Welcome! As for as nothing dying, congrats! Hopefully you don't have much else other than damsels, because if your tank is newly setup, once that cycle kicks in you're going to stand a good chance of losing fish.
I'd RUN to the bookstore and get "Saltwater Fish for Dummies". Dont' worry about the title, its a GREAT source of info for newbies and vets alike. Unless, of course, you're just too cool to buy something with that name.......
And by the way.....you need to worry about NitrItes more than NitrAtes. The book will explain how and why.
