I know this is a Bristle Worm and I started out with a couple of these on a piece of live rock I bought over a year ago that I put in my sump and they have apparently made it into my tank. I don't really mind since they only come out at night, but I was doing some reading and apparently they are not all good to have so I am wondering if this is a good guy or a bad guy???
Any comments are much appreciated!!! ;Happy
