Bristle Worm Hitchhiker?

[guentherjessica]

Hi all, my first post here so bear with me. relatively recently have had a 37 gallon going for about 2 months. I started with some great live rock but discovered what I think is a bristle worm. wondering if i should let him stay or remove immediately. He comes out during feeding time between 2-3inches it looks like maybe longer stretched out.

Up to you. Some people buy them to introduce to their tanks, others will nuke them. Personally I don't like them, rather not have to worry about getting stung when moving coral around. They are a good part of the cuc but pose a risk to your fingers lol.
