Bristleworm?

[Saaqib_Ansari]

Hi I’m pretty sure this is a bristleworm

are they meant to be this big, can it be dangerous at all to coral cos this one is built like a pokemon

I saw a 4 inch one in my tank and it hasn't killed a fish (yet) it won't touch coral from what I know. They may kill small fish when they get big so you can create a trap to catch them if you're afraid of that.
