Points for choosing goldfish (beginner's level)

When you buy a goldfish, you want to keep the best goldfish possible. In this article, I would like to explain some points that even a newcomer can understand among the many goldfish available.

About the disease

You must be sick.

Among the many types of diseases, be especially careful of "white spot disease.White spot disease is a disease caused by changes in water temperature and other factorsSo, it is a disease that is likely to be contracted by any number of specialty stores. And,White spot disease will spread to other goldfish in the same environment, so if you bring a goldfish with white spot disease home, there is a very good chance it will be infected!It is. To identify white spot disease, if there are white spots on the tail fin, you may have white spot disease. Note that it is only the tail fin. If there are no white spots on the caudal fin but white spots on the head or pectoral fins, there is a high possibility that it is not white spot disease. However, if you are concerned, we recommend that you refrain from purchasing the fish if it has white spots anywhere on its body.

Water Temperature

What is the water temperature?

This is more about water temperature, so that you don't have to worry about it when you bring it home than when you buy it. If,If there is too much difference between the water temperature the goldfish lived in before you bought it and the water temperature after you buy it and bring it home, it will be stressed, and its immune system will be compromised, making it very likely to get sick.The "new" is a new way of doing business. We will try to minimize this difficulty as much as possible.I recommend paying attention to the water temperature when purchasing.The following is a brief description of the pet shop. It is important to note that in some large pet stores, the inside of the store may be air-conditioned or heated. In such cases, the water temperature may rise or fall in tandem. For example, when you purchase goldfish in the summer, the water temperature in the aquarium may be low in proportion to the air conditioning in the store. If the difference between the hot outside temperature and the water temperature is too great, the goldfish may become ill due to stress, so you need to be careful.

About the type

What type of goldfish is it?

When purchasing goldfish for the first time, some people may be surprised at the variety of goldfish available. Some people may be surprised at the variety of goldfish available when buying for the first time, and some may be confused about which goldfish to buy. For those people, let's take a look at the followingI recommend choosing a goldfish that you have seen before, such as a goldfish scoop.Goldfish are a very versatile fish. Goldfish have a variety of characteristics, such as the environment in which they are kept and their susceptibility to disease. The fun of goldfish is their diversity, but for beginners, this diversity can be intimidating. For this reason, we recommend the "Wagane" variety of goldfish, which are often used in goldfish scooping. Other types of Japanese goldfish such as "comet" and "shubunkin" are also recommended. However, there is one thing you should be careful about when purchasing Wagane. That is,Wagane and other species grow quickly. Therefore, it is not recommended for those who are planning to keep them in a small aquarium or those who do not plan to replace their existing small aquarium with a new one.For such people, we recommend a type of goldfish such as "Ryukin". In this way, there is a possibility that the environment in which they are kept may make them unsuitable, so if you are concerned about this, we recommend that you ask when you make a purchase.
