We've never been a fish enthusiast, but this swanky Fish Hotel makes us want to become one. The hotel can stand by itself, or it can be stacked with others to create a "condo effect."

It can also be used as a terrarium, along with countless other clever things, we venture to guess.

It's available at SFMOMA's gift shop — our go-to, downtown, gift-shopping spot. They've even compiled a Holiday Guide featuring their most popular items.

Also, be sure to check out the Bird Cafe Feeder, the perfect gift for your friends with prime real estate (ie, their own backyard).
