Strange worm, slug thing friends or foes ?!?...

This 1 is about the length of pinky nail. Very thin tho. Had to zoom in on pic & video. Grabbed him out with coral feeder. Found another 1 swimming in tank like a slug does and caught him w a net, he was a lil bigger. Seem to have 2 tentacles in front and something else that made him hold into net as I was trying to get it off. Brownish stringy stuff on it as u can see with blackish body.. Looks like a snafu of worm, slug and who knows what else all mixed up in one lol

Any ideas????
