Glenn,
First, welcome to RF.
Second, planning.
You should have a list of all the fish you want in your tank FIRST. From there, introduce the most passive ones first and aggressive ones last.
For example, in my 375 gallon, I knew exactly the fish I wanted (mostly large angels and tangs). I started by adding small fish first, wait 2-3 weeks, then added more fish, wait another 3 weeks, etc. To make a long story short, the last fish I added was an emperor angel as it was the most aggressive. It took me almost 2 yrs to stock the tank.
I am not saying it will take you this long, but I am old fashion and like to wait a good portion of time before I added additional fish.
any questions,let me know
Kirk
