Stock for 125 gallon reef?

So in debating to make my 125 gallon a reef, I was wondering what the stock level could be, as in how many fish, ranging from 1 to 3 inches, could comfortably go in. I was also wanting 1 or 2 show fish, ranging from 5-6 inches. So with that in place, how many could go in comfortably without it being overstocked?
