Got a new betta after a year!

I just got this female betta after over a year of avoiding bettas due to my last one dying of completely unknown causes. Totally demotivated me for a long time and I'm really going to try and do my best for this girl here. I have confidence since I got her from a very reputable LFS that kept her in a big and healthy sorority tank.
She is absolutely huge, but super nice to all the other fish and shrimp in my 20 long, and absolutely gorgeous.
Name ideas? I'm completely stumped
