Yeah, sorry about the picture, damn thing was moving so much, I took 6 pics and this was the best one. Couldn't tell if the movement was its own, or just the water flow. Thank you for the Spaghetti Worm suggestion. As a result I did a little searching and found that I have either Spaghetti or Hair worms. Also from my research these look to be harmless, even beneficial detritus eaters? Am I right on that?
