I assume that both of your tanks are new. So is mine. I have a book that Ive been reading for a while called "The New Saltwater Aquarium Handbook." This book desribes the white spots as parasites and oxygen concentration. I have the same problem so I went out and bought some cleaner shrimp. They will eat the parasites off the fish. If your tank is like mine there is alot of the white stuff in the water and on the glass. Ive been told also that they can be sea fleas. They dont sound to be harmful. Get a second opinion there may be others that will disagree with me.
