These really creeped me out. I soaked the plants in tap for a few hours and they died, then I stuck the plants in another container of treated tap to make sure any eggs hatch and I can get rid of those too. I don't want these in my tank, even though they may be good. They could be tubifex worms, but I have no clue really. They look darker than those. I don't know though, new to this.
Forgive me if I did something ignorant. I just don't like creepy crawly things lol.
