fish indicates that it has Saprolegniasis. This is a common disease, which is usually caused by Saprolegnia invading the wound after the fish is injured, and the mycelium grows from the wound, which looks like a white fog. It should be noted that there are more than ten kinds of pathogens causing this disease, of which Saprolegnia and Achlya are the most common, and generally only when the water temperature is low, it is easy to suffer from, so we must pay attention to heat preservation.
Saprolegniasis 1. Change the water: The first thing to do to treat Saprolegniasis is to change the water. Too many harmful bacteria in the water are the main cause of its illness. Changing the water can improve the water quality as soon as possible, and at the same time reduce the number of bacteria in the water. Usually, water should be changed every other day, so as to achieve the goal of reducing germs.
2. Warming up: After changing the water in the fish tank frequently, it is necessary to raise the water temperature properly. The purpose of warming up is to accelerate the metabolism of the fish, so that it can discharge harmful substances as soon as possible, which is of great help to its recovery. However, warming also has some disadvantages, that is, to promote the reproduction of harmful bacteria, so salt is needed.
3. Salt: Usually, salt is not added to the fish tank to sterilize, because the maximum amount of salt is only five thousandths. This standard can not sterilize, but it can change the osmotic pressure of the water body, reduce the infiltration of water into the fish body, so as to prevent the invasion of bacteria and fungi.
