I've had some fish tanks in my day, but this one puts all those to shame! The Silverfish Aquarium is sure to wash that cabin fever right out of your pet's freshwater fins. This 60-gallon, six habitat tank allows your fishies to roam further than ever . . . and not just swim in small circles. I know what you're thinking: cleanup is probably as complicated as it is messy, but with superior water filters, the maker promises that cleaning this fish palace shouldn't take longer than any other standard 60-gallon tank. At $3400, I can't see myself getting one anytime soon, but surely this aquarium has a place in someone's futuristic (possibly geeked-out) home.
