I think I know what you mean with the beard thing.. Is that the dark-colored portion under the gill flaps? That you see kind of poking out whenever the betta flares? At first, I was like "What is that on that betta??? O.O!". xD! I thought something was wrong with the betta. Lol. Now, I'm wondering what it looks like when a female flares.. I have considered a sorority, actually. =] Then, the females would outnumber the male. xD And, for some reason, I'm paranoid about mixing up my fish.. Like.. What if I get five females, and two have similar color patterns, and I'm not able to tell them apart, so I just call them one another's names? o.o My betta does that, too! :D He jumps up at my finger whenever he thinks I'm going to feed him. That must be true; Turbo doesn't jump very high, but it's still pretty cute. xD I was showing my sister today. He's eaten from my finger before. It feels so cute. Lol.
I've heard a lot about females having more personality and being more active than males. Maybe, the stereotypical emotional female thing is true with fish, too. Lol.
