bristleworm?

[Feron]

well I found my first worm (came on a piece of new aquacultured rock)

Sorry for the bad picture..
Before I add it back into the tank, I figure I'd ask if he was ok..

 

[Feron]

ok, I just read a good bit about 'bristleworms'.
Seemingly harmless sorts of creatures for my tank, especially due to it's size..a good ident is still helpful, till then, it's the QT tank for this guy heh

I would agree it is a bristleworm and usually harmless if not beneficial to your tank.
