Why do goldfish swell to death? Is it really a swelling death?

Yes, goldfish will swell to death. Because goldfish are artificially fed, they degenerate the problem of hunger and satiety. Therefore, when you encounter food, you will devour it in large quantities. Especially dry food. Dry food in the stomach lies in the expansion of water, so it swells to death.

The survival of goldfish directly depends on the dissolved oxygen in the water, and the excess food Goldfish cannot eat all of it, and the remaining part of it will sink to the bottom of the tank, and rot and stink, spoil the water quality and even emit a fishy smell. It is especially common during the mating period of goldfish, when water pollution prevents the air from dissolving, and at night when photosynthesis stops, goldfish and organic matter jointly consume dissolved oxygen. By dawn, dissolved oxygen in the tank is at its lowest.

After being fed, goldfish have poor tolerance to hypoxia and are very prone to death due to lack of oxygen. It is generally believed that goldfish will swell to death after being fed, but this is not the case

On the question of the goldfish swelling to death... I don't think it's hungry because I've been overfed and goldfish know to stop eating... As for the gods, it often happens that you will die if you feed too much, and it is generally believed that it is the reason for the swelling of artificial dry feed after eating it. . .

In addition, the oxygen demand increases after eating, and if the dissolved oxygen in the water is not good, it will die of lack of oxygen.

Any fish will swell to death, because the IQ of goldfish is too low

I agree with the opinion of the "crystal bottle".

My fish will be satisfied. You pay attention to the oxygen content in the water, or the breeding density.

First, it is caused by feeding some indigestible food or some food that is easy to swell.

Second, the water quality problem, the fish should be fed to change the water in time, otherwise it is easy to cause water quality deterioration, cause goldfish digestive system, and cause goldfish death.

Reasons: 1. Goldfish have no stomach, and the bait is directly into the intestines to absorb nutrients;

2. Goldfish are very greedy, they eat as much as they want, and they often pull while eating. In order to prevent goldfish from eating too much, the particles of the artificial dry bait should not be too large, and it is best to soak with water when feeding, which is conducive to goldfish digestion and absorption. If you accidentally feed more dry bait, the goldfish will swallow a large amount, and Zhiqi may cause bloating.

3. Goldfish need sufficient oxygen in the process of digesting food, if they are too full, swollen, and lack of oxygen in the water, it is possible to cause goldfish to die due to lack of oxygen, that is, people mistakenly think that goldfish are eaten to death.

Reasons: 1. Goldfish do not have a stomach, and the bait directly enters the intestines to absorb nutrients;

2. Goldfish are very greedy, they eat as much as they want, and they often pull while eating. In order to prevent goldfish from eating too much, the particles of the artificial dry bait should not be too large, and it is best to soak it with water when feeding or returning it to friends, which is conducive to goldfish digestion and absorption. If you accidentally feed more dry bait, the fish will swallow a large amount of bait, which may cause bloating.

3. Goldfish need sufficient oxygen in the process of digesting food, if they are overeaten, hungry and hungry, and lack of oxygen in the water, it is possible to cause goldfish to die due to lack of oxygen, that is, people mistakenly think that goldfish are eaten to death.
