Will clownfish do well without heating?

Hi,
At home i have a rsm130 reef, and i want to start a nano marine at work with a 13g tank.
Do to saftey issues i cand bring any heating electrical equipment, so my question is will clownfish be ok in the winter in 22 degrees. 21 is the minimum it will get, most of the winter they will be 22 at night 24 at day time. On the sunner i will bring fans and it will be 26 or so.
What do you say?

They are a tropical fish like most we keep in SW. They gotta have the water temp 72-79. I'd not have them in a tank getting any lower, they aren't like a goldfish. 24c is ok, but the 22 is getting out of the low range, should be ok there but, I'd not let it go lower.
