Swimming flatworms?

[SnakeCharmer]

Greetings all.

I do not have any pics to share and these things are so tiny that I doubt they would show up on film without strong magnification. They are flat, tiny, slightly broad in shape, swim by undulating like a ribbon, and difficult to see with the naked eye.

The tank is a FOWOLR so I am open to using whatever meds needed to eliminate them, unless they are harmless and actually beneficial in waste control.

Fish: Blue Tang, Ocellaris Clown, Fiji Devil, Flame Hawk, Engineer Goby.

The hawk shows no interest in preying on these tiny creatures.

Please help ID them and suggest the proper med. I had seen them in this tank several months ago and then I treated the tank with copper sulfate. I did not notice any more until just a week ago.

Thanks!

Epitoke ?

Epitoke ?

Not an epitoke because there are no adults in the gravel.
