1. if the goldfish are too full and feel like they are going to die,

the breeder needs to change the water for them immediately. The water quality must be dried, because the new tap water contains harmful substances, and long-term use will cause them to be poisoned. New water can effectively stimulate their intestines and stomach to speed up peristalsis, so that they can speed up excretion, so that the sick fish will return to normal after three or four changes of water. You can

also put a small amount of furazolidone and metronidazole in the water, which will have a certain digestive effect on them. During this period, a small amount of coarse salt is added to the water, which can also play a certain role in promoting gastrointestinal digestion. At the same time, keep the water temperature high, raise the temperature to about 30 C, and put a small amount of coarse salt in the water. This can not only play the effect of sterilization and disinfection, but also speed up their digestion, and after a period of time they will be excreted without problems. It is best to stop feeding them during

treatment. When changing water, pay attention to controlling the temperature difference and increase the supply of oxygen. So that they can return to normal more quickly.

? Breeders should follow the principle of eating less and more meals, and provide them with appropriate food every day. In addition, it is better to soak the prepared bait in water for three to five seconds before feeding them, so as to avoid the expansion of the feed in the water and make them eat too much.
