If it will be a full reef system
here are a couple of fish to research that are good:
firefish
yellow headed jawfish (or pearly)
clownfish
lined wrasses(reef safe)
blennies(certain kinds)
gobies(certain kinds)
that is all i could think of that will for sure be good for almost any saltwater tank.(underline almost) be more specific with what you are going to do with your tank(inverts,corals,etc.) and ill give more detailed suggestions.
