Ya totally agree. It really pays to sit down, and figure out your stocking plan. You got one fish to start with, look at some others you like, and think of the corals you want to keep. Then build a plan around that.
My 3 favorite community fish are pearly jawfish, engineer goby, and just about any anthias, and I want to keep clams, plus LPS corals, so stocking plan for my big tank is built around a community that supports or co-exists with those.
