Points for selecting goldfish (intermediate 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 Water

About the color of water

In the beginner's course, I explained to watch for disease, but in the intermediate course, I will explain the color of the water this time because it is a risk hedge by squashing any possible disease in advance. Some people who are thinking about purchasing goldfish at specialty stores actually watch them and consider whether to buy them. If the same type of goldfish is displayed and sold in multiple aquariums, it is natural to choose the aquarium with the lowest possibility of being affected by disease. However, there is no way to compare if you do not know the point of comparison.The first thing to check is the color of the aquarium. If possible, try to avoid purchasing goldfish with white or milky-white aquariums. White or milky-white water does not have a good balance of bacteria and other organisms, so there is a greater chance of disease from pathogens.If you are concerned or are not familiar with the disease, please refrain from buying goldfish in white or milky-white aquariums.

Goldfish wounds and injuries

When purchasing goldfish, there are a variety of goldfish to look at in specialty stores. You have to choose from among them. When choosing a goldfish, though, you have to consider the superiority of the goldfish,The first thing you should be concerned about is whether it is wounded or injured. For example, if the tail fin is bent to one side or the other, or if the goldfish does not have a good balance between the left and right sides, avoid it as much as possible.Goldfish that are not very well balanced from side to side are always under stress because their bodies are always out of balance, so the risk of disease or death is very high. However, it is not always the case that all goldfish with wounds or injuries are bad. Goldfish that have just arrived at a specialty store may come in dozens to hundreds in a bag. If the injury is only one or two pieces of scale, there is a high possibility that it will be cured, so there is little need to worry. If you can distinguish between injuries that can be healed and those that cannot be healed, you will have a better chance of finding the goldfish you want.

Compatibility

Compatibility between varieties

In the beginner's level section, we explained how to keep a variety of goldfish that are easy to keep, but in the intermediate level section, we will explain how goldfish are compatible with each other. When keeping new goldfish, there are few people who already have goldfish in the aquarium they plan to put in. In such a case, you don't want them to fight with your existing goldfish and you want them to get along well with each other. At that time, the most important thing to consider is compatibility. Compatibility is a part that can only be understood if you let them swim together.There are two parts that can be known in advance. The first part that is known in advance is the species. For example, if you mix Japanese goldfish and Ranchu goldfish, the Japanese goldfish may chase the Ranchu goldfish and weaken the Ranchu goldfish.If you know the type of goldfish you are currently keeping, you can reduce your anxiety by purchasing a goldfish that is compatible with it. If you are not sure which type of goldfish is compatible with your current goldfish, we recommend that you ask the store staff for advice.In addition to breed, you should also be aware of differences in body size. If the body sizes are too different, the larger goldfish may have difficulty eating the smaller goldfish when the larger goldfish eats the food, and if this continues, the size difference may widen further.So you should first consider how much difference there is in body size.
