Second, how to treat the fish with bloodshot 1, change the water: bloodshot indicates that the water quality is not very good, so change the water for the fish at the first time.

Changing water at this time is not the same as in peacetime, and it needs to be changed more frequently, usually once every other day, about a quarter at a time, so as to improve the water quality as soon as possible and let the fish recover slowly.

2. Heating up: After changing the water, the next step is to heat up.

There are advantages and disadvantages to warming up. The advantage is that it can promote the metabolism of fish, make it discharge harmful substances as soon as possible, and at the same time improve the vitality of fish.

The disadvantage is that it will increase the reproduction speed of bacteria, so it is necessary to add salt to the water.

3. Salt: The role of salt is to increase the osmotic pressure of water, thus reducing the entry of water and also preventing the invasion of bacteria. It should be noted that the concentration of salt should not be too high, otherwise it will affect the health of fish and even lead to its death, usually kept below five thousandths.
