Bad or Good?

[Reef GE]

Is this a normal bristleworm or something bad? A little over an inch long. He was in my rock.

They can eat up detritus in places other critters cannot get but they are ugly. Looks like a regular bristleworm but I could be wrong. Those things can get big and scary. I have a few that are about 8 inches.

He has white fuzz all along his body. Doesn’t show in the picture.

Fire worm by the looks of it.These you will want to try and eradicate. They can wreak havoc on hard or soft corals. I had a nice colony of red trumpets get massacered and I'm pretty sure these guys were the culprit and also lost some nice blastos..I started dipping after this..was a lesson learned. I actually removed all the frags and dipped them and added a melanarus wrasse.

And that's why I refuse to have any of them in the tank. Good or bad they're ugly and a pain one way or another. Lol

There very well could be. Eggs can hitchike in on frags. I removed 3 or 4 manually, one evening I shined a light in the tank and discovered more. The wrasse seemed to have done its job. Also Arrow crabs are known predators of Fire worms.
