This is a white and blue female HMPK from a spawn of a turquoise marble male and a gold female. This is a pet-quality fish that should not be used for breeding due to the asymmetrical scaling on her sides. She is very pretty though, and would make a wonderful pet. If you have never had a pet female betta, I would recommend it!
Looking at the photos you can see the pale gold shining through on her fins and face
