[Things I should know before working at fish/reptile pet store]

I recently put in an application for a local pet store. I love animals and have had dogs,cats,birds, and snakes. So I am looking for information about fish. So what temperature should their water be? How often should the water be changed? What should I do if fish get sick? What are the best fish for beginners? What should happen if all the fish in the tank die?
