Twisting Worm - Need ID!

[Clemquat]

We decided to look around our fish tank tonight a few hours after the lights went off. i found 3 small worms, no longer than 0.5 inches, twisting and swimming around the tank. We caught two with the net and on managed to get caught IN the net and didn't make it. I put them in a measuring cup due to the lack of anything else to put them in... I have a couple pictures and video of them too. Two of the worms were black and one was yellow/tan with a blackish head. Are these good or bad??? They're going to stay separated until we can figure out what they are.

Hi Clemquat! We're not really sure what type of worm that is but we had "Cluster Dusters" at one point. They have a soft mucus tube and we accidentally broke one of the tubes. The duster went swimming in the tank after its tube broke and looked quite similar to the one in your video. Nice find and nice video!! (We need to learn how to make/post a video)
