For those who have everything: Silverfish Aquarium

last updated 10 January 2015

This “Bond-villain lair” makes a “spectacular” home for fish. “Handmade to order” on the Côte d’Azur, the Silverfish Aquarium stands nearly 3 feet tall and makes life for your marine or freshwater pets a constant adventure. The aquarium comes with lighting, a heater, and “luxurious” silk plant foliage in each compartment—“enough for fish to hold secret meetings together in total privacy.” All you need to add is gravel and residents.
