How cold is your average ambient temp? I think there's a lot of fish that are hardy enough to handle "American average household" room temperature. I've had danios (zebra and giant), adult female bettas, and white cloud minnows in unheated tanks in my apartment. White cloud minnows, specifically, can handle temps down to 55 deg f, according to various web sources.

Almost all of my experience is with fish at the 78-82 temp range. Would anyone like to suggest their favorite fish who can handle an unheated tank? I?d like to get some short term pals to live with my Koi until the summer when they will need the whole tank.
