I had freshwater tanks for years but I am ready for a reef! I have a great book and spent a lot of time learning about set-ups, requirements, procedures and equipment options and I think I have a good understanding. Perhaps somewhat atypically, I am most confused on livestock. I know I would like colorful fishes, corals and anemones but not sure how to select them. I guess main concern is to make sure the initial equipment purchases are versatile enough that I will be able to have livestock options.

Can someone point to a good resource, maybe with pictures of these critters and suggested "pairings"? Thx!

Oh P.S. Is it a good idea to buy livestock online? Any vendors come recommended?
