What s the matter with white lumps on the fish

At first, the parasitic larvae are not obvious, and the body surface is white, and the white spot symptoms are obvious when a cyst is formed on the body surface of the fish a few days later.

Prevention and control methods: extend the drying period of tap water and let the water "cook" through.

Use gram mercurous nitrate, dissolve in 10 kg of water, soak the diseased fish for 10-15 minutes, note that because mercurous nitrate is highly toxic and corrosive, the liquid should be placed in a plastic basin, not a metal container. (Mercurous nitrate is very toxic, pay attention to human and animal safety when using).

You can also choose a concentrated red mercury solution, put it in 10 kg of water, soak the diseased fish for 15-30 minutes, and use it 2-3 times in a row, which can effectively kill the insect body.

Use a percentage 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 excessive dose, otherwise the goldfish will also be poisoned, or use commercially available white point agents, extra-parasitic agents**.

Tropical fish can use a heating rod, the water temperature in the fish tank rises to more than 30 within 2 3 days, and the melon worm can get out of the fish body by itself, and use the siphon to suck out the dirt and pathogens at the bottom of the tank, and add an appropriate amount of new water. (Note: Goldfish can withstand temperatures above 30 degrees, you need to pay attention to cheering, when the temperature is 3 degrees, the oxygen content in the water is very small).

My prevention and control method: add 10 ml of red syrup (red mercury) to 20 kg of water, and then put the sick fish into a medicated bath for 20 minutes, once a day, for 4 days.

There is white flocculent on the fish, which is caused by water mold, and Yu Yue shared a simple solution in the kitchen.

The fish in the fish tank have white flocculents, most of which are due to water mold, and mild water mold only needs to be warmed and coarse salt for a few days. If the symptoms of water mold are severe, penicillin is used in combination**. In addition, if the fish can recover completely, you can use potassium permanganate or malachite green solution for medicinal baths.

The white flocculent matter on the fish in the fish tank may be caused by water mold, most likely due to the deterioration of water quality, or the water temperature is too low and the water temperature difference is large. In this regard, mild water mildew only needs to be isolated and put salt for a few days to recuperate, and the disease symptoms can be improved.

Secondly, pay attention to raising the temperature to about 28 during the resting period and change the water regularly. However, if the disease is severe, an appropriate amount of penicillin can be added to the fish tank, and at the same time, the owner needs to clean and disinfect the fish tank, including all equipment and filter media.

Of course, if penicillin and coarse salt cannot cure the fish, you can use an appropriate amount of potassium permanganate or malachite green, and soak the sick fish in the medicated bath for half an hour every day, which can generally be effective in four to five days.

That's the mucus that the fish itself carries. Mucus plays a very important role in protecting the fish themselves. When the fish is alive, there is a mucus-secreting goblet cell on the fish, which is constantly secreting mucus.

These mucus covered with the whole body of the fish can reduce the friction of the fish in the water, make the fish swim more conveniently, and at the same time protect the cry from parasites, molds, bacteria and other small organisms erosion, and can make the fish have a normal ability to penetrate, prevent external substances from entering the body casually, affecting the normal life of the fish. In addition, the mucus has the power to condense and sink the oak mud floating in the water, making the water in the living environment clear, and it is somewhat useful for prolonging the life of fish that inhabit the often turbid water. For fish that inhabit clear water, when turbidity is caused by floods or heavy rains, mucus has the same effect, so that the fish can breathe smoothly and maintain life.

After the fish dies, due to the presence of a layer of mucus, it can delay the decomposition of bacteria on the surface of the fish, so that the fish will not deteriorate too quickly. However, after a certain period of time, the bacteria deplete the attached mucus segments such as wild nitrogen, so that the fish begins to decompose, and the fish meat deteriorates.
