The live rock and sand I bought from a local guy who aquacultures it himself locally. He also sells corals and soon gonna sell fish. Check out their website. Atlanticseafarms.net
As far as fish, I made my first purchase from animal jungle. After looking around i wasnt too happy. They have some huge aiptasia anemones, if you want to know what one looks like go there. Also the corals were covered in algae. I purchased my other fish from Care a lot. Im going to check out fish safari. They pretty much specialize in salt water fish.
Also check out hampton roads reef club. Im on there and lots of local people to talk, trade, sell, and buy reef items and livestock
