    Bettas are pointless fish. They are for 6 year olds to look at and say 'Mommy, pretty fissy'. Little more.

    You need to get a bigger tank. Bettas need 5 gallons minimum. 

    What wattage heater you need depends on the ambient temperature. A 25 or 50 watt heater should work for a 5 gallon.

    The heater should be at least 15 watts.
