My goldfish is sick! What can you do? Thanks!

Fish can only be healthy and less sick if they live in a good water environment. The living environment is very important for all living things, and everyone knows that a newly renovated house needs to be vacant for a period of time before it is suitable for habitation. People who work in chemical plants can retire at the age of 45, which fully demonstrates the importance of the living environment to people's health.

Some harms do not manifest themselves all at once, but have a process of accumulation. If one day you find that the fish that used to be active have become listless, anorexic, or sick, it usually means that there is something wrong with the water in the tank, which usually starts with the fish with a weak constitution.

The quality of the water in the fish tank is really important to the fish, and the relationship between the fish and the water is like the relationship between people and the air. Imagine what it would be like for a person to eat and pull in a room without an exhaust fan or flush toilet. If you are in a room with an exhaust fan and a flush toilet, the situation will certainly be satisfying.

So what is the "exhaust fan" of the fish tank, that is, to change the water. Even if an intact ecosystem is established in the fish tank, it is necessary to replace the water in the tank frequently and as necessary, and to increase the activity of the water by replenishing it with new water. As for the "flush toilet", there are two kinds: manual and automatic, manual is to use a straw or sand washer to clean up the solid waste at the bottom of the tank by hand, and the automatic is the automatic extraction function provided by Yongqing filtration.

On the one hand, the Yongqing filtration system provides a large area for cultivating nitrifying bacteria in the tank, which can decompose and transform fish feces in a timely manner and maintain the stability and clarity of water quality. On the other hand, it is actually the automatic "flush toilet" of the fish tank. So that you can enjoy the fun of fish farming more easily.

Subcutaneous congestion, soak with permanganate A, vitamin B2, salt, diluted solution for half an hour, once a day for two or three days, it can be solved, the water quality of the fishing tank is kept clean, but do not change the water too frequently.

Change the water. It must have been caused by the water breakdown.

As for the cause of bad water, it is either that the water has not been changed for a long time, or that the density of fish is high and causes a lack of oxygen.

Always change the water and pump and stop eating.

It's congested, and it's best to put some yellow powder.

White spot disease: This disease is caused by protozoa, the pathogen is called white spot worm, which will penetrate deep into the cells of **, carry out asexual reproduction, and form small white punctate cysts. Goldfish with this disease are covered with white spots all over the body, each white spot cyst contains many young white spot worms, white spot worms absorb the nutrients of the fish body tissue and grow up and increase the number, and then break out of the sac, swim into the water, and then return to the fish body to invade**, forming more small white spots.

In the early stage of the disease, the sick fish will rub the hard objects with their bodies in the hope of removing the nasty pathogens from the body, and if they do not ** immediately, the body of the sick fish will quickly be severely damaged and die. When the white spot worm invades the fish, the drug** does not work, and only when the small white spot worm reproduces in the fish and the new individual swims into the water, the agent can kill them. **The method is to use a percent concentration of malachite green solution, soak the diseased fish for many days, until the small white spots completely disappear, the toxicity of the malachite green solution is very strong, do not use excessively, otherwise the goldfish will also be poisoned, or use the commercially available Sera white spot agent, American white spot treatment, queen whale white spot treatment, AZ00 parasite**.

Some aquarists asked, the white spots disappeared after the whole tank was applied, and they would appear again after a week or two. Why does this cycle go on all the time? This is also a problem that goldfish people can often encounter, the general drug can directly kill the adult worm, but the problem is that the drug can only kill the adult, and its larvae, can hide in the skin of the fish, the medicinal properties can not go deep, so it will repeat.

Some books say that raising the water temperature to 30 degrees can remove the white spots, but for goldfish, this temperature is too high, even if the white spots are cured, it may also cause other problems. It is recommended to use more sunlight at the same time as taking medicine, pay attention to the same water temperature when changing the water, and insist on using some water purifier every day after the white spots disappear, and the white spots will be completely **.

Raise fish, first raise water.

The water quality of your fish tank is not good, and from the picture, even this relatively durable single-fin goldfish is infected, so imagine how bad your water quality is.

You need to use some nitrifying bacteria, plus water circulation, to cultivate good water quality.

Each time you change the water, replace it by half.

Add white spot net and take the drug for 4-5 days, that is, it is good.

When you are sick in this situation, to be honest, you are not optimistic, and you must be mentally prepared.

Look at your description of the current external symptoms of the fish is the loss of drift, rotten fins, how to cause it is not easy to say, what can be done at present is to maintain good water quality, temperature, add less salt, if you want to use medicine, it is recommended to use yellow powder (broad-spectrum antibacterial drugs, very effective for external injuries) medicated bath, 2-30 minutes a day, the dosage can be mastered in the water color is slightly yellow. The medicinal properties of yellow powder are relatively mild, and other medicines such as potassium permanganate and malachite green have good effects but are too toxic, and it is estimated that the current situation of fish is unbearable.

You can also feed some live food, which can enhance the physique of the fish and help the body recover.

It is a problem with the swim bladder, a very common disease, mostly occurs in the summer (when changing the water), once the swim bladder is injured, it is difficult to recover, can not **, the side swim sometimes improves and can eat to maintain the state of survival, once, after the development of the back swimming, it can not eat, in order to consume the energy in the body to maintain, it also needs to maintain a stage, not too long, and eventually go due to hunger.
