well, i found him in my Daphnia live food, really odd...ive got a reason to belive he (and the other 2!) may well be called Chaoborus, i noticed the link i put here has that in the name so i googled that.....however that says it may eat little critters that can fit in his mouth.....im not to sure what to do with him, probelm is when i google glass worm he looks nothing like them lol
