She looks like my Violet. Pretty girl. Keep her water clean & warm & she should do great. How big is the tank & how long has it been running? If its newly set up you'll want to test the water daily to keep an eye on the ammonia, nitrites & nitrates & do water changes to keep it safe for her. Also it looks like the filter outflow is pretty strong so keep an eye on her & baffle it if she doesn't seem to settle in the next couple of days. Too strong of a flow can keep her stressed & you don't want that. My Violet loses her colors when stressed, which looks like your girl. When she settles she'll probably be a beautiful dark color. Feed her pellets & once or twice a week give her frozen blood worms and/or Brine Shrimp & she'll be super happy. I drop a pellet, wait until its eaten then drop another that way I can see how much they'll eat without over feeding. Mine get 3-4 pellets daily with one day fasting, on the days I feed frozen foods they don't get pellets. You'll enjoy having her, she'll get excited when she sees you & come to the side of the tank you're on. Oh & word of warning - you can't have just one, LOL.
