I think I'd endow a nicer reef tank for the NE Aquarium, something larger and more like the 200,000 gallon reef tank at the Steinhart Aquarium in SF. I'd still like to have a nice 200-300 gallon tank at home, but that much money could fund a real exhibit large enough to support more diverse coral/fish life for the public. Most aquarium exhibits are underfunded and it would be great to see a grand scale project with proper staffing, equipment, and budget.
