Pineapple Vinegar Saga

So the pineapple vinegar making seems to be progressing. It's been about a week, and I had lots of mold at the top of my jar:

I skimmed all of that off, reduced the amount of actual pineapple, and transferred it into a sterilized spaghetti sauce/mason jar. And recovered with the coffee filter. My mold looked different than the mold in the pictures of tutorials I've seen. Mine is red; theirs was green/black. The fruit flies are getting pretty annoying, they've infested the entire house it seems. I've moved the jar from a shady spot on the kitchen counter to a cabinet under the bathroom sink. I don't know whether that will help with the flies, but I can hope.
