? Generally, guppies do not need salt, because they are freshwater fish. If they put salt for a long time, they will feel uncomfortable. And if you put too much salt in them, they will fade, and in serious cases, they will be dehydrated or even die. Although guppies do not need salt in their usual feeding process, they also need salt when they are sick. When treating diseases
of guppies, the amount of salt should not be too much, and the concentration should be 2-3%. You can also choose to use saline bath, but after the bath, you need to rinse it before you can put it into the original jar. When putting salt, we should choose special salt for ornamental fish or sea salt, not edible salt, because edible salt contains iodine, which will cause harm to the body of guppy.
? Guppies like water at 22-24 degrees Celsius. Although they are tropical fish, the lowest temperature they can tolerate is 16 degrees Celsius. So in general, there is no need for heating. However, when the temperature is too low in winter, it is recommended to open the heating rod for constant temperature. Moreover, in early spring and late autumn, the temperature changes greatly. If the guppies are kept outdoors, they also need to turn on the heating rod to keep the temperature constant, because the temperature difference between morning and evening in early spring and late autumn is large, which can easily cause them to have stress reactions.
