Is this a bristleworm?

[adarnley]

Hi everyone.
I am new to this amazing world of owning a marine aquarium. I have a noticed a new little visitor to my aquarium, through research I believe it to be a bristleworm and not the dreaded fireworm but I wanted to get some extra feedback!
Am I correct in thinking it is just a bristleworm and that it won’t actually cause any issues if left in my tank?!

Thanks all
