They kind of look like bristle worms except for their heads look different at least compared to the ones I have in my tanks.

Are they good or bad?
 
I'm assuming since it is a scavenger it is good!
 
Thank you!

For the benefit of the entire club, I have copied below, the PM that I sent to Arthur in response to his inquiry.

Perhaps it will put your mind at ease to know that in my 17 years in this hobby with dozens of my own tanks, adding numerous types of organisms, always leaving strange critters in my tanks, adding uncured LR fresh from the ocean, I've never had a coral eating worm and to my knowledge never had a problem with Isopods. I'm not saying they weren't there. I don't know, but I've never had any organism that I could not take care of in one way or another.

We should recognize that some of the living things introduced into our tanks do not survive. Many organisms soon die because the conditions, mostly food, are not right for them. Flatworms, Aiptasia and Red Bugs are the worst and we know how to control or eradicate those.

I allow and even encourage diversity and believe my tanks have been so much the better for it. A few years ago, when I was growing coral for part of my income, visiting hobbyists loved to sit and examine my tanks. They would often comment on the wonderful abundance of life in my tanks compared to others. I must have been doing something right. Smile 

Keep your arms and hands in the tank and enjoy the ride.

Mark

Besides, that crazy long worm from Oregon does not seem the same type of worm as in Arthur's pic.

Rob Toonen says, "Polychaetes are an important, but much maligned, part of a healthy reef environment."

He even pictures this worm the Scavenging polychaete Eunice antennata, that has antennae not unlike those on Arthur's worms.



Maybe I should add that, because of the way I create my reef systems, no skimmers, in the sunlight, encouraging algae growth and herbivores, I may be a little different than the typical hobbyist. The pristine manicured tank with ultra clean rock and sand may not handle these scavengers as well. There just isn't anything for them to eat, so they crawl out, taste the coral and say, "Hey, that's better than nothing."
Just a thought.Embarrassed

Mark, I fully agree with you. I'm relatively new to this hobby but feel that diversity only helps a tank. I have no sump/skimmer/refugium ect. I have done only 1 water change in the 7 or so months that its been running. I rely on, and encourage, scavengers and macro algea and other "things" to help keep a balance. I want a tank full of life. A "busy" tank is much more interesting.  Just my $.02.
