I agree with Hiro, I have Cherries in 5 or 6 unheated tanks that get down into the low 60's at night. They're not as prolific as they are in my heated tanks, but they still reproduce. Outside of the cherries, maybe some gammerus (http://youtube.com/watch?v=55Wo9PIkdgY&feature=related), fairy shrimp (http://youtube.com/watch?v=Ye3Dpheijjg), or triops (http://youtube.com/watch?v=jsqiYxGEdnI)? Pretty much any fish would pick off the gammerus and fairies, and triops might be able to pick off fish. As far as fish go, I think guppies, bettas, and white clouds would all survive a one gallon unheated tank if it had plenty of moss?
