Tried to do a search but I couldnt find these guys. I was scrapping my glass and these guys ended up on the scraper. They have been in the tank for a while, just got around to posting the picture. Fish and coral dont seem to be affected, but I'd like to know if i need to do something sooner rather than later. I was thinking they were bristle worm babies, but several people have told me that it is VERY unlikely. caution, these photos are around ~5mb each http://nevadahi.com/site/images/DSCN1070.JPG http://nevadahi.com/site/images/DSCN1071.JPG I looked here http://www.xtalworld.com/Aquarium/hitchfaq.htm but i didnt see anything that remotely resembled them.
