[cwickham]

Hey everyone.. im new to this reef business.. but tonight i was looking in my tank with the red light and saw all the usual things.. accept this time a saw a thin brownish worm.. no brissles and it looks like it sucks its whole head against the LR, it hates light and will tolerate it even less then the brissle worms

anyone have any ideas what this thing is?

thanks

Could be a unicid/bobbit worm or spaghetti worm. A picture would help. Most worms are good for your tank with a few exceptions. Even bristle worms serve a purpose.

HTH.
