Q recently introduced me to Kuragehime,
or Princess Jellyfish. I don't watch a lot of anime, but I absolutely adored this one.
It's about a nerdy girl, Tsukimi, that really digs jellyfish and wants to be an illustrator. She and her eclectic housemates lead a happy, simple existence until (dun dun dun) a sylish wealthy individual crosses their paths and decides to be their friend against their wills. There's also a jellyfish named Clara along the way to explain things.
