What's this little thing in my nano tank?

Sorry I'm referring to the worm looking like thingy with needle-like stuff on it.

That is a bristle worm. They are basically part of your clean up crew and wouldn't worry about it unless you have tons of them. Also be careful as they have a nasty sting if you touch them with your hands. I just leave mine in the tank until they get really big then i take them out with a worm trap.
