Fish can point mosquito incense. Although the smoke of mosquito incense dissolves in water, its main component is pyrethrin, which is harmful to arthropods, such as shrimp and crab, but has little effect on fish. However, the concentration of mosquito incense should not be particularly large, and it is better to maintain a certain degree of ventilation, if the top of the fish tank is covered, it will be better.
1, water temperature can not be high: summer fish should first pay attention to water temperature. If the water temperature is too high, it will easily affect the health of the fish. And high temperature will accelerate the reproduction of some bacteria, adequate light may also make water eutrophication, leading to the phenomenon of algae explosion in fish tanks, so we must pay attention to cooling.
2. The temperature difference should not be large: In summer, the temperature is high in the daytime, and the temperature will drop at night. The large temperature difference is unfavorable to the growth of the fish, and may even stimulate the fish body, affect its appetite, and may even cause its death. Therefore, in addition to cooling during the day, we should also pay attention to the night, do not let the water temperature drop too low.
3. Feeding should be quantitative: When the temperature rises, the activity of the fish will be more vigorous, and the appetite will also increase at this time. Compared with normal times, when feeding the same amount of feed, the fish will still have the situation of grabbing food, but at this time, do not continue to feed, otherwise feeding too much will cause the fish to die, and the residual bait will also pollute the water quality.
4. Change the water in time: Compared with other times, the temperature in summer is higher, and the speed of water body decay is also increasing, so it is necessary to change the water in time. The time for changing water is usually in the afternoon or evening, and about one quarter or one third of the water can be changed each time.
