What is the reason why the fish are dying one after another?

First, the problem of water temperature difference.

Second, water quality problems.

Some cities have poor water quality, the water plant uses a lot of sterilization and detergent, the fish will be poisoned if they are not adapted, so there are skills such as drying water, bursting, breaking into the tank, in fact, the most easy to make fish poisoning is the chlorine in the water, new water with an appropriate amount of dechlorinated water is a good way to quickly solve the problem, but be careful not to excessive.

3. The accumulation of ammonia in fish feces reduces the physique of fish and causes chronic poisoning.

In fact, the accumulation of ammonia in fish feces not only causes the decline of fish physique and chronic poisoning, but also breeds a large number of various germs, which is one of the main causes of fish diseases, and there are several ways to solve the problem:

1. Choose feed carefully: The biggest problem with feed is that spoiled animal bone meal and carcasses are added during production, and do not choose rotten and fragrant feed.

2. Add salt: Adding salt to new water can inhibit the growth of some bacteria and provide salt for the normal metabolism of the fish itself.

3. Dosing: Fluoropinene acid is two grains per 100 catties of water, once a week, it is a broad-spectrum bactericide, low toxicity, and most of us have diarrhea to eat this.

4. Add nitrifying bacteria to decompose pollutants in water, feces and residual feed, and the bacteria lose nutrients.

5. Strengthen filtration.

Fourth, pay attention to hypoxia.

Fifth, choose a good fish.

My experience is that even if the fish does not have a disease on the surface of the body, as long as the eyes are sunken, do not choose, this kind of fish only has a lifespan of a few weeks at most, and the same is true for turtles. Because I have learned a certain amount of fish farming, my friends and I have all died of this kind of fish, and none of them have survived.

Pay attention to the quality of the water to be replaced, if there is too much chlorine in the tap water, it should be stored in a container for two days before it can be poured into the fish tank. In addition, the water in the fish tank cannot be changed to new water at one time, at most one-third at a time, so that the environment in which the fish live will not change too much.

Temperature problems: 1. The temperature is too low;

2. Keep a constant temperature of 25-28 degrees.

Water quality issues. 1. If the oxygen content is too low, add oxygen.

2. The water is too dirty.

The fish are sick.

Today, my mother bought a few crucian carp from the market and said that she wanted to make soup for me to drink. When I heard this, I danced with joy and shouted to my mother, "I want to see you kill fish."

My mother began to kill the fish, and I saw that she caught a crucian carp, but the crucian carp was not very obedient, and kept jumping around, and finally removed the scales and took out the internal organs. Put it in a basin. Just as my mother was catching the second fish, the fish that had been killed jumped to the ground.

I thought it was strange and asked my mother what was going on, and she said that although the fish was killed, its nerves were not dead, so he would move.

So where are the nerves of fish? Are its nerves innervated by the brain? I decided to give it a try.

I volunteered to say to my mother, "Mom, let me give it a try!" "I grabbed a fish and slammed its head on the ground, and he stopped moving, and then I easily removed the scales and took out the entrails.

Then put it in the basin, and after a while, the fish didn't move. It seems that its nerves are really governed by its brain. To prove it further, I grabbed another fish, and this time I cut off its head with a knife, and strangely, the rest of its body was still moving.

What's going on, isn't its nerves innervated by the brain? With this question, I quickly looked up the information on the Internet, and wanted to find out? It turns out that fish belong to vertebrates, and the nerves of spinal cord animals are divided into two types: central nervous system and migratory nerve.

Among them, the wandering nerve is a low-level nerve, which is controlled by the spinal cord, and there is a segmentation phenomenon in the spinal cord, each section has a pair of spinal nerves to contact with the outside world, and each spinal nerve innervates a muscle and **, and the spinal cord mainly plays a conditioned reflex function. Generally, after the death of the higher nerve center, the spinal cord can still function without severe damage. The muscles, internal organs, epidermis, etc., are connected by the terminus of the migratory nerves.

So, even if the head of the fish is cut off and the blood is released, the body will still shake.

Burst. The reason why the fish that I threw to the ground did not move was because its central nervous system and migratory nerves had slowly died between the time the fish fell to the ground and the time it was entrailed. <>

In fact, not only fish, but all vertebrates, including humans, will have this phenomenon. The lower the animal, the more tenacious it is. After the head of the snake is cut off, the head can still rely on the conditioned reflex to bite people, and there has been a report of a pit viper head being cut off to bite a person to death.

When it comes to the fish in the fish tank dying one after another, everyone knows that someone asks me what is the matter with the fish dying one after another? In addition, there are people who want to ask what is going on with the fish in the fish tank that keeps dying? Do you know what's going on?

Contagious disease! There are many kinds of infectious diseases, some of which are acute, and fish will die quickly when they get it. The fish raised died every three or five times.

Even if you have a filtration system, you can't filter out bacteria and parasites in it, so you get sick.

So hurry up and give the fish tank a complete elimination! with a solution. What's the matter with a fish farmer dying one.

Adding a little sterilization water and citrin to the water can prevent the occurrence of diseases.

Is it a new fish? If so, it may not be adapted to the water quality.

After a while, it will be fine, and the animals in the house will die one after another.

If not.

Then it is considered that it may be enteritis, and if it is enteritis, the fish will die one after another after adding fish to the fish tank. , buy some special ornamental fish enteritis medicine, do not use the medicine in the pharmacy (larger), stop feeding and observe for a period of time. Or try the old 3 things: change the water.

Warming up (around 30 degrees Celsius).

Add a lot of salt. The water is very clear, but why old dead fish.

Are the three elements of temperature, water quality, and oxygen ready? Do fish have rotten tails, etc.? Do you change the water frequently?

The size of the fish tank.

When the fish are underneath the water, there is no shortage of oxygen in the water! When swimming on it, it means that there is a lack of oxygen in the water and the water needs to be changed! If you have an oxygen machine, you can change it once a week! The main thing is why the fish die one after another.

Pay attention to the activity of the fish!

I also have more than 20 fish, and I haven't died for more than 1 year! It should also be raised according to the species of fish.

The fish tank should be clear and clean in advance, and the water in the fish tank is dried in the sun for 1-2 days.

The goldfish you bought should not be put into the fish tank in time, you should put it in the fish tank with a plastic bag for 3-5 minutes, let the fish adapt to the water temperature of the fish tank, and then open the bag after getting used to it, and put it in the fish tank with the water in the bag.

After putting the fish in the fish tank, add it to the fish tank and be aware of the bacteria contained in the water in the fish tank and in the plastic bag. How to prevent cross-infection with new fish in the fish tank.

Frequent exposure to the sun can also kill bacteria, but can not be exposed to the sun, goldfish are not suitable for long-term life in the sun.

Originally, my guppies were like this, one after another died, I don't know what the reason, after knowing that many of them died, when I saw that there were only a few left, I fished the normal looking fish into another tank, and then waited for the other dying fish to die, and then washed the tank with salt, and then fished those fish in, and then found some fish of the same species to fish in and mix together, and change the water once a day. Attention! The temperature of the water is important!

I must firmly believe that they should die one by one, not together Then, your fish may be sick, how unfortunate it is, if you want to raise fish, go to the professional literature, and the dying fish will live with salt.

That's all it takes to die one after the other with my fish? Related content, is about my fish dying one after another, what's going on? shared. After watching the fish in the fish tank die one after another, I hope this will help everyone!
