Looks like bristleworms to me. Some people have a serious phobia of them but mine have never caused problems so I let them be. Someone on here and I can't remember who accidently grabbed one and had some gnarly looking spikes in their hand so just don't touch em'
I thought it was the infamous flat worm or something. I have several but mostly on one rock, and yes I almost pulled this one out. Thank god it is not something horrible. I could not deal with anymore tank issues right now. Thanks folks for the info. Just FYI the one in thee picture is about 10 inches long.
Go look at your tank with a flashlight after the lights have been out for a few hours...
...on second thought... Don't do that... :twisted:
I saw a few that were pushing a foot the other night... Until/unless they get really thick (Like finger thickness) I don't worry about 'em at all.. As far as length, they seem to be able to stretch quite effectively.
