Hoover Building. When it closed, it was the longest continuously operating aquarium in the United States. Approximately 1,700 fish and other specimens from its collection were moved to the National Aquarium in Baltimore. Officials of the aquarium considered ways of re-opening it at another location in Washington, D.C., but they eventually abandoned such plans. References External links Aquaria in Washington, D.C.
