Bristleworm. Detritus eater and cleaner if uneaten food. I don’t welcome them in my tanks but many reefers love them

Agree bristleworm. Kinda ugly but cool at the same time. I let them live, my pistol shrimp seems to like them.

I third bristle worms. They aren’t good or bad for your tank really. They can be slightly beneficial for things like getting rid of old food or detritus so it’s really all personal preference on if you want to keep it or not - kali
