In winter, we need to pay attention to some problems in order to ensure their safety. First of all, the problem of water temperature, if the fish tank is outdoors, you need to use a heating rod to increase the temperature, for indoor fish tanks generally do not need to use. Another thing to pay attention to is the feeding problem, because the water temperature may be relatively low, so their activity or appetite may be reduced. Then, you have to adjust the amount and frequency of feeding according to the water temperature, if the water temperature is low, you can feed once every other day, and the food can not be put too much.
Then there is the problem of light. In winter, the daily light time can be more, about four hours. Finally, the problem of water exchange, winter also needs water exchange, but not too frequent, can be adjusted to one or two weeks according to the specific situation, and the amount of water exchange is not too much, otherwise the water temperature will change greatly, Lanshou will appear inadaptable situation.
In the winter breeding Ranchu, a need to pay special attention to the water temperature. Ranchu is a cold water fish, its adaptability to water temperature is relatively good. Generally speaking, the water temperature is between 15 and 28 degrees, and Ranchu can grow normally. If it is around 10 degrees, it will not affect the survival of Ranchu, but their development may be slightly weaker. If the water temperature is low again, you have to pay attention to the appropriate use of heating rods and other tools to increase the temperature, to avoid accidents. Generally speaking, it is not necessary to heat the fish tank which has been placed indoors. If it is placed outdoors, the heating rod can be used appropriately to increase the temperature.
