If the goldfish has white skin, first the owner should fish it out, then use cotton to absorb the water from the goldfish's body, and wipe the goldfish's body with hydrogen peroxide. During this process, be careful not to let the hydrogen peroxide flow into the gills, and then add water to the fish tank. Change the water, raise the water temperature to about 28 degrees, and then pour some salt into the tank to disinfect it.

Tip:

White skin on goldfish may be caused by saprolegnia or leukoderma. It is usually caused by low water temperature or poor water quality. Owners should pay attention to changing the water frequently, changing the water every 1-2 days. Do not pour tap water directly into the house. Leave the tap water for 1-2 days until the chlorine inside has evaporated before changing the water.
