really you want to start with fish only, but plan on making it a reef, unless you decide during the build you like the just fish look
what I mean is go slow, get your LR, clean up crew, and start with a couple small fish (AFTER your cycle of course) then as you get your tank established (at least 6 months) then you can slowly add corals and anemone's
the biggest thing to know in either case is slow slow slow
take your time and have fun but if you want to end up with a reef then you want to buy reef equipment as you are building, i.e lights, skimmer and so forth
