I'm hesitant to answer, because I'm not super experienced. However, from what I have gathered around the site, a heater is a necessity for your main tank. Seeing as Betta are tropical fish, their tank should be anywhere from 78-64 degrees F. I wouldn't think that a heater for your little half gallon during water changes would be necessary; unless you plan on having him stay over night (at least that would be when I'd get one).
I hope that helped. This was only in reply to your other quote. I haven't read the rest of the forum yet, though.
