Justin Muir, founder of City Aquarium in Brooklyn, N.Y., designs custom fish tanks. But think big: these aquariums run his clients (primarily celebrities, professional athletes and Wall Street moguls) anywhere between $50,000 and $400,000. We went on a fish shopping expedition with Muir and visited his warehouse, where he cultivates giant clams and coral, and medicates his fish before they are transplanted to his client's aquariums.
