Fast swimming worm following torch

[Gavin Noy]

Last night i had a quick look round the tank with a torch and out of nowhere this 1 inch, thin, very wiggly worm followed the light. Because im having a nightmare with dinos, and torch coral mites my patience is waring thin with problems so i led it to the bottom edge and killed it with my glass cleaning magnet. If there are more is it something i should be trying to remove?

Pictures or should I just use my imagination?

Pictures would help but it almost sounds like a nematode to me. Does it seem to undulate when it swims?
