I have probably 5-10 of these worms in my tank, ranging from maybe 3" (visible length of body, not entire worm) down to thinner than a toothpick. While gross, they are kinda cool to watch creep out of their hole or shell tunnel and snatch food, then snap back into their burrow. They are lightning-fast when they retract. But this will only amuse me if they never start snatching fish. I've seen some close up pics of eunicid worms' jaws, and they're no joke. Is there some size threshold that I should start to worry about removing them to my sump in order to prevent fish murders? Thanks!
