That’s very interesting! I would never have known.She suppose to be blond female with red fins. But when bred in mass reproduction at a fish farm, there's hardly some selecting (culling) involved. Because of the lack of quality check at such fish farms, you'll notice that there will be specimens that are less red in their fins. Doesn't mean she's a female guppy of less quality. For a lot of people like this look. But it does differ from how it actually should be in this strain.
