Fish at home die too fast?

At present, all fish should be goldfish, which is easy to raise, and goldfish are cold-water fish, so the temperature range is not particularly high, so the biggest problem should be water quality.

If tap water is not treated, it will basically die. Our tap water is disinfected with chlorine for sterilization. Fish can't stand it. Usually bask in the sun for about 3 days. If there is not enough time, boil it directly, then cool it to room temperature, and then use an air pump to oxygenate it before adding it to the tank. Lazy people can also add mineral water directly. That fish farming is very suitable for beginners and safe.

Then, on the issue of water temperature, although goldfish can resist heat and cold, the temperature difference between day and night cannot be too big. The air humidity in the north is low, there are few rivers and waters, and the temperature difference between day and night is easy to be large. People can't stand sudden cooling and sudden heating, so they must be careful. Especially on the balcony, it fluctuates too much.

In addition, although goldfish does not have to meet the requirements of tropical fish in water quality, its requirements for oxygen are much higher than those of tropical fish. Let me have a look. Yours is not an aerator, but a wall-mounted filter. Although the filter has the function of oxygen supply, it is still crowded to put six goldfish in this tank. The oxygen consumption of six goldfish can't keep up with your small filter, and you have to consider the oxygen consumption of the root system of green radish. Your small system needs three deaths to reach the oxygen consumption balance.

PS: Fish float in the absence of oxygen, so don't change water in a hurry. The temperature difference is too large (tap water is usually very cold), and the water quality fluctuates greatly. Sending you to this environment is like throwing you directly into a cold foggy day from summer. Basically, you will catch a cold, and the life of Xiaotou will be more fragile. What you need to do in the case of hypoxia is to pump oxygen, use an air pump or change a big filter (if you want to raise fish, good filtration is essential).

Also, the water in your tank is white. Do you still have nitrifying bacteria? Nitrifying bacteria are also large oxygen consumers in the early stage of reproduction. If they compete with goldfish for oxygen, goldfish will easily die of lack of oxygen.

For an old hand, goldfish can hardly be kept alive. When goldfish die, the basic conditions are not well matched, the oxygen is sufficient, the water quality is stable and the water temperature can be fed.

Then talk about other problems with your tank. These problems are estimated to be the death of a batch of tropical fish.

First of all, the filtration is too poor, the water quality is turbid and anoxic, fish manure accumulates, and there is no suitable place for nitrifying bacteria to breed.

Second, without a thermometer, it is impossible to monitor how much the water temperature changes.

Third, river sand cannot be used. This problem involves PH value and hardness of water. Most tropical fish in the market like soft water and weak acid water, and sand almost simultaneously causes water to harden and alkalize. As I said before, mineral water is the most suitable for raising. One reason is that mineral water is generally weak acid with low hardness (except in some areas), and another reason is that mineral water has no miscellaneous things such as chlorine, and its source is very stable, so novices don't need to worry about many things. The change of tap water to water can hardly exceed 1/3, otherwise the fish will die directly because of water quality fluctuation. Mineral water is different. The mineral water I used was moved out by a porter in nature, so it is no problem to change a whole box. Even the fish, such as Jinbozi, which requires high water quality, has no response at all. 10 yuan a barrel 10L Farmers can save a lot of heart. Other brands of mineral water should be tried by themselves to see if the water quality is good. I didn't evaluate it.

Finally, if something goes wrong, we must observe more and see if there is anything unusual. The problem is often in these places.
