When I first joined, I had my girls in bowls, without a heater. I got them a heater and thermometer at the same time. As I suspected, my room was warm enough without a heater to keep the bettas warm.
Three of my tanks have heaters, but one of them doesn't and the little guy who's in it is perfectly fine. He's even MORE active than some of my bettas that DO have heaters.
I agree that some fish don't NEED large tanks. Some people have limited income, and can't afford all the "extras". My betta, Spazz, is quite content with living in a 1.7 gallon tank. He's happy, he builds bubble nests, greets me everyday, flares like crazy. If the betta is happy and healthy, I think its fine. I think size IS important, but I also think maintaining the tank, cleaning, feeding etc, is MORE important.
Life with Lupus is still a life worth living.
