Fish, because they are numerous, are used as symbols of fertility and prosperity and because their eyes are always open, and they see everything, they stand for knowledge. On Rosh Hashanah, the head of the fish is placed before the head of the family. And he or she says, on behalf of all those at the table: "May it be your will that we be like the head (leaders) and not like the tail (followers)."
