I have never seen these in my tank, but I found this (and what looks like some juvenile ones) in a container of sand I had scooped out to transfer to another tank (it was then sitting for a week so all those worms are now dead and probably crawled out of those shells. Any idea what kind these are? I haven't noticed any negative effects on my coral so I'm hoping these guys aren't fireworms because I bet there are more of them. It's hard for me to tell. That large one is half an inch long at most.

I have found some of these in my tank. Should I remove them when I can or they ok to leave in?

In my opinion they are the best cuc to have in the tank. They will clean up fish turds and extra food all day! I have tons of them. They never bother anything healthy and living.

That’s the standard model bristle there bud.
I still don't get where the fear of fireworms came from....they are almost literally never seen in the hobby and their behavior is extremely conspicuous so you wouldn't have to guess what it is. Plus, regular bristleworms are absolutely COMMONPLACE.

I guess this is part of the fear and paranoia surrounding real live rock these days. Weird considering the hobby we're talking about, but a fact. (Without live rock, IMO we just have saltwater fish tanks with coral.....not really reef tanks.)

The fact is has a millions legs, and most find them feeding on dead creatures makes them think the BW killed them. That couldn’t be further from the truth.

Fact is the creature that they are going nuts on died or was dying long before they took them out! Have spent countless hours watching my tank at night. And I do mean countless hours! Haha! Never have I seen them eat or attack healthy creatures of any kind! I spend about 5-6 hours an evening messing with the tank.
