What a cute girl! And I agree with Pam, that name is priceless.

Hard to tell from the photo but Pearl seems to look a lot like my pink and lavender girl, Consuela. I got her to match Esteban, because she was also very pale when I got her... obviously she is not nearly as white as he is any more, she is really colouring up and even getting these REALLY bright metallic/neon blue streaks at the base of her tail! It's amazing how they blossom with proper care and nutrition...
I can't wait to see more photos of your special girl, and so happy that she was rescued by someone that takes such good care of her.

If only all bettas were so lucky!
