No they do not fight as adult. These are one of the most non-aggressive community fish. I have galaxy rasboras in one of bristlenose tanks with zero issues. You can definitely keep a few in a 20 gal long.
i bought three fish from her and they arrived today with no issues, perfectly active and healthy, she did a very good job shipping them and they're absolutely awesome!
