The two best are Strictly Fish and Gables Aquarium. The owners are good friends. George owns Gables, its a small store but has really nice corals (305) 662-7300. Stricty is larger, ask for Louis, they have great rock and lots of corals to pick from (305) 227-9414. Tell them I sent you. Both stores have two trucks apiece that do maintainance full time. Last I heard, Gables had over 300 accounts. Another store that is good is Exotic Aquaria, they are a little rude, but they have a large selection of fish.
