How cold can I keep a reef?

I have a 1 gal nano and don’t have heater for it, would it be necessary, the most temperature sensitive I would get is corals.
Right now it’s around 73 would that be ok for a reef tank?
Thanks

Unless you're keeping a Deepwater reef than no, the tempature needs to be around 78 degrees Fahrenheit, otherwise it could harm fish, coral and inverts

Ok thanks, I’ll get a small heater soon.

My mixed reef runs around 76° F. Old habits I guess, from the days of worrying about metal halides and VHO bulbs heating up my reef tanks. 75-80F would be best
