Id these worms and is this coral?

[Bogie]

Here's what I found yesterday, not sure what it is, so any ideas? If they're bad, how do I get rid of them?



My wife found these on another piece of live rock. I think they're bristle worms, but can anyone confirm? Also, if they're bad what's the best way to take them out of the tank?



Lastly, these have been on my LR for a couple months since I bought it. Are they some sort of coral? If so any ideas what kind. (See my new scarlet hermit crabs?)


Thanks.

Bristle worms, their good. That coral is dead, but I could have been an Acan, Mussa or a hairy mushroom.

I think the first picture is of a peanut worm but I'm not positive as the picture is blurry.

The pink ones are bristle worms.

Ok, so I've heard mixed opinions on bristle worms.
1. Remove them immediately: they are bad for any reef tank.
2. They are harmless; live and let live.

What should be done here?

Leave them be unless they get extraordinarily large. They're a necessary evil in a reef tank as they eat detritus and leftover food.
