...we had enough we have 4 tangs on order because at our LFS he has tons of coral and tons of fish...
Judging from the good advice your LFS has given you so-far, I'd like to believe that they have a few more years, if not decades worth of experience in the hobby than someone just starting does. Couple that with the fact that employees are in the store and interacting with the tank way more often than a typical hobbiest with a job can be interacting with his/her own tank, and they can keep tons of fish and tons of coral. Remember, these guys know what they're doing and can be there all the time, not something most of us can do
Example: one of the display tanks at my LFS (120g) is jammed full with 22 fairy wrasses, a couple tangs, anthias, clowns, and cardinal fish. It is also home to 20-30 different species of coral. The tank is managed by one of the store owners who'se been in the hobby 15 years now... When I asked him how hard it was to get that much livestock living in the same space he replied: "15 years of hard-earned experience"
So with that in mind, take your time, sit back, and enjoy your tank. As you've allready noticed, there is a never-ending learning curve in this hobby, so research research research
