Labyrinth Aquarium
Give your fishy friends something to do other than just glub around with the Labyrinth Aquarium ($5,500-$6,500). Made from Lucite, this six-globe aquarium is designed for tropical fish, and includes silk plants, three lights, filters, air pumps, and cleaning equipment, as well as an optional dedicated table in cherry, black, or carbon fiber. Just think of it as a Biorb on steroids.
