I agree, i started my tank out with all dry rock and put 1 piece of LR in for "seeding". I noticed about a month ago a bristleworm about 10-20cm creeping around early one morning. In the last week i have seen my Blue tang and a Zebra Dart fish both swimming around with bristles sticking out of them.
The Tang was near the tail while the Dart fish was all the way down it's side.
Neither of them seemed to have any reaction to it but my fear would be if they got those bristles on an eye ...

I have a big one sitting underneath a rock. I could get it out any time I wanted, but I choose to let it stay.

You poke at yours and I bet it just curls up right? No malice in it at all. All it does it come out at night and look for uneaten food etc.

I think these ones are OK. BUT, mine, probably like yours, has gotten too big for the tank. Hence, the best they can do to hide is literally hide underneath a rock. They are too fat to slide inside the pores within the rock.

I will eventually remove mine and unfortunately kill it, but only because it's too big.

I consider them as a great addition to the tank - I am often somewhat dismayed when I see ignorant people (primarily on Facebook pages) claim that all bristle worms must be destroyed by whatever means.
I know they are good for the tank but wouldn't they need thinning out sometimes, i find they get so big and so many of them

holy cow, every have any of your fish get tagged like i described above?
No, never. Blue tangs like to hide away in the rocks of a night time so that could be why yours ended up encountering a bristle worm.

What do Dart Fish like to do when the lights are off?

On or off they are always burrowing in the sand under rocks. Having said that they are out more now i have lyretails in the DT
The don't bury themselves either, they just move a heap of sand to make a large hole. This could be because i don't have a deep sand bed, 2-5 cm at most

The way i set my rocks up i have 4 base rocks for each island of rocks to make a cave and certainly on one of them they have moved all the sand out from within the cave as i can see the acrylic sheet i have the rocks sitting on to protect the glass.
I suspect this is where he got tagged by the worm

My royal grammer shares its cave with a few worms, i can tell when it's had a rough night; it usually has spikes coming out of its face :)

I say leave them, they are part of the clean up crew and form part of the biotope.
