What are these worms???????

[tanyaclick]

I found a bunch of these teenie tiny worms (not red or black fly larvae and not mosquitoes) in my pond. Here's what it looks like under the microscope. It's less than 1/4 inch. You can't see any of this definition without the microscope.
We've recently treated with dimillin because we thought we had lice. We're now going to do proform-C.
We've have 1 fish in a hospital tank for a couple of weeks as it had what seems like a carp pox breakout and we did find 1 lice on him.
Looking online this worm doesn't appear to be anchor worm or flukes or anything I can find.

Are they in a water sample or on a scraping from the fish? Could they be one of the life cycle stages of the fish lice?

It was in the skimmer under the filter media. Is it maybe some larvae?

It looks larval.

It looks larval.

They are probably the hidden marvels of nature that keep our ponds healthy.
