What about goldfish when it is hot in summer?

1 The higher the temperature, the higher the water temperature. The higher the water temperature, the faster the fish digest, the more they eat and the more they excrete. In addition, the air pump accelerated the deterioration of water quality.

The size of an aquarium is closely related to the number of fish. If the aquarium is not big, the number of fish should be reduced, and individual fish should not be too big.

3 When changing water, pay strict attention to the temperature difference between new water and old water. The temperature difference cannot exceed plus or minus 2 degrees, leaving 3%+0 old water.

4 Feed regularly and quantitatively, and the food intake is about 10 minute. If there is any surplus, it should be unpacked and taken out in time to avoid corruption and water pollution.

5 Aquarium should not be placed in direct sunlight.

6 When changing water, use a transparent plastic straw to suck out impurities and feces that sink at the bottom of the box.

7 Add a few grains of crude salt to the fresh water (this salt contains no iodine).

My friend, the above is my experience, I hope it will help you.
