Worm ID

[pw9988]

I shut off my pumps to feed the corals and found this worm swimming quickly across my glass. I sucked it up with my feeding dropper and put it under the microscope. The length is maybe 10mm extended. The only picture I found online similar to this worm was a post from a different reef forum where it mentions that it's a bobbit worm--yikes!! However, when I google bobbit worm, I don't see anything else alike. Hoping someone could help ID this #reefsquad Thanks!

only 10mm? What kind of substrate you got? Could just be a little worm in the sand that is helpful for the system.

Yes, it's not that long. My substrate is crushed coral.

The Dorvilleidae Worm is a smaller relative of the bristle worm grows to 3 inches long. These worms are characterized by the sickle-like jaws and the hook-like antennae (as you can see in your pic). Dorvilleidae worms feed primarily on algae and are not considered a threat to the reef aquarium.
