Flaring all day doesn't seem to be a problem. My divider is see through, and not covered by plants. My males spend a couple minutes a day flaring. Bettas are not really solitary fish. In the wild they come in to contact with other bettas multiple times a week. Keeping them in solitary all the time can lead to stress and other things.
I only have 1 betta left, but he's a cool blue marble!
