Umbra Fish Hotel
Let's be honest: your fish probably doesn't care what his surroundings look like, just so long as his water is clean and he's well fed. But you have to look at his bowl/tank every day, so you might as well make it stylish. The Umbra Fish Hotel ($35) certainly qualifies, featuring the clean, boxy lines of a modern home, a glass bowl, an ABS pastic facade, and a stackable design that lets you build an entire condo full of fishy friends.
