he may not thrive, but he will definately live to old age.
I live in canada too and my betta lived over a year with no heater in a small tank too.......you see what he looked like when i bought him in my avtar.
He was VERY lathargic, tiny, no colour only ever layed around.
I moved him into a 5g heated tank.
This is what he looked like 1 week into his recoup from those living conditions. (and @ his worst he had lost ALLLL his colour)
So yes...they can stay alive....but look what it does to them! :(
After around a month and a half now this is his what he looks like
Seems pretty simple to me.
