The fish raised in the fish tank at home have died a lot in the past few days, and what should be pa

The key to raising good fish is filtration, and filtration is mainly to filter fish feces, and the toxins in the water are produced by fish feces. The fundamental purpose of fish filtration is to remove the ammonia poison produced by the decomposition of fish feces in the water body. This can only be done by biological filtration, and nitrifying bacteria is a kind of bacteria that specializes in ammonia in fish feces as nutrition, which can convert ammonia poison into harmless substances for fish, so that the water body will be non-toxic and the fish will be healthy and less sick.

If there is a lack of eczematic area of nitrifying bacteria in the tank, there are very few nitrifying bacteria, and the fish feces can not be treated in time, the ammonia content of the water body is high, and the fish will live in the water body with ammonia poison for a long time, and the physique will slowly become weak and it is easy to be attacked by the virus in the water. Just as there are always various viruses in the air in the space where human beings live, people who are healthy are not susceptible to viruses, and people who are weak are prone to diseases. Therefore, timely removal of ammonia produced by fish feces is the fundamental guarantee for fish health and less disease.

Yongqing filtration understands that this filtration system has the function of automatically cleaning fish feces, which will help.

Pay attention to the water temperature, change the water frequently, oxygenate, and dispose of excess fish food in time, otherwise it will affect the water quality and is easy to rot.

Filtration, oxygen, water quality, add some dechlorination medicine when changing the water, buy a water pump that combines filtration and oxygenation, basically fresh water can be fed.

Reduce feeding, don't toss established nitrification filtration systems as much as possible, increase the frequency of rehydration or water changes, don't add new fish, and oxygenate appropriately.

If it is indoors, you have to control the room temperature, and if the temperature is high, you have to increase the water capacity to give it a more relaxed environment.

The fish in the tank always die in the summer, which may be caused by poor water quality, when the temperature rises, the bacteria in the water grow faster, and the water quality deteriorates faster. In addition, when the temperature is high, the oxygen in the water will also be lost faster, and it is easy to suffer from hypoxia, so the keeper needs to fill the tank with oxygen.

In the hot summer weather, bacteria grow faster than usual, and if too much food scraps and excrement accumulate in the fish tank, it is easy to pollute the water quality, and the fish are more susceptible to bacterial infection, resulting in death. Therefore, the keeper should clean the fish tank frequently in the summer.

When the temperature is high, the oxygen content of the water also decreases, and if the keeper does not add oxygen to the tank or change the water, the fish are prone to hypoxia. It is recommended that the keeper regularly fill the tank with oxygen or install an oxygen pump during the summer when the temperature is high.

In addition, the fish may also die, when the temperature is too high in summer, the desire to eat will be reduced, if the keeper feeds too much feed, the fish may die due to indigestion, so it is recommended that the keeper feed the fish with small meals and frequent meals.

Why do summer fish die?

Summer is the season when fish grow most rapidly and are most active. But at the same time, due to factors such as high temperatures, hot temperatures, and unstable summer rainfall, the fish tank environment has also become more complex and difficult to control. Therefore, summer fish farming needs to be extra careful, and the following are the problems that are prone to occur in summer fish farming, which are roughly divided into four sub-headings: water quality problems, oxygen problems, feed problems and disease problems.

1. Water quality problems

In summer, the water temperature is high, the dissolved oxygen content in the water is low, and the rainfall in summer is unstable, and the water quality is easy to fluctuate, so the water quality problem is a major difficulty in summer fish farming. In summer, fish farming should pay attention to regularly changing or cleaning the filter. In order to maintain water quality, feeding management can be strengthened, the number of aquatic plants can be increased, and plants can be used to absorb some waste materials and socks to resist carbon dioxide.

At the same time, the use of water treatment pulsators is also a very effective method.

2. Oxygen problem

The most feared thing about fish farming in summer is the problem of "lack of oxygen". Due to the high temperature of the water, the oxygen content in the water will decrease, so it is necessary to consider increasing the amount of oxygen**. Methods such as surface oxygenation, increasing the power of the water pump to amplify the input of oxygen, and increasing the number of aquatic plants in the water can be used.

3. Feed problems

In summer, the metabolism of fish is accelerated, the hunger is reduced, the amount of food eaten increases, and the amount of feed residue also increases, which affects the water quality and may also lead to food accumulation. Therefore, feed once a day in the morning and evening, and control the amount of each feeding.

4. Disease problems

In summer, the temperature is high, the rainfall is abundant, and the environment of the fish tank changes frequently, which can easily cause stress and disease in the fish. Therefore, it is important to observe the fish more closely. If you find that the fish has no appetite, the surface of the body is black, white spots and other abnormalities, you need to deal with it in time**.

Summary

In short, summer fish farming requires mastering some skills, such as paying attention to water quality, increasing oxygen, appropriate amount of feed and paying attention to disease observation and so on. In the usual fish farming, pay attention to these details, so that your pet fish can be better protected and maintained in the summer.

The fish in the fish tank have been raised for a long time, why do they die.

The density of the fish is too great, there is a severe lack of oxygen, and the weak fish will die. Fourth, the water quality is too poor, turbid, and the moss is flourishing. It is recommended to change one-third of the water every three days, and note that the new water should be left for a day first.

5. Improper feeding and overeating. 6. Some objects in the fish tank are inappropriate, such as coral stones, which are sea objects and are not suitable for fresh water tanks.

Because the weather hot water temperature rises, the fish are easy to die.

It should be easier to raise fish in the summer.

The most important thing is the water temperature.

In summer, the temperature is high, the oxygen content in the water is low, the goldfish eat a lot, eat a lot, and the analysis is more, the water quality is very easy to deteriorate, and the goldfish are easy to die; In winter, oxygen in the water is not a problem, goldfish are not easy to die, but the water temperature is low, goldfish are not moving, and the beauty of goldfish is not as good as spring and autumn, but if it is kept indoors, as long as the water temperature is above 5 degrees, the feeding and activities of goldfish will still be normal, and the ornamental nature is still very good.

1 Feeding environment, you can choose a fish tank or fish pond to feed, but keep in mind that goldfish are cold-water fish, the demand for oxygen is great, enough space and dissolved oxygen is the key to ensure the healthy growth of fish.

2 Water quality, because goldfish have a wide range of adaptation to water quality, the water quality in most parts of China is suitable for raising goldfish.

For those of us who are aquarium fish lovers, "raising fish first and raising water first" is a wise saying, and it is convenient to raise fish after raising water. Goldfish like green water, if goldfish live in green water, grow much faster than clear water, green water breeding should pay attention to "back to clear water".

3. Feeding, for the fish that you just bought, don't rush to feed, and feed it after 1-2 days. Most of the domestic goldfish are fed feed, and the feed is not as good as live bait, so we should often feed some fish insects, earthworms, etc., which not only fish love to eat, but also help fish color. It is best to soak and disinfect the live bait with potassium permanganate, and then wash it before feeding the fish.

Goldfish can be fed once or twice at a time, without excessive feeding. Live bait can be fed more, and the fish will eat their own proportions and will not be full.

Goldfish will survive because they eat artificial feed, and the feed will swell when exposed to water. After the fish eats the feed, the feed swells in the stomach, so the goldfish survives.

If you can't grasp the amount of feeding, you can feed the feed equivalent to the size of the head of the fish 1 2, so that not only the fish will not be hungry, but also not easy to die. When you can grasp the amount of feeding in the future, you can increase or decrease the amount of feeding yourself.

If the fish are sick, they should be fed less or at a later rate to avoid waste or water quality.

4. Change the water, generally you should change the water about once a week, and it can be longer in winter. Generally, it is enough to change 1 to 3 at a time. Carry out a full tank water change every 1-2 months.

If there is a sudden lack of water or the water is easily dirty, you should immediately change the water completely and adjust the water change time according to the actual situation.

The new water that has been cooled must be used to change the water, and the water temperature cannot be plus or minus 2 degrees related to the water temperature of the original tank.

In addition: in order to prevent fish diseases, we should prepare some commonly used medicines, so as not to need them from time to time, generally the following drugs can ** most common fish diseases, you can use different drugs according to your needs.

Salt: It will be available at home, which can be disinfected and can also prevent and control a variety of ** or gill protozoan parasitic diseases, water mildew and bacterial fish diseases.

Furazolidone (also known as dysentery): It has a broad-spectrum antibacterial effect, is most sensitive to Escherichia coli and dysentery bacilli, and is effective against gram-negative bacteria.

Potassium permanganate: disinfect fish tanks or utensils. Effective against parasitic or bacterial diseases. When soaking fish, the concentration should not be too large, because potassium permanganate has a certain corrosiveness and is very harmful to the gills.

1.Looking at the picture, you don't have a big fish tank, how can you raise more than 500 fish, high-density breeding is easy to die;

2.No matter what fish tank, the water must be changed, but it can be changed less when the water body is large and the amount of fish is small;

3.The difficulty of raising small tropical fish is similar, mainly to maintain water temperature and water quality, eat small meals often;

Moonlight and lantern fish are very lively, but not too much, each fish has to have a little space.

Maps, parrots, phoenix tails or something, more than 500? Are you buying small tropical fish? Don't change the water for a long time, even if the filtration is very strong, the water looks very clear, but the water quality will get worse and worse, there are many substances that cannot be seen, but you don't change the water, resulting in greater and larger concentration, the hardness of the water will only get higher and higher, and small fish have high requirements for water quality!

Generally, small tropical fish require hardness for water quality, and the pH requirements are relatively high, although after the water is fixed, as long as it is not powerful, there is no problem, but you are getting harder and harder, and it is strange that you can try to breed three-lake cichlids, this kind of fish like hard water to buy fish according to their own situation

There is also the filter pump 24 hours can not be stopped, will affect the nitrifying bacteria.

Your fish tank is really not big, and it's not high-end.

More than 500 are too dense, raise a little less.

Lose those fake flowers and grass.

If you don't see the heating equipment, don't keep tropical fish.

A few questions for your own reference: the fake stone and fake grass itself is poisonous, the density of more than 500 fish is a bit too competitive + infectious diseases are inevitable, and there is no problem with the fish themselves.

Raise water first, put some small grass carp fry and then raise others! The survival rate of phoenix tails is very high!

Temperature (including fluctuations).

Oxygen pH salinity (change the water regularly).

Try some guppies and traffic lights first. Raise it for a week and put something else.

Found a key time, more than 500, is the density too great??

There is a lot of knowledge in fish farming, and each fish has different requirements for light, water quality, oxygen, temperature, and food.

How big is your fish tank? There are more than 500 tropical fish, and I estimate that there will be at least a huge tank more than 10 meters long and several meters wide to raise them. Your house is not an aquarium, so there will be such a big fish tank??

You still raise some goldfish, koi, such fish, put it directly in the fish tank, no need to heat, just feed the fish feed. Very easy to raise.

Raise some more oxygen-tolerant fish, such as brontosaurus, arowana, arhat, loach can be.

You can raise koi, not necessarily your fish tank is very high-grade fish will live well, if you think so, you are wrong, there is a good fish tank and fish tank equipment is good, but if you raise fish water quality is not good, the fish you choose is not healthy, your feed is not good, daily management is not good, no matter how cow's fish tank is in vain, if a person is better than you in the later stage, a canned bottle can feed fish.

It is recommended that you buy guppies, black maries, white maries, glass cats, store-sold small scavengers (nice cm, golden yellow) red nose scissors, etc... Died because there were too many species, too many fish, not being fed, or not enough temperature (did your equipment heat up?). By the way, you get under the fish you raise.

Raise koi fish.

Or grass gold. Ruthless or peacock. Peacocks: You can also breed on your own, which is quite fun, suggest you tell me how big your tank is.

I advise you not to raise fish anymore. Turtles are the least likely to die, and this is the case in my family, where fish often die.

As long as the water quality is maintained, any fish can live well.

Fish farming is very troublesome, there are many reasons for death, and I can't answer them in such detail.

The forty-seventh chapter of the book of life and death of the double cultivation of the eagle Song Gongming a dozen Zhujiazhuang.

Raise the kind of fish that eats, or koi fish.
