1. Raising small fish at home is not enough because the living conditions of small fish are not met. Fish farming requires large tanks, clear water, and sufficient dissolved oxygen, while tropical fish also need the right water temperature. Insufficient conditions are not possible to successfully feed small fish.

2. Artificially cultivated ornamental fish live in a superior environment for a long time, and are less disturbed by changes in external climate and feeding conditions, so the disease resistance is poor, and if the feeding method is improper in home breeding, or the feeding conditions are not available, they will get sick or even die. Generally speaking, all those who are carefully raised and managed properly; Pay attention to stocking density and avoid changes in water temperature; Maintain good water quality, fresh bait, qualitative, quantitative, regular feeding and other main links, you can raise ornamental fish well.

How to raise small fish so that they don't die

The first step in raising fish is to buy a good fish tank, because only the right fish tank can raise good fish in ShanfengliangThe first thing to consider is how big the fish you want to raise, and if you have bigger fish, buy bigger fish. Fish tank. Buy smaller tanks for smaller fish.

It also depends on the space, because in addition to the space for movement, the fish also need oxygen, and a large enough space will have more oxygen, so choose fish tanks and long-term farming. The size of that fish matters. When you buy a fish tank, you can't buy fish right away, because you have to disinfect the fish tank, you have to keep the fish tank first.

You go to a place that specializes in fish farming and buy the kind that is used to disinfect fish tanks. It is known as potassium permanganate. This kind of thing, if you don't have it in the fish market, then you can go to a general pharmacy and sell it.

Use it to disinfect after purchase. After sterilization, put some potassium permanganate and water in the fish tank and leave it for three to four days. This completes the disinfection of the fish tank, and then you buy the fish back.

When buying fish, be sure to ask the boss to put some salt in the fish bag, because salt will prevent small fish from being deprived of oxygen. After bringing it back and putting it in the fish tank, the first thing to do is to observe if there are any special conditions for the fish that have just arrived. Take it easy!

Pay attention when changing the water. If you are in the city, I recommend that you do not put the fish directly in the tap water because there are chemicals in it and you can't feed the fish alive. You should keep tap water in the sun.

Go dry for a while, or if you have more money, you can install a purifier in the fish tank. It's also possible. Don't pour water into it every time you change it, as fresh water is not as good as old water.

You can only change a quarter of the water at a time, and the temperature of the water should be about the same as the temperature you add water, so that the small fish will not die because they can't adapt to the water change. This is a precaution for raising small fish. .

If you want to feed small fish, you must first pay attention to changing the water, and at the same time, you must feed it regularly and quantitatively, the temperature should be 1-2 higher than that of the adult fish, and the oxygen should be increased regularly.

Maintain water quality and control the frequency and timing of water changes; Control the water temperature to prevent disease in the fry.

The most important thing is water, and the temperature of the water should be controlled according to the climate, and the water quality should be maintained to control the frequency of water changes.

1. The fish in the river cannot be raised because of the lack of oxygen, if you want to feed, you need to keep oxygenating the fish, and keep the water flowing, otherwise it is easy to turn your stomach without feeding.

2. It is best to use the water in the river to raise the fish in the river, and the fish will die if you raise the fish in the tap water, because the tap water does not contain oxygen, and there is no beneficial nutrients for the fish, so it is best to dry the water or use the water in the river directly.

3. The fish in the river are also small, they will refuse to eat after being caught, and it is not easy to feed for a long time, and there is no problem with short-term feeding as long as the aeration pump is on, and a small amount of feeding can last for a period of time.

The reason why fish farming is old and dead is generally due to three reasons. First of all, the problem of the tank, the tank is not opened well, resulting in the residue of harmful bacteria, so that the fish cannot be raised, this situation needs to be reopened for disinfection. The second is the problem of water, the water is not well raised and the fish cannot be raised, we must pay attention to the trapped water, and at the same time cultivate bacteria.

There is also the problem of fish, the quality of the fish is not good, so it cannot be raised. In addition, if it is a tropical fish, it will die without heating equipment.

For people who raise fish for the first time, it is necessary to open the tank, if it is a tank without treatment, directly add water to raise fish, and generally raise it for a short time. The first thing to do when opening the tank is to disinfect, the purpose of which is to kill some latent harmful bacteria. The method of disinfection is very simple, just soak the fish tank with potassium permanganate solution for 3-4 hours, and then rinse it several times.

Fish farming requires water, and not raising water well will also lead to fish not being able to survive. The first step in water cultivation is to trap the water, except for the residual chlorine in it, although the content is not high, but it is still a threat to the health of the fish. Secondly, we should pay attention to the cultivation of bacteria and establish a good nitrification system to avoid ammonia nitrogen poisoning by the fish and cause their death.

If there is a problem with the quality of the fish, no matter how good the water is, it will not be able to feed it. When buying fish, you must pay attention to the selection, buy more energetic fish, do not choose those who do not like to swim, like to lie in the tank or have diseases on the surface of the body, these fish are not easy to raise. In addition, you should also pay attention to the species, some fish are difficult to raise, and it is easy for novices to raise to death.

If you are keeping tropical fish, you must take care to keep the water warm, too low a temperature will cause them to die. Usually the temperature should be controlled between 20-30, and you can use a heating rod to maintain a constant temperature to avoid too much change in temperature.
