Sorry, are you asking what we all think is the best size for a betta? Or, are you just telling us that you are looking into it? Just checking. Either way, congrats on setting up a nice betta home!
A 5 gallon for a betta would be perfect. With a 10 gallon you could have a betta and some friends (depending on the personally of the betta). I heater to keep the temp at 80 and a filter with not too much water flow so it doesn't knock the betta about. Substrate of your choice, somewhere to hide and some real or fake plants. Make sure there is nothing in the tank that he could get his fins/tail caught or torn.
