I've read in numerous places that it's best to go slow when adding fish, CUC, and corals to a new tank, as to not overload the tank and cause a crash. So, add some snails, then a fish or two, couple of corals, then some more snails/crabs, more fish, etc....
For those just starting up, and have yet to add any fish, I recommend you add the "nicer" fish first. I added a 5 in fairy wrase yesterday and a bicolor psuedochromis about a month ago. My tank already had an Ocellaris clown, yellow tang, bi-color dwarf angel, and orange spotted goby.
My psuedochromis has to hang out in a small crevice to avoid the angel, and my little clown is picking on the wrasse, despite being 1/3 the size.
If I were to do it again, I would have added the goby and wrasse first. Then the tang. Then the clown and bi-color.
Lesson learned: Do you homework on the fish you want. Plan to add the most aggressive last. I think it would have made a difference with the harmony in my tank.
