Do crucian carp swim back at night? The current temperature is 10 degrees during the day and 1-4 degrees at night. How about night fishing?

The current weather is not suitable for night fishing. The temperature is too low at night, so the crucian carp swims to deeper waters. After the temperature rises during the day, probably after 10 o'clock, the crucian carp slowly moves from Swim to places with grass or piles of rocks in deep water to look for food. By 2 to 3 o'clock in the afternoon, crucian carp can completely look for food in the grass less than 1 meter
