Bristleworm?

Or fireworm?

Bearded Fire Worm. It's a type of bristle worm. Eats coral. I would remove it.

 

[QuinnLee512]

Ahh crap. How do I remove them? I removed a rock from my tank and noticed them under the rock. I assume there are more in the tank.

I do have a melanrus wrasse. Hopefully he'll take care of them?

That's the plan. Question is how? Time to Google for natural predators.

Carefully.
Wrasses will not touch these but arrow crabs will otherwise make yourself a simple trap with a soda bottle and bait with a piece of shrimp as pictured below

Or fireworm?

Definitely not a fireworm, those ones are much greyer in coloration. It’s probably just a common, beneficial bristleworm; the bristles appear much brighter outside of the water, making it look like a fireworm. Do you have underwater pictures?

It also looks more like a normal bristleworm to me. Do you have a picture of it in water, especially of the head of the worm. The easiest way to positively ID a bearded fireworm is by the caruncle on its head.
