At feeding time tonight this ugly thing emerged. We scooped it up with the turkey baster and put it in a cup to photograph.



What is it??? After looking in our books, we are leaning toward hair worm, but also considered medusa worm and spaghetti worm. We've never seen any of those in person, so if you know what it is, or even what it isn't please let us know so we can rule it out and decide whether this should be thrown back in the tank, moved to the sump, or thrown out with any others being hunted and destroyed.
