Answer 1

  Medicating when a fish, or any animal is not actually sick is a very bad idea.  This is how drug resistant strains are created, when your fish does get sick with one of these the med you have been using as a preventative will not work, and a med that will work, if any, will either be expensive, hard to get, or just plain not created yet.
