They attack everywhere, gills, fins, scales. They are like sucker fish in the way they act. Very small, and white/transparent. I managed to vacuum a couple off the bottom, pulled them out of the water and got some images and videos under the magnifying glass. I am working on posting them now. They act just like sucker fish, but they cannot swim, rather they squirm, and when they touch bottom they grab on like a sucker fish...Maybe even slightly striped, one of the two I caught had a striped effect to them. I doubt they are babies, even so the fish has been pregnant, they do look like the parasite. Hopefully you can confirm. They are smaller than the tip of a tooth pick.
And the parasites on her do seem to hang on like a sucker fish. And one thing I noticed about the parasite she pooped which was longer like a worm, it got down near the bottom rocks right before the filter sucked it in, I noticed it was squirmy until it got onto the rock and then crawled like a caterpillar...
