Flatworm Suggestions

[EricR]

I've had these flatworms for easily over a year without any noticeable issues. *microscope picture and video below
Always visible on the front glass, along with copepods. (Maybe these eat pods?)
Population initially exploded but then dwindled and stabilized within the first couple of months.
They're really small, maybe 1-2 mm.
*came in on a ball of chaeto from eBay that went through 30 day observation first but, of course, never saw any in QT

Basically just curious what the more experienced would do here, with the following notes:
-- don't want to add any more fish
-- really hesitant to treat tank with any chemicals but open to researching any that are suggested (Flatworm Exit?)
-- I've heard Blue Velvet Nudibranch as an option but quite a bit of flow across the glass where I see flatworms so doubt the nudibranch would venture up there (but not sure)

*dinos in picture/video also but not asking about those here

As long as they are not overwhelming anything you can just ignore them. If there are too many of them you can use airline tubing to suck them off the glass. They like to congregate on softies and will irritate the coral when in large groups. When this happens you can dip the coral in question.

If it ain't broke, don't worry about it :)
Yes, they eat algae and copepods, so the population of flats and copes will likely ebb and flow...

Thanks for the tips so far -- feel free to keep opinions coming.
Airline tubing to suck them out seems like a good idea but "feels" unlikely to really ever eradicate all of them -- still will give it a whirl when I can.
