What is this on my oscars?

Also, if they are mites, they likely came in as a gill parasite. It is also possible you got them with some ghost shrimp that you fed.
Here is a link with a few avenues to pursue while trying to research what you have: Fish Parasites, or Just Scavengers?

My daughter put one under a microscope, granted it's not a real fancy one, and this is what it looked like...still no closer to finding out what it is...

The video on the substrate...those resemble seed shrimp. I see those in my shrimp tank. Google Ostracods or Seed Shrimp.

Mike - Those are like city rats compared to the ones in the previous vid. I've seen them in fountain and they were sesame seed size, though the ones in my tank are quite small (like this dot ".")
Sizes range from 0.2 - 30 mm as per this site:

Yea I see that now but if you look close there are much smaller ones in the video also. I was just hoping it was something to compare to and either rule out or confirm.

So I read the articles posted and seed shrimp say they have a shell, when my daughter put one under her microscope she said it was soft, didn't feel a shell. It does sound like seed shrimp, maybe they are too tiny for shells?

It is a soft shell. Think of a soft shell crab, not like a normal hard crab shell.
