Thats a bristle worm.They are scavengers and will eat dead fish or clams .I personally don't like them in my tanks.The bristles on the side of body is sharp and stick you in the skin .

Looks like a regular bristle worm to me.

Yup, that's a big one... would definetly remove as the larger ones can be semi predacious (and not to mention, can pierce skin). The classic removal method is to use a pair of forceps and a flashlight at night and go hunting.

I would not waste the time or energy removing. Good member of the cuc crew. Population numbers based on available food source, so do not over feed.

I've always considered them a good member of my CUC as well. Never had any problems with them.

I would agree with the above regarding smaller bristleworms.. once they get larger; like yours (which isn't that big compared to many), you may start to see issues

In my experience they are fairly beneficial, until they get bigger. I had some in my 30 g years ago that were over 6" long. After I got stung by one while moving some rock, I got a bristle work trap and cleaned them out. Felt like my hand was on
