Is this a bristleworm?

[slitherbomb]

Found this guy just now and put him in a net so if it is bad, I could just throw him away. Is it harmless? The tank has just been set up and got the lr from craigslist. Thanks.

That is a bristle worm.

Is it ok to leave it in? Would they harm any coral(Sps mainly) or any invertebrates?

I have quite a few in my tank and they have never bothered anything. From what I read they do some cleaning up for you.

Alright then dumping him back in the tank then lol

I'v heard they are good cleaners, and witnessed this also. I hate um though, my tank is over run with hundreds of these and I wish they would just go away. I trapped a couple dozen but they seem wise to my trap and mostly keep clear of it now. A sixline loves eating them but I just gotta get better at keeping them alive with #4 to be added soon
