Characteristics of Wakin and how to keep it! The origin of goldfish that are durable and easy to keep!

What is Wakin

What kind of goldfish is Wakin?


Wakin is one of the original breeds of goldfish, and is characterized by its body shape resembling crucian carp. Goldfish have been popular for many years due to their ease of breeding and low prices. The shape of the caudal fin is common for Japanese gold Carp tails, three tails, four tails, etc.There are several types.


Recently, high-quality Sarasa Wakane and improved Wakana type varieties with various body colors and shapes have appeared.


History of Wakin

Goldfish originated in Wakin


Wakin was born in the Pu dynasty of China, and it is said that the prototype was a fixed red individual (Hibuna) by mutation of crucian carp. This crucian carp is called Giberiobuna, a species closely related to the Japanese gimbuna, and inhabits a wide range of regions, from East Asia to the temperate regions of Europe.


Later, in the Muromachi period, the first goldfish that came to Japan was the Wakin, and it is said that it got its name to distinguish it from the various improved breeds that arrived in the Edo period.


There are goldfish that are sold under the names of Koaka, Anekin, and Oane, but basically they are the same breed as Wakin. Because Japanese gold is very cheap and produced in large quantities, it is also distributed as live bait (bait gold) for carnivorous fish.


Wagyu for feeding is sold by size, and the size increases in the order of small red < big sister gold < big sister.

Wakin is also familiar with goldfish scooping


Speaking of Wakin, goldfish scooping is also familiar. Yamatokoriyama City in Nara Prefecture is also a major producer of Japanese gold, and the national goldfish scooping championship is held there. Scooping up goldfish with a tool called a poi, which is made of thin paper, seems to be easy but difficult, and has long been popular with many people as a summer festival tradition.

how to keep wakane

Wakin are very easy to keep and are hardy fish. Let's keep the basics and enjoy breeding Wakin.

Breeding equipment

Wakin is a surprisingly large fish, and can grow to nearly 30cm if kept normally. Wakin, which is about 3cm in size, which is often seen in goldfish scooping, can be kept in a 45cm tank, but as it grows, a 60cm standard tank is required at least.


In addition, the Japanese goldfish eats a large amount of food and is a fish that easily pollutes the water. Let's maintain clean water quality by using the most convenient drop-in type filter, top filter and external filter.

Wakin is also suitable for outdoor breeding. Breeding outdoors in direct sunlight will result in a larger and more colorful Wakane. How to make a pond in the garden Surprisingly, we also recommend raising plastic boats using plastic boats. If you have enough space, please try it.

Water temperature/water quality

Wakin is very durable, so you don't need to worry about water temperature or quality as long as you mix it with water. Since Japanese goldfish are often farmed in Japan, they are resistant to cold and heat, and can be raised well without using heaters like foreign goldfish. When breeding without a heater, it is important to pay attention to diseases in spring and autumn when the water temperature changes significantly, and to reduce the amount of food in the winter when the water temperature is low.


In the summer, the water quality tends to deteriorate, so please change the water frequently.


Wakins are omnivorous and will eat anything, including small aquatic animals and aquatic plants. Basically, there is no problem with commercially available goldfish food, but if you want to enhance the body color, we recommend food for enhancing the color and red beetles. Also, if you leave the house for a long time, it is recommended to keep Kabomba and Anacharis in the aquarium.

If it is a Japanese goldfish, it is possible to swim together as long as there is no significant difference in length. If there is too much difference in body length, the big Wakin may poke the small Wakin, and in the worst case, the small Wakin may die, so be careful.


In addition, round-shaped goldfish such as Ryukin and Deme-gane have weak swimming ability, whereas Japanese goldfish have strong swimming ability, so there is often a difference in scramble for food. It is a good idea to use goldfish of the same body type as much as possible.
