My opinion is the same but yes bristle worms are a good cleaner. I personally get rid of them though due to the slim chance of accidentally touching one.
I will try and net it when I get the chance. I asked about it because this is the pic and caption from one of my books:
"A model for certain sci-fi movies."
Those long handled corals grabbers are great to just pick em right out. I have some in my fuge, max 4 inches long though. They're roommates with all my pods. . Not a big deal, just when I see the chance to get them, I do. As they spawn a lot so when you can, just flush them!
