Also, do yourself a favour and get some of these dwarf hermit crabs, they are awesome at cleaning your rocks, I bought 10 and want to put about 30-40 in my tank, they are awesome workers.
Although right is a matter of opinion, the one which makes most sense to me is to not stock the tank until you have added all your liverock, corals and pumps.I want to stock the tank right from the outset and I am looking at 5/6 compatable fish that are reef safe and will be in for the long haul.
