Answer 1

You are correct, that is a fungus on the old food particle, BUT the good news is that's a particular type of fungus that only grows on dead material and poses no threat at all to your fish. No need at all to worry or to continue treating the tank.

Answer 2

I would not worry about the fungus, but it tells me that you are overfeeding. You need to cut back on the food, and it won't be floating around until fungus grows on it.
