i caught it. I shined a torch on it to take a pic, and the worm got very irritated running around in the tracks then i moved blue off the glass, he retracted his tentacles and i tried to brush off the worm, it came off and i caught it. blue looks pretty good to me( please look at other pics at this link to view the chase and the worm after he was removed. ) Not to be wasteful i fed the worm to my trigger(in another tank) as i no longer trusted it in this tank.
