I don't see what the proble...*Rubs Eyes* Oh my... I'm totally baffled and I thought I was pretty good now on diseases...

(All I did was research about Drax's eye and strange coloring for awhile so I think I'm decent now with trouble shooting)

... it's obviously a cyst of some sort (EXPERTS EXPERTS WE NEED EXPERTS! *Flails*)

Oh... I found that site which talks all about cysts and tumors on betta's.

Long as she's healthy otherwise then it probably isn't bothering her, adding AQ or Epsom salt may help, and sometimes the lumps go away.... and sometimes not.

That looks exactly like Whiskey's tumor did. He lived with it just fine for about 8 months after it appeared. But, sadly, it eventually burst and I had to euthanize him. It will help if you keep her water very clean and make sure she's warm enough. 78 is pretty good as long as it's constant and doesn't fluctuate a lot. I initially tried antibiotics and aquarium salt but they had no effect on the growth.
