About a month ago I purchased 3 female betta together and started them off in a quarantine tank, then added them to a 10 gallon that had been cycled and properly ornamented. Temperature is great, and its also filtered (but not too much where it'd cause any problems).
I noticed that this particular fish tended to be rather bossy and mean to the other fish. Within the last week, however, she's the one who was being bullied (although it never ended bad considering its a large tank). Up until the last few days, however, she's seemed in good health.
Her colors are still bright and beautiful, but she has the horizontal lines (which I know means stress) and she's constantly flaring. All of the other fish look marvelous and in great shape. I decided to quarantine her (yesterday) and even alone she's flaring.
You're supposed to have a minimun of 4 female bettas in a sorority, some even say six! Females tend to be stressed out slightly in a sorority, but the more the merrier! I was told once that odd numbers are best, so there can be an alpha female. If I were you I'd add some more females (But remove the current females and rearange the decor first!) So that there was 5-7 females! The more females, the more the aggression is spread out. If your fish is stressed from the other fish attacking her, then there's the answer to your problem.

I forgot to mention I bought a fourth a bit ago... she was quarantined then added to the tank. She's doing awesome. The forementioned betta just seems to be getting worse.
Not testing your intelligence here, but are you sure it's a female? Because I think we had a forum member make a post about how one of his/her "females" was actually a male.
If not, I'd still take her out anyway and start treating her if she's hurt =( poor girl. Sounds like if she's still a she, then she's probably not the sorority type.
I'm pretty positive she's a girl... I've had her for about a month now and her fins haven't really grown at all. I've been watching her today and even alone she's flaring. She looks REALLY sad, and doesn't really have the energy to swim around even though she's in a large tank all by herself. I love my Jasmine... :( I want to fix her!
Oh, and another quick note... I noticed she doesn't really spread her tail like the others do. She keeps it kind of, um, I guess you'd call it contracted? I mean here and there she does, but mostly they're small and she continuously flares.
Actually it doesn't have to have long fins to be a male. There's a type of finnage called "plakat". For example, like my avatar picture of my fish, Stamps. But if you're positive it's a girl, then I won't test you
If her fins are clamped, she might be really stressed out or sick. Make sure there's enough hidey-holes in your tank so she can seek shelter when she's had enough bullying if you decide to keep her in the sorority. But if she's weak, I would put her in a quarantine / hospital tank until she got better and regained her strength, then possibly try to reintroduce her later.
Himmm, idk how to treat this, maybe try putting her in with a male, (snd buy a male if ya dont have one) she might get happier and mean flare can turn into happy flares. (maybe im just saying, maybe.)
