This is kinda wrong. A heater is a must in the cold seasons unless you want a cold unhappy fish. Temp is dangerous and you can't depend on luck forever peaches. A filter is a recommended thing and will be helpful during the cleaning period. A half gallon tank is too small and will need more cleaning then that! Peaches, a happy betta would be in a 2.5 gallon or a 5 gallon not a half gallon.
PM me if you want to defend your post.
Back to topic, a good tank would be a 3-5 gallon tank with a nice filter and smooth rocks at the bottom and a few plants to make the tank less boring. A nice background and a good light. Also an adjustable heater is highly recommended. Also have a thermometer to keep tract of heat. You will need water conditioner to make the water safe. Test the water and cycle it and that should be a good tank.
