Tiger pistol/yellow watchman/bristleworm

[FLricordia]

I was doing a little maint. in my refugium where I have a 1" Tiger pistol and a 1.5" yellow watchman goby living. I accidently turned one of the small rocks they have a tunnel under and found them there-with a 2.5" bristleworm.
There didn't seem to be any conflict. They were all actually huddled together.
I had known about the bristleworm (don't know what kind-very light pink and white) for some time but haven't thought much about it as I haven't seen it in weeks.
Strange partnership! Anyone have any thoughts on what is going on here? I thought for sure the bristleworm would avoid and be avoided by the others. I will try and get some pics of it in the next few days.

That's quite a group you got there! My purple lobster has a couple "buddies" living with him in his cave. Its funny in the middle of the night they will come out and feed together and in the morning they will go back into their cave. I have never heard or seen a fish and a shirmp living with bristrleworms though I would love to see a pic!
