I've never seen moldy antifreeze. What does it look like? I suspect you're seeing one of the many additives that settled out or isn't mixed well.

I think you're seeing additives that will mix in the engine. Those are things like water pump lubricant, corrosion inhibitors, and anti-foaming agents. Mold DOES grow in ethanol, which is alcohol. Antifreeze is alcohol too, but mold needs air to grow. If your antifreeze was in a sealed container, I doubt it's mold. Regardless, it's not going to hurt the cooling system.

Maybe a little bit of oil floating from contamination?
