That's too small for a betta. They appreciate space. It's very difficult to heat anything under 2.5g. I would get him something like a 2.5g, and then we can advise you on the best heater :) In that half gallon tank, you need to do water changes 100% every other day because of the ammonia that builds up in that small of a tank, which will harm him causing his fins to rot.
