White spot disease is a parasitic disease. Generally speaking, the size of the parasite is very small. The freshwater white spot insect is a small melon insect. This parasitic disease has a relatively fast reproduction and is difficult to treat at the same time. The main reason is that it is very difficult for us to find that it was parasitized when it was first parasitized, so the consequences are poor.
Usually an inexperienced breeder finds that his goldfish body has risen a lot of white spots, which is hard to rescue at this time. This kind of small melon insect, which can be seen under the microscope, has already reached a large number at this time, which can be seen by the naked eye. At the same time, the damage of the parasitic insect to the fish and the damage of the skin barrier are also caused, so it is easier to infect bacteria And so on, leading to other complications, which is a vicious circle process.
Generally, goldfish die of bacterial infection or other diseases after the white spot disease. When you find that the goldfish in your tank has the white spot disease, the first thing you need to do is to isolate the goldfish in time. Next, you need to pay attention to observe whether there are white spots on other fish raised together. Of course, it's hard to see directly with the naked eye, and it can be seen that a large number of goldfish are also terminally ill
What about the white spots on goldfish?
White spot disease, also known as small melon insect disease, is caused by protozoa small melon insect invading the skin or gill of fish. In the early stage of the disease, the pectoral fin, dorsal fin, caudal fin and the skin on the body surface are scattered in white spots. Although the sick fish forage as usual, they often gather on the corners of the fish tank and rub with each other. Sometimes I will rub hard objects with my body, hoping to remove pathogens from my body. After a few days, the white spots are all over the body. The sick fish do not like to move and often float on the water. The disease usually occurs in spring, autumn and rainy seasons.
Powdering disease, also known as white scale disease and oodinoflagellasis, is a kind of fish disease caused by the parasitism of oodinoflagellate. In the early stage of diseased fish, it was crowded in the pool, and the mucus on the body surface increased. There were white spots on the dorsal fin, caudal fin and back successively. Then the white spots gradually spread to the tail handle, both sides of the body and the head. Finally, the joints overlapped and the whole body was like a layer of powder.
The difference between powdery and leukoplakia: the surface of powdery is powdery 'leukoplakia', with the feature of caudal congestion. The body surface of leukoplakia is punctate, and the caudal fin is not congested.
White spot disease or powdery mildew or both can be treated as follows:
The first step: Red potion + bicarbonate + slowly heat up to 30 ℃. The dosage of red medicine is 6ml per 100 liters of water and 0.5-0.8g per liter of bicarbonate. Do not add salt to this formula. Red medicine cannot be compatible with salt.
Step 2: do not turn on the filter and fish tank lamp temporarily after the application of the medicine, but do not turn on the oxygen to avoid the lack of oxygen in the fish tank. Turn on the filter and lamp 2 hours later to avoid the rapid failure of the red medicine.
Step 3: change 1 / 4 of the water the next day, supplement 1 / 3 of the first dose, and cure it for 3-4 days in a row. Stop the medicine after the cure, but the heating rod is still in use. Cool down and evacuate slowly after 3-4 days.
