The fish tank is about 80CM 120CM and 24 hours a day

#1.Disinfect the tank thoroughly! Soak the fish tank with about 3%--5% potassium permanganate. Then wash repeatedly to prevent potassium permanganate residue.

2.The tanked tap water should be left for about 3 days! Because there are artificial additives in tap water. The water changed has to be treated like this! If you shorten the drying time or don't dry it, you can do it, but you must add some soda to it, or Yulebao, and put one grain for every 20 kilograms of water.

3.Open the tank, buy a few small fish and put them in, if you are okay for a week, the tank is fine! Then buy big fish and put it in.

4.Then there is the filtration equipment of the tank (physical filtration, biochemical filtration), and the feeding equipment.

Nothing else! Go to the professional fish farming forums more!

I've been raising goldfish for forty years, and I'm a self-proclaimed master, and I don't hear what you say about bubble disease, and white spots are the most common. Wait for the fish to run out of water, let the fish tank dry for a period of time, the bacteria will die more than the water, clean and wash before use! Put the water in a few days to buy fish, look at it clearly when you buy, don't buy sick fish, go home and observe every day, early detection and early isolation.

When the fish defecates, they should be fed in the sun, and the water temperature should be controlled, and there should be no problems.

You had better add a filter, and if you buy fish or sick fish, it is best to soak them in diluted potassium permanganate solution for a few hours.

It's possible that something climbed in and when you come back he climbs out again, and if not, it's a matter of feed.

If you buy fish in the spring, you will die. The fish bought is sick in itself.

The water is dried for a period of time before the fish are raised.

<> fish tank generally does not need to be oxygenated 24 hours a day, unless the oxygen consumption of the fish is relatively large, or the breeding density is very high, so that if the oxygen is not enough, it needs to be oxygenated all the time. Under normal circumstances, 2-4 hours of oxygen per day is fine, if it is summer or rainy weather, due to the reduction of dissolved oxygen, it is necessary to extend the oxygen time, 4-6 hours of oxygen per day, and it should be carried out separately.

Goldfish generally do not die without oxygen overnight. If the tank for raising goldfish is relatively large and the number of goldfish is not too large, it will not affect them if they are not oxygenated overnight. They can survive even without oxygen.

However, if there are a large number of goldfish in the fish tank, and the fish tank space is not particularly large, then oxygen is needed. If the tank is very small and the number of fish kept is very large, then they may also die if they are not oxygenated overnight. <

The oxygen consumption of goldfish is relatively high, and normally only four to eight goldfish can be raised in a one-meter-five fish tank, so as not to cause them to lack oxygen. Some other low-oxygen fish can be raised in such a large tank.

Whether goldfish will die without oxygen overnight is related to their feeding density and fish tank space, which is divided into two situations:

1. If the fish tank itself is relatively small and the number of goldfish raised is relatively large, if the oxygen is stopped, their consumption can easily lead to insufficient oxygen content in the water, which will lead to their death.

2. If the fish tank space is relatively large and the goldfish are relatively small, then stopping for a night without oxygen will not cause them to die.

So in order to prevent them from becoming hypoxic, try not to feed them at night, which will increase their consumption of oxygen. If the stocking density is large, it is best to give them an uninterrupted supply of oxygen at night, or use lights to irradiate the aquatic plants at night to allow the aquatic plants to produce some oxygen. In this way, when there is a sudden oxygen outage at night, it will not cause the death of the goldfish.

There are the following reasons. Please be symptomatic.

1.Anoxia. 2.The water quality is not good, which causes the fish to get sick.

3.Tap water should not be used directly, but water that has been trapped for at least three days should be changed.

4.It is possible that the goldfish is strutted to death, and the goldfish does not know that it is hungry.

5.The difference between the water temperature and the water temperature in the fish tank should not exceed two degrees, otherwise the fish will be irritated.

Raising goldfish only requires the following simple questions to keep in mind.

1.If you don't have old water at home before you buy fish, you need to use water that has been trapped for seven days (i.e., tap water that has been in other utensils for more than seven days) to raise goldfish. Don't rush into the tank after buying home, first soak the plastic bag containing the fish into the fish tank for 10 to 20 minutes before opening it, let the water in the tank pour into the bag several times, and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality.

2.In addition to eating artificial bait, goldfish prefer to eat bloodworms, earthworms, small shrimp, egg yolks, etc., to ensure that the bait is fresh, and the spoiled ones can not be fed.

Goldfish can be fed once a day, fed at a fixed time, goldfish do not know hunger, so each time they are fed eighty percent full, feeding within five minutes is appropriate.

Goldfish is a cold-blooded animal, so it is not afraid of cold, but since you are kept indoors, I believe that the temperature should not be very low, generally the water does not freeze, it is fine, but try to keep the water temperature constant, hot and cold will definitely catch a cold.

5.If there is no filter, it is necessary to suck out the fish feces on time every day, and then add the same amount of trapped water as the suction (need to be trapped for three days), so that the water is only a little, and the water can be kept clean and the oxygen is injected. Put the trapped water next to the fish tank a few hours before the water change, so as to ensure that the new water to be replaced is kept at the same temperature as the water in the fish tank, and the fish will not be irritated.

<> goldfish farming does not require 24 hours of oxygen. Raising this kind of fish, it is best to inject oxygen, especially when the tank is opened, oxygen can help the fish tank to establish a nitrification system, which is very good for the healthy growth of goldfish in the future. Oxygen when goldfish is sick can increase the amount of dissolved oxygen in the water, indirectly promote the metabolism of goldfish, and help goldfish recover their health.

However, there is no need to oxygenate the fish tank all the time, and under normal circumstances, only 2-4 hours of oxygen are needed a day.

1. Does the fish tank need to be oxygenated for 24 hours?

2. Does the fish tank need to be oxygenated all day?

3. How long does it take for the fish tank to oxygenate every day?

4. Does the 24-hour oxygen in the fish tank have any effect on the fish?

1.Fish tanks generally do not need to be oxygenated 24 hours a day, unless the oxygen consumption of the fish is relatively large, or the density of local breeding is very high, so that the oxygen is not enough, it is necessary to keep oxygen.

2.Under normal circumstances, it is OK to inject oxygen for 2-4 hours a day, if it is summer or rainy weather, due to the reduction of dissolved oxygen, it is necessary to extend the oxygen time, 4-6 hours a day, and it should be carried out separately.

Although the oxygen consumption of goldfish is relatively large among ornamental fish, it is possible to raise goldfish normally without oxygen. As long as the density of goldfish in the fish tank is reasonable, the water quality is good, and there is no oxygen overnight, the goldfish will not die. However, if the density of goldfish in the fish tank is large, and the amount of dissolved oxygen in the water is maintained by constant oxygenation, and there are aquatic plants in the fish tank, then if the oxygen is suddenly stopped at night, the goldfish will also have the risk of dying from lack of oxygen.

Goldfish is a common species of aquarium fish that consumes a large amount of oxygen. For example, if you are raising tropical fish, even if the fish is stuffed, there will not necessarily be a lack of oxygen, but if it is used to raise goldfish, then it is only suitable for raising 4-8 goldfish with a body length of about 10 cm.

For example, the density of goldfish in the fish tank is very high, and it is maintained by continuous oxygen, and there is also a landscaping of aquatic plants in the fish tank, so once the oxygen is stopped at night, the consumption of the goldfish itself plus the consumption of plants will cause insufficient oxygen in the water, so that the goldfish will die of lack of oxygen. If goldfish are usually raised in a bare tank with low density of goldfish, and do not rely on oxygen to maintain the amount of dissolved oxygen in the water, then goldfish can still survive normally without oxygen at night.

In order to prevent the goldfish from being deprived of oxygen at night, the feeding time must not be chosen at night, and the digested goldfish consume a lot of oxygen. In order to prevent the lack of oxygen in the fish tank at night, the lights can be turned on for a period of time for the aquatic plants, so that the aquatic plants can produce oxygen to meet the consumption of oxygen by themselves and the goldfish at night.

When raising goldfish, it is best to put the tap water at home in the sun for 2-3 days when changing the water, so that the chlorine can be fully dispersed. If possible, you can put some chlorine removers, nitrifying bacteria, stabilizers when changing the water, and if you can put some special salt for fish, the water quality will be guaranteed to be very ideal, and you can generally change 1 3 cylinders of water according to the water quality for 1-2 weeks. In addition, it is also necessary to pay attention to the feeding of fish food, do not put too much at one time, and can feed in the morning and evening to reduce the death of fish caused by excessive intake.

Also, the change in water temperature should not be too large, too hot and too cold is not suitable for the growth of goldfish.

If the water quality is not good or the feed is strangled to death, if the goldfish is not fed properly, it is easy to die!

Raise ten goldfish without refilling, two or three days to draw the bottom, the fish feces are pumped, and it is completely OK to add some snapdragons to purify the water quality
