Hi Patti: I am researching my first saltwater tank, so I am not too far behind you...
Take a look at the articles section of this website. There is a good article about cycling your tank without fish. That is what I plan to do, rather than subject a damsel to that just because they are hardy. Your LFS
will lose the sale of the damsels, but oh well... you'll be able to get the fish you really want when your tank is ready. I've heard the damsels are aggressive too... I have aggressive freshwater fish. I plan to get SW
fish that play well with others!
