Can’t see vid anyone else ?

Not the Trochus, nor the copepods.

They kind of look and move like some kind of flat worm.

Anyone?

Can't help with ID other than to say they move much faster than the flat worms I have. Mine move around very slowly. Also mine are not as long. The smaller ones I have are almost round.

Those dont move in typical flatworm ways. Not sure exactly, but doesnt look like any flatworm ive ever seen.
