I just recently purchased a betta fish from Petco and picked her because she was mostly a whitish/pinkish tint with a few red spots on her head and gill area. She has very pretty fins and my male betta nearly jumped out of his tank when I "introduced" the two..
I assumed the red was just her coloring and perhaps the white/pink was just color loss from mistreatment at the pet store. They seem pretty symmetrical.. but after looking at some pictures Im not so sure anymore so I figured I'd post a few pictures and see what you guys think. Keep in mind she acts 100% normal, is eating and actively swimming around her 5.5 gallon tank! (FYI.. she's not upside down in that second pictures.. its just me being terrible with a camera.)
