Why did the little fish I just buy lie on the bottom of the water and don t move, as if it was dead?

Every time the fish is bought home, because it is very weak when transporting, and the sudden change in water quality makes it worse, and it is easy to die. The correct way to deal with it is:1

Without untying the plastic bag, place the bag in the tank and let it float on the water. Generally, it is 10-30 minutes, if the temperature difference is too large, it can be appropriately extended, so that the temperature of the plastic bag water and the water in the tank.

until the temperature is the same; 2.Open the plastic bag, pour out a part of the water, then pour the water in the tank into a part of the bag, tie the bag tightly, and let it stand for five minutes; 3.Repeat step 2 several more times; 4.Remove the fish and put it in the fish tank, and pour out all the water in the bag, do not pour it into the fish tank.

There are three possible reasons why the goldfish lie on the bottom of the tank and do not move: normal physiological state, stress response or abnormal pathological state.

1. Normal physiological state - fish are vertebrate animals 5261, need to sleep to eliminate the fatigue of the nervous system and limbs, if they are still asleep, of course, lie at the bottom of the tank and do not move.

2. Stress response - a new tank or a new water change causes a certain pressure, and the fish will show lying at the bottom of the tank when it is not adaptable, and it will be good to adapt to it after a period of time.

3. Abnormal pathological state - the decline of physiological ability caused by various diseases 1653 diseases, not liking to move, and being calm at the bottom of the fish tank. It is necessary to distinguish **symptomatic**.

If you lie on your stomach at the bottom of the tank and sometimes swim wildly, it means that you are in a very poor state and may be about to die. It is best to change the water in large quantities and test the water quality at the same time.

1. Select a fish tank.

The choice of fish tank is very important, not only according to the number of goldfish to choose the size of the fish tank, but also to ensure that the density of fish is reasonable, the general fish tank should not raise too many goldfish, to deposit the number of fish and the size of the fish tank is reasonable.

2. Select water quality.

Leave your tap water in the sun for a few hours before you can use it to raise fish.

3. Choose feed.

The food of goldfish is mainly goldfish feed, and some noodles, rice, insects, etc. can also be appropriately fed.

4. Choose a decoration.

After putting the common and beautiful stones in the sun like tap water, they can be placed in the fish tank, which is not only beautiful, but also conducive to the growth of goldfish.

5. Change the water. The water in the tank usually needs to be changed once a week or so to ensure that the fish will not die.

To raise goldfish, place the aquarium near the window and in a sunny place. It is necessary to pay attention to the stocking density, according to the size of the container, reasonable arrangement, rather less than more. Because the indoor air circulation is not large, the water is easy to be turbid, which is easy to cause goldfish to die due to lack of oxygen.

If you have an air pump, you can raise more, and if you find that the goldfish has a floating head, you need to open the air pump to oxygenate, especially at night, you need to be oxygenated.

6. The bait used in household fish farming is the most ideal for live fish and insects, and the water quality is not easy to be damaged. Now there are live fish and insects on the market**, but it is also troublesome to buy them every day. For the dried fish and insects sold in the market, you should choose relatively fresh and loose particles to feed the fish, and do not buy old and moldy dried fish and insects to feed.

Artificial pellet feed is better to use full price feed with complete nutrients, and it is sold in the market. In order to keep the water pure, the amount of bait should be strictly fixed and quantitative, usually 1 to 2 times a day is appropriate, each time the amount of bait is appropriate to eat within half an hour, and the bait should not be fed too much.

6. Choose healthy goldfish.

Healthy fish swim in the middle and lower layers of the water body, foraging for food, swimming naturally and leisurely, and their tail fins are clear and elegant.

7. Don't rush into the tank after buying the goldfish home.

Put the plastic bag containing the fish into the fish tank for 10 to 20 minutes and then open 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 goldfish can gradually adapt to the water temperature and water quality. If there is a light, turn it off. In the dark, the fish are quieter and less easily frightened.

8. Do not change the temperature of the water drastically.

When buying fish, you should pay attention to the water temperature of the aquarium store and the water temperature of your fish tank, and the deviation should not be too large, generally within 4 is allowed.

9. Do not change the water too much at one time.

Fresh water must be stored for a day or two. The purpose is to remove some of the chlorine from the water and also to bring the temperature of the new and old water closer.

Why did the little fish I just buy lie on the bottom of the water and don't move, as if it was dead?

Maybe this little fish is really dying, or the weather is too cold and the water temperature is too low to make the little fish not very active.

Buy a fish tank heating rod and heat the water to about 25 degrees, and it may be lively.

The fish you just bought can not be directly put into the container at home, you should first put it in the water with a plastic bag, wait for the same internal and external temperature, and then slowly put the water in the tank into the plastic bag, pour out half of it when it is full, repeat it several times, about 1 2 hours later, and then fish the fish into the fish tank.

Are you willing to move blindly in the winter, I don't want to move anymore.

Summary. Goldfish can be unheated in the winter, but they are definitely more susceptible to death than normal temperatures, and there is wear and tear.

Why do fish stay motionless underwater.

The water temperature is low, and there is a lack of oxygen.

Turn on the heating rod and oxygen pump.

Let them take their time.

Turn the heating rod on to 28 degrees and it's OK

That's it.

Completely still.

You touch him and try it.

Motionless. That means he's dead.

When the temperature is low, it is not heated and oxygenated, and goldfish are indeed prone to death.

But why is the other one not afraid?

Individual. Physical fitness is not the same resistance to these.

Goldfish can be unheated in the winter, but they are definitely more susceptible to death than normal temperatures, and there is wear and tear.

But when the fish die, shouldn't they all float on the surface?

No. Float up only partially.

Also, if it doesn't float, it means that it has just died.

It's not a dead copy, if it's dead, it will float on the surface of the water. It may be a lack of oxygen, the oxygen density at the bottom of the water is higher than that on the surface of the water, and it is better not to change all the water to new water when changing the water.

The ** of fish is composed of epidermis and dermis, the epidermis is very thin, composed of several layers of epithelial cells and germinal layers, the epidermis is rich in single-celled mucus glands, which can continuously secrete viscous fluid, so that the body surface forms a mucus layer, lubricates and protects the fish body, such as reducing the friction resistance of **; Improves athletic capacity; Removes bacteria and dirt that adhere to the fish's body.

I am observing the new environment to see if there is any danger.
