2.5 gallons per ADF just like 2.5 gallons is minimum for 1 betta. 2 ADF's is better than 1 though just because they are social creatures and like friends.
If you are dead set on getting 2 and cant/wont upgrade, you're going to want really good filtration and keep up on your water changes as your tank will be over stocked.
