Potassium permanganate is generally used to disinfect fish. This is a common sterilization and disinfection drug. It should be noted that the concentration of this drug should be controlled within a certain range. If it is too high, it will easily affect the health of fish. If it is too low, it will not be effective. Generally, the highest concentration can not exceed 2/10000, under this concentration, the bath can be 10-15 minutes, if there are adverse reactions, it should be immediately fished out and fully supported. It can also be soaked in drugs with a concentration of 15 to 20 parts per million for about two hours.
Usually, only when you open the tank, you need to disinfect it once. Disinfection is mainly aimed at the old fish tank. As long as the new tank is cleaned, there is no problem. Frequent disinfection is actually harmful to the health of fish, generally only when fish have diseases need to consider disinfection, but if there are corresponding drugs, medication will be better than disinfection.
The choice of medicated bath or the whole jar of medicine mainly depends on whether a fish is sick or all the fish in the jar are sick. If only one fish is sick, take it out of the tank, and then take a medicinal bath, the concentration of the medicinal bath is generally higher, so the time can not be too long, half an hour is enough. Medicated bath once a day, after a few times in a row, basically healed. If all the fish in the tank have symptoms of infection, they need to be drugged in the tank, but for some serious cases, it is better to take a separate bath after isolation.
