fireworm

Found white cleaning out algae reactor, what do you guys think? Got him in a bucket rn . Aside from amphipods it was the only thing that stood out in the reactor

It’s huge. I saw it when I was rearranging my rocks. I don’t know if it’s a bristle worm or fireworm

While I initially thought I had gotten rid of them, over the months I have found out that I have fireworms, clam worms, and medusa worms living and thriving in my main system. Some have been slightly more "benevolent" than others, but I should probably take steps to try to eliminate them. Here...

Just wanted to verify if these were fireworms. Found a bunch underneath a clove rock I took out to clean. Any worry with corals or to look out for with more of them?

Some kind of worm in my tank exploded with 100s of parasites. My power head was off when I noticed it. I don’t think it’s having babies. I’d be surprised if it survived. Any ideas? here is a YouTube video I uploaded of it https://youtube.com/shorts/odZDl0-FtXE?feature=share

Pulled this dude from my new (2ish months) refugium and just want to make sure I wasn't dealing with a Fireworm. I am super new to the hobby and have heard many good things about bristleworms, and many bad things about fireworms. He looks to be a normal bristleworm, but just doing my due...
