A few days short of a month ago I got a female betta (picture below) and wanted to know if she will change to a darker color. I made sure to get the youngest female I could find in order to keep her longer. She has recently gained a bluish tint in her fin a semi silver looking upper belly and a few specs of what appear to be color on her side. Just wanting to know if my little chicky will surprise me one day with some beautiful colors.
