Our aquarium fish in our house always die and don t know what s going on?

Water mixing has nothing to do with the quality of the water. The amount of harmful substances in it has increased. Change the water regularly.

And it's quantitative, every time. You can't stop changing the water just because it doesn't mix. Also you look at your temperature, is it too high.

Change one-third to one-fifth of each water change, don't change more. The water is going to be sleepy and changing.

First of all, I want to say, your fish tank is so big, I like it so much, I have no place to put it in my house.

One, do you have filtration, and two, how often do you feed.

Third, carefully observe the body of the dead fish, there must be a problem, the fish will not be inexplicably warped, there must be a reason.

Fourth, the breeding density of your fish tank is about the same as a month, but what kind of water do you get?

Fifth, your fish tank can be filled with oxygen without flushing

If you still don't understand, you can ask me again.

To give the fish a large space, change the water about once a week.

If there is a dead fish the first time, the fish tank should be cleaned and disinfected when the fish is re-released the second time to prevent the remaining germs from infecting the subsequent fish.

On the other hand, every time a new fish is put into the tank, the new fish should also be disinfected with medicine (soaking in light salt water is also acceptable) to prevent the introduction of new germs.

Carp should still be relatively easy to raise.

Go to the forum for raising koi fish, there are many things to learn.

If the feed does not expire and deteriorate, the fish will die after feeding, often if the feed is too much. Don't feed too often, either. Ornamental fish should be fed in moderation, once a day or once every two days, and more fish are easy to break, get sick and die.

At the same time, excess feed will affect water quality, accelerate the rate of water deterioration, and also have an impact on fish.

<> many novices always die when raising ornamental fish, and may not change the water for a long time, so that the water is hypoxic, deteriorated, and caused by bacteria, it is recommended to change the water for ornamental fish regularly to keep the water clean and also need to increase the oxygen in the water. It may also be caused by frequent water changes, and it is generally enough to change one-third of the water every three days.

The fish in the fish tank at home are always dying, most of them are breeding technology problems, and the unnatural death of ornamental fish mainly has the following factors:

1. The water temperature exceeds the tolerance range of the feeding object or fluctuates violently in the range;

2. The pH value of water quality exceeds the tolerance range of the object of feeding and raising or has violent fluctuations in the range;

3. The hardness value of the water exceeds the tolerance range of the feeding object or has violent fluctuations in the range;

4. Improper trapped tap water, and the residual chlorine exceeds the standard;

5. The feeding density is too large, resulting in hypoxia;

6. Improper setting of the filtration system or mismatch of treatment capacity, resulting in ammonia nitrogen and nitrite poisoning;

7. Nitrate and phosphate poisoning caused by poor nutrient control (only for marine fish);

8. Fighting injuries caused by conflicts between polyculture breeds;

9. Pathogenic bacteria and parasitic infections.

For newbies who are old and dead fish, give the following advice:

1. Don't be too provincial in feeding equipment, testing reagents, etc.;

2. Don't be too greedy to raise too many quantities at the beginning;

3. Carefully understand the requirements of each breed raised.

The fish in the fish tank are always dying, it may be because the fish lack oxygen, or Nian Liang or hungry, and there may be a young man who may die because of the excessive feeding amount button, of course, it is not excluded that the fish is sick and dies.

1. Reasons.

1) Hypoxia. 2) The water quality is not good (turning white or green), causing the fish to get sick.

3) Do not use tap water directly, but change the water with water that has been trapped for at least three days.

4) A water change can not be more than one-third, let alone a full water change, the full water change fish will not adapt to the new water, gather and then die.

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.

6) The goldfish may be strutted to death, and the goldfish does not know that it is hungry.

2. How to raise goldfish.

1) In addition to eating artificial bait, I prefer to eat bloodworms, snakes, jumping insects, etc., to ensure that the bait is fresh, and the spoiled ones can not be fed.

2) Feed 1 time a day, feed at a fixed time, goldfish do not know hunger, so each time feed eighty percent full, feeding within five minutes is appropriate. Fish can grow healthily and keep the water fresh for a long time. If you feel that feeding once is not enough, you can also feed it twice, but take the form of eating smaller meals and more meals, feeding five minutes at a time, and once in the morning and once in the evening.

3) Goldfish is a cold-blooded animal, so it is not afraid of cold, and the water temperature can grow faster at 20 degrees, and the minimum can not be lower than 5 degrees. But since you keep it indoors, I believe that the temperature should not be very low, and it is fine if the water does not freeze, but try to keep the water temperature constant, and it will definitely catch a cold if it is hot and cold.

4) You can't use tap water directly to change the water for fish, because tap water contains too much chlorine, and the tap water can be used after three days (called trapped water).

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, so that the water can be changed only a little, and the water can be kept clean and the oxygen 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.

In fact, ornamental fish are very good to raise, novices will definitely encounter some setbacks, I have been raising for many years, now, as long as I want to raise, there is no fish that I can't raise, if the landlord is really interested, it is recommended to buy some books to see, this is indeed a kind of fun.

Possible water quality problems The water for fish farming should be put for 3-4 days before it can be poured into the fish tank New fish can not be put into their own fish tank immediately after buying it It is necessary to let the new fish adapt to the temperature in the city and then put it in the fish tank When putting in the new fish, you should put some coarse salt sterilization (the large kind, not edible salt) The fish has just been bought Don't feed it within 24 hours And when you buy fish, you should take a closer look at whether the fish you bought is injured If the fish you buy back are dead, you should take out the dead small fish in time Put some bactericidal medicine or put some coarse salt about that, the most important thing is to take care of them carefully, hehe, I have guppies, I don't know what kind of fish you have.

Change the water often, don't raise too much at a time.
