The St. Lucie County Aquarium, featuring the Smithsonian Marine Ecosystems Exhibit, opened in November of 2000, after the Center's main 3,000-gallon coral reef exhibit was being retired from the Smithsonian Institution's National Museum of Natural History in Washington, D.C. Smithsonian scientists were the first to put a living model of an Atlantic coral reef ecosystem on display for the public.
