Saprolegnia is a kind of fungus, which usually invades fish when the temperature is low. If you want to treat it, first of all, you should isolate the sick fish so as not to infect other healthy fish, and then put in some antibacterial drugs, or use povidone iodine, potassium permanganate and other drugs to soak and wash for treatment, each time you need to wash for about 20-30 minutes, you need to pay attention to the concentration of drugs, so as not to form drug damage.
1. Main heat preservation: saprolegniasis often occurs at low temperature. Because the temperature is relatively low at this time, the resistance of fish is very poor, so it is easy to be attacked by bacteria. In order to prevent illness, the first thing to do is to keep the temperature above 15 C, preferably around 20 C, but not too much temperature fluctuation.
2. Avoid injury: Saprolegniasis is caused by Saprolegnia, a fungus that invades from the wound of a fish, forming hyphae and turning into white flocculent material. If the fish is healthy, the possibility of bacterial damage will also be reduced, so in peacetime must avoid injury, do not put too sharp stones in the fish tank.
3. Water source safety: As long as the water source is safe, the possibility of fish suffering from saprolegniasis is also very low. General water more than tap water, this water after disinfection treatment, there will be no harmful bacteria, but there will be residual chlorine, need to air it.
