Hi All, new to the hobby and was wondering is this worm is good or bad to have in the tank?

Hopefully you have already caught it and it is no longer in your tank; nuke it

Thanks all it’s the second one I have caught in two days. Thought they were bristle worms. Yes out of the tank but I’m afraid there is more. I have dipped all my corals I have put in. Could of these been eggs that hitch hiked? Anything I can do other than removing them when I see them?

There are many, many different species of worm that we as hobbyists call 'Eunicid' (which is just one genus). They all tend to get a bad rap because of the well known carnivorous Bobbit Worm, but in reality many are harmless omnivores, detritivores and herbivores. Some will eat coral and these obviously need to removed.

As an Old School reefer I personally welcome these little freebee unidentified oddities since they add biodiversity and interest, but I also keep a close eye on them. I will only proceed to elminate them if they cause damage in the system.
