They don't have to, but for smaller fish, it ensures greater protection. Schools of fish are a part of what is called "clumped distribution" in which a population is found in high densities. Usually this is because of certain abiotic factors that are concentrated, but in the case of fish, clumped distribution decreases the chance that an individual will become prey.
