Hah! So says someone who lives in Texas.
I think the only homes in the U.S. kept within that sweltering temperature range are those in the Deep South, or those owned by the elderly.
Although I am not elderly yet, I do live in Florida which has subtropical temps. There are about 2 or 3 cold fronts that reach us each year, and my tank temp dips to 72-74. I didn't lose any fish when this happened, but I know they weren't too thrilled about it.
If I am on the fence about whether or not to get a heater (for use during cold snaps), I imagine a heater is a must in the Pacific Northwest. So for the USA, I have to side with TEAM JACOB. I figured vampires prefer cold temps.:silly:
