I have my Betta in a small 2g tank. I live in Phoenix so heat is not usually something we consider adding. However, our apartment has been known to go down to about 65 in the winter. How cold can a Betta stay healthy in?

And do they make a heater that small?
 
Wow! 80? I feel so bad now. I have seen it drop to about 72-74 overnight and is usually around 76-78 during the day.

I said close to 80. 76-78 would be fine but not sure if any lower would be ok...
 
Anything 70-80F is good. Preferably in the mid-70's range, and try to keep it as constant as possible. 82F is about the high-end of the comfortable range, and anything over that is starting to get too hot.
I know several people that have had good luck with the above-mentioned heaters for small (<5g) tanks.
 
Be fore warned, the heater has no contol, if its plugged in it is heating. And it doesn't turn off unless unplugged.

Well that really sucks! Not sure I really want to risk that. The winters here are much like summer elsewhere, we leave the windows open all the time. It'll be 70s, 80s during the day and then go down at night. If it goes down to 60 or so in the house we close things up, and we rarely turn on any heat.

Ok so the question is still this... how low can it go? Is 70 the absolute bottom before my fish will just go belly up? I suppose I could get this thing and only use it over night, but it's not going to be easy to monitor while I'm sleeping. Any other suggestions?
 
I have a Hydor Theo 25 watt heater in my 2.5-gal fry tank, and it keeps it nice and stable. This heater has a dial to adjust the temperature, and a thermostat, so it's only on when the tank needs heating. Much better, and safer, in my opinion, than a heater that isn't adjustable and is always on.

Before I got the 2.5-gal tank, I had this same heater in a 1-gal tank, and it worked great in that one as well.

Anyway, I highly recommend the Hydor Theo 25. :dance2:

that's not entirely true.. most heaters nowadays are the thermostat variety, and they come on when the water temp drops below a certain temperature.
I recommend all aquariums have heaters, if for no other reason than to keep the temperature from fluctuating too quickly. even on my goldfish tank i have a heater set to 65, so that it doesn't drop too quickly in the middle of the night.
 
yes, most do. But the one that was linked, does not have a way to adjust nor does it automatical turn off.
