Well, flaring doesn't mean much of anything--it could just be an aggressive female. I'm sure some of the others on the boards could give you a better idea if you could maybe upload some pictures? My first betta ever was a girl who turned out to be a PK male, so I can understand the confusion. All I can say is that males chase females in a very different way than females chase other females... Plus, when they flare, males' "ruffs" will be much larger than females'.
Either way, I love the name. And I am a Lady Gaga fan, too.
