If the fish is sick, it is a troublesome thing. After we deal with the fish’s illness, preventing the fish from getting sick is a major event. If the fish get sick, don’t worry. Take active treatment and medication, it will be good. Today, share the methods to prevent illness.

The external reason why fish get sick is the difference of water temperature. First, fish are cold-blooded animals. They are very sensitive to the difference of water temperature. If they are difficult to adapt to the change of water temperature, they are easy to cause disease.

Second, the difference of water quality. The water quality is not suitable for fish. There are too many changes. The reduction or increase of microorganisms in the water will affect the water quality, thus affecting fish.

Third, the change of dissolved oxygen. If the dissolved oxygen is not adjusted properly, it will also cause them to get sick.

When we are at a loss and the fish are sick, we can take them to the flower and bird market and ask those sellers to help us. Or ask directly and go to the pharmacy to buy medicine for the fish.

Some players say that their fish will bleed from their scales. The biggest reason is the water quality. We need to ensure the cleanliness of the fish tank and change the water. Then isolate the sick fish from the healthy fish, and adjust the temperature of the fish tank appropriately for observation.

Spring and winter are the seasons with the highest incidence of fish. The incidence bank is not only high, the disease period is also long, and the curative effect is low. If the treatment is not timely, it is likely to cause the health problems of the fish in the whole fish tank.

You can pay attention to the following defensive measures. First, before putting fish fry, you must clean the bath to avoid fish lice. The water to be put into the fish tank should also be filtered. If it is found that fish lice can be sterilized with 2.5% trichlorfon per cubic gram.

Second, to effectively control the water quality, it is appropriate to discharge the sewage at the bottom and put clean water with the same water temperature. The change of water should not exceed one-third of the total water volume. If it is equipped with oxygen properly, it should be oxygenated. In this way, the living environment of fish is better and their disease resistance can be enhanced.

Third, feed at the right time. The sleeping temperature is generally about 6 degrees, which is more suitable for feeding. It’s better to feed fish, insects or artificial feed. Try to be less than more, so as to ensure that the bait does not stay overnight. Proper feeding can also enhance the physique of fish.

Fourth, the water temperature difference is too large. Generally, if the room temperature is better, it should be about two to ten degrees. If the water temperature rises and falls, it should be gradual, not high and low, and let them adapt slowly, otherwise it will cause colds, heating or imbalance.

Fourth, even if the water body is disinfected, put five grams of salt in every 50 grams of water in your home. If it is to disinfect the fish, this method can also be used. Usually once every half a month, you can also pick up the fish and change the water by the way.

These small methods hope to help everyone and make our fish grow better and healthily.
