livestock for a 6 gallon nano cube?

[ricecakes885]

i'm trying to do some research for when i get a 6 gallon nanocube in the next couple of months. i want to be fully prepared so i don't make any mistakes or waste any money. i understand it's very small and i won't be able to fit much in there but my question is, what else besides live rock, meaning fish coral and inverts, can i put in there, and how many?
thanks so much!
also, how much live rock can i put in there?
