1. Maintain water quality: hot weather, high water temperature, active magpie flowers, increased appetite, and fast growth; at the same time, there are a lot of feces and dirt discharged, coupled with the proliferation of plankton in the water, the water in the fish tank is very easy to breed bacteria, which endanger the growth of magpie flowers. Especially in summer, the water should be changed frequently, some of the water should be changed once or twice a day, and the water should be completely changed once a week. The best time to change the water is in the morning and evening.

2. To control the water temperature: if the water temperature in the fish tank exceeds 30 degrees Celsius, magpie flowers will easily Hypoxia and scalded tail disease occur, which are a great threat to magpie flowers. At this time, cooling measures should be taken to reduce the temperature to below 30 degrees Celsius in time. In addition, the fish tank should be placed in a ventilated place, which can not only cool the temperature but also ensure sufficient oxygen supply.
