Welcome to the club and the hobby. You will find out there are 1,000s of ways to do something and at least one person will tell you that your doing it wrong. What it comes down to is your fish and corals are happy and healthy.
As many mentioned above take your time and do your research. The best is to first try and decided with path you want to go. Do you want to do fish only or do you want to get into corals? Fish only are simpler systems but corals are nice. If you are doing corals then you need to figure out if you want to do softies, LPS, SPS, or mix. Once you have a game plan then start researching who can go together. Like if you do corals then you can't get fish that nip at corals.
As you do your research don't be scare to ask questions. I have found the folks on this site are open and helpful. I seen many sites where people belittled a newbie for dumb questions. Don't let people like that get you down in this hobby.
