Will the snakehead raised at home freeze to death in winter?

No, in winter, the river freezes, the fish are underwater, the temperature of the river is below zero degrees Celsius, and the underwater temperature will not be below zero degrees Celsius, so it is still suitable for fish to survive. On the contrary, the river was covered with a thick layer of ice, which undoubtedly covered the river with a thick quilt. No matter how cold it is outside, the river under the ice can keep a constant temperature and the fish can move forward as usual.
