Actually, flaring is a natural response for the betta, and as long as they're not constantly flaring, it's not going to cause them harm. You don't want to leave a mirror in the tank for long periods though, as it can stress them out when they see that the intruder is not leaving...
My guys tend to have little flaring contests in the morning, but settle down after a minute or so when they're all sure they won...amazing how many winners I have in my house...heh
