      Fish are ectothermic also known as “cold-blooded” which mean their body temperature adapt to the water temperature (not like us, our body is suppose to stay around 37 degrees, more means you have fever). So I don’t think fish can die from cold and froze. However is the water is frozen around the fish they’ll die after a time (they need oxygen in the water and to eat).
      Also depending on the fish specie they like certain range of temperature, for example rainbow trout prefers cold water (10-14 degrees), and they faint at warmer temperature (24 degrees) whereas Tilapia like warm waters.
