Hello, probably white spot disease :

White spot disease is caused by the invasion of the protozoan melon worm into the fish** or gills. Its melon worm is a type of ciliate among the protozoa. Microscopic examination of the adult worm has a large horseshoe-shaped nucleus.

Juveniles have large nuclei that are round, oval, or rod-shaped. The body of the insect is soft and malleable, and the form is changeable. This disease is one of the most common diseases in ornamental fish, and its pathogenesis is characterized by rapid infection, wide epidemic and great harm.

Visit Gemdale and pay attention to people's livelihood.

There is no heating device. There's no way to keep the water temperature constant.

Malachite green can also be white-spotted. It's just that the concentration must be mastered well. It's too good, it's bound to die.

If you have a low temperature there. You can also. I lower the temperature to around 8 degrees Celsius. A few days later. Change the water again.

At the same time, malachite green low-concentration medicinal baths.

Your fish isn't tropical, is it? Goldfish don't like hot water, it prefers colder water. It's not good to be hot.

Add some medicine to the water to cure small fish diseases. For example, yellow powder, my fish tank uses yellow powder, which will not poison the fish, and the amount is not too large. Good luck to your little fish soon**.

Change the water first and add a pinch of salt!

It's the fish that gets white spot disease.

The so-called white spot disease, also known as white spot disease, is a common disease of fish in winter. The main symptoms are: the head and tail of the fish are swinging, the diet is not sluggish, the corner of the fish tank is lazy to move, and the fish body and fins have small white spots.

The reason is that the indoor temperature fluctuates from high to low, resulting in the water temperature of the fish tank being hot and cold.

When the fish is found to be sick, it should be immediately removed for isolation, and the white spots on the sick fish should be broken with tweezers, removed, and then put into the salt water for bathing. After washing, it is reared separately and sent to the fish when the fish body ** is sent to the fish. If all the fish in the tank suffer from this disease, you can use red mercury drops in the tank, put a drop of red medicine in every kilogram of water, and increase the water temperature to 27 degrees Celsius.

When using the original tank water**, at the same time darken the fish tank, and wait for the fish to heal, and then gradually change to new water until the water quality becomes clear.

The main causes of white spot disease are as follows:1The fish was already white while it was still at the merchant's.

2.It was caused by the cold on the way home after buying it.

3.When the fish was brought home and entered the tank, there was no water, and the difference between the water temperature in the bag and the water temperature in the tank was too large.

4.Water quality and temperature**.

If it's 1, you can only pick it carefully when you look at it, basically ordinary fish, and the fish dealer will let you pick and catch it yourself.

If it is 2, try to buy tropical fish when the weather is warm, which is why many ** stores do not send live fish express when the weather is cold, it is too easy to get sick or even die.

If it is 3, every time you buy a good fish, first put the bag in the fish tank and float for a while, so that the water temperature in the bag slowly remains consistent with the water temperature in the tank, and pour out the water in the bag every 10 minutes, and replace it with the water in the tank, each time you change about 1 4, so that the fish has a buffer period for the water in your tank, the change is too great, and the fish with a good physique will be uncomfortable.

If it's 4, usually a stable water environment will not get white spots, if the temperature in the tank can always maintain a balance of about 25 degrees or above, then it is unlikely to get white spots, but if you do, it will be very fierce.

After getting white spots, if possible, isolate them first, and white spots will be contagious. Raise the temperature to more than 28 degrees, add methyl blue according to the amount of instructions (sold in fish stores, very cheap, only 5 yuan a bottle, and the medicinal properties are mild, it does not hurt much if you put a little more) for a medicinal bath, soak for 20 minutes to half an hour, and persist every day until it is cured. If it is ferocious, methyl blue is sometimes not strong enough, you can replace it with a medicine such as white spot net, but you should be cautious when putting it away, because these drugs are more violent, and if you put too much, you will give your fish a ride...

White spots may be parasites in the fish, and generally the water temperature can be cured by adjusting the water temperature to about 30 degrees (the temperature cannot be lower than 28 degrees). If it really can't be cured, add some methyl blue or yellow powder. Large temperature differences when raising fish can be the cause of white spots.

Sick ... It may be white spot disease or powdering, a little unclear, you can check ** to compare.

You can add a little bit of salt with large particles, and then add warmth, and don't feed it for 3 to 5 days.

Don't use drugs, bask in the sun, the water basin should be very transparent and transparent, put salt, put it, the water temperature should be higher, and turn on the air conditioner. Never use medication !!

According to my experience, adding salt, adding yellow powder, and taking medicine continuously for a week is fine, and do not feed during this period.

Is it an unfinished disease, it is estimated that someone in your tank is polluted, turn the tank with potassium permanganate sterilization, and then inject pure water and try again.

Rotten fin disease is caused by infection with B. brevid. The fins are broken and discolored, and there are foreign bodies in the rotten places, or the transparent fin leaves are whitish, and the white gradually expands;In severe cases, the fins are mutilated or cannot be stretched. The epidermis near the fins of the diseased fish falls off and is grayish-white, and in severe cases, the fin strips fall off, the muscles are exposed, and they do not eat, resulting in death, and this disease is epidemic in summer.

Solution: Put 5-8 tablets of oxytetracycline in 100 kg of water to soak and disinfect to prevent infection with this disease;Dip with gentamicin and place 2 sticks in an aquarium of 100 cm x 50 cm x 35 cm. Put nitrofuracillin powder gram in 100 kg of water for immersion and disinfection, and the condition can be relieved after multiple medicationsA low concentration of potassium permanganate solution can be used to sprinkle it into the fish tank to achieve the purpose of immersion and disinfectionPutting 3-5 tablets of dysentery in 100 kg of water and soaking the diseased fish for 30 minutes can also achieve a very good ** effect.

This is called white spot disease, which occurs more often in late autumn and early spring when the water temperature is lower, and tropical fish of the carp family and cichlid family are more susceptible to infection.

**The method is very simple, as long as the temperature is raised to 30 degrees, the small melon worm (small white spot) will die.

Medication is also acceptable.

It's not good for fish though

Wipe off the film by hand, change the water in the independent tank, put some raw salt concentration to be enough, pay attention to observe and then change the water. There will be a change.

If the fish is sick, change the water and put some anti-inflammatory drugs.
