkin.

Incompatible goldfish

Goldfish that are incompatible with Shubunkin are,These are Ranchu-type goldfish, such as Ranchu and Chotengan.Ranchu-type goldfish are not very good swimmers. Ranchu goldfish, in particular, are not good swimmers, so if they are kept together with Shumonkin, which are good swimmers, there is a possibility that Shumonkin will eat all of their food. If this happens, only Zhu Wenjin will get bigger and bigger, while Ranchu will remain small, so not many people keep them together.

Points to keep in mind when keeping Shubunkin


The Shubunkin is one of the easiest types of goldfish to keep. And it is especially recommended for beginners. And it is written in books and so on. It is easy to keep, and it is recommended for beginners,There is not much description of the speed at which the body grows, which is the biggest advantage and the biggest disadvantage of Zhuwen gold.The Shubunkin is a goldfish that has received the characteristics of species such as Wagane and Hibuna. Therefore, it is one of the fastest growing goldfish in terms of body size. Therefore,This goldfish is not suitable for those who plan to keep several kinds of goldfish mixed together in a small aquarium and do not intend to change the size of the aquarium.The reason is that if you keep Shumonkin with other goldfish, they may gradually grow larger faster than other goldfish, and if you keep them in a small aquarium, the gradually growing Shumonkin will make the aquarium cramped and stressful for other goldfish. On the contrary,The Shubunkin is a very suitable goldfish for keeping in large aquariums or ponds.Especially when kept outside, they may be targeted by outside enemies (cats, birds, etc.). However, once they grow to a certain size, they tend not to be attacked by outside enemies. Therefore, it is necessary to have them grow up quickly, so it can be said that Shubunkin are very suitable for keeping outside. For this reason, the Shumonkin is recommended for beginners, but we hope you will note that it is not so suitable for those who keep it in a small aquarium.
