differences: bristle worm vs eunicid worm?

[c_scherer123]

How can I tell a bristle worm from an eunicid worm?

I just started reefing, so I am not very good at IDing critters. I got a new piece of LR, I assumed the worms on it were bristleworms (fine by me as long as they don't pose for viewers), I gave it a 15min freshwater dunk and got rid of most, but I saw a few are still alive. I am now starting to have doubts, mine are bright red/pink and I read a few threads says bristleworms are usually more grey.

What are the differences to distinguish the worms?

Eunicid worms have tentacles on the front of their heads, around the mouth. Plus their bodies look more like a centipede's than a bristle worm.

Here's an excellent resource for identifying hitchhikers of all stripes:

Yes they are bad. Some are classified as detrivores, but I would not trust any Eunicid worms.

*sigh* It is an eunicid worm...
I have the rock isolated, what is the best to "gently" break it up to remove said worm? The rock was chosen for some nice fanworms, so a longer freshwater dip is out as the short one didn't work.

most eunicids are just detrivores. I have several in my tank. I wouldn't go crazy about trying to kill it unless it begins to eat zoas or something. The odds are in your favor.
