If the water is not changed regularly, they may be infected by bacteria because of water pollution, which increases their risk of illness. The amount of water exchanged

2. What

should we pay attention to when changing water for Manlongyu? In order to avoid their illness due to improper water change, we should pay attention to the following points when changing water:

1. We should not use the tap water that has just come out. Because tap water contains a lot of chlorine, they can cause damage to the gills of fish. Fresh tap water should be dried for several days before use.

2. A small amount of water should be changed. Do not change too much water at one time. Change about one quarter to one third of the water in the fish tank at a time. Changing too much water may cause a sudden change in the water quality environment.

3. Do not change water by force. Use the siphon method to suck out the old water from the bottom of the tank, and then pour the new water slowly into the tank along the wall of the tank.
