responsibility? Fish tail has white dot to explain to get white dot disease. This is a common disease, and the pathogen is a parasite called Ichthyophthirius. It usually parasitizes in the tail and other parts of the fish, and white spots will appear in the affected area, and it will spread further. If you want to treat it, you need to raise the temperature properly, because Ichthyophthirius is afraid of high temperature, it will stop growing when the temperature exceeds 25 C, and it will die when it reaches 28 C, and the disease will recover.
1, change water: found fish white spot disease, first of all, immediately change water, usually every other day to change once, the main purpose of changing water is to improve water quality, but also to reduce the number of small melon insects in the water, and the new water has a certain stimulating effect on it, but also can limit its growth and reproduction.
2. Heat up: The best way to treat white spot disease is to heat up, because Ichthyophthirius is more afraid of high temperature. It should be noted that the temperature can not rise too high at one time, the sudden change of temperature is also very harmful to fish, usually up to 2 degrees Celsius a day, continuous warming until the water temperature is maintained at about 28 degrees Celsius.
3. Add salt: In addition to changing the water to raise the temperature, you can also add salt to the water properly. Salt can change the osmotic pressure, which is helpful to prevent bacterial invasion and other diseases of fish. At the same time, because fish need to drain water, changing the osmotic pressure can reduce the excretion burden of the kidney.
