Bristle worm help

[Jordan92595]

I’m having a major bristle worm outbreak which I don’t necessarily mind because I know the benefit of them , but I’m starting to see some negative impact in my acans which I believe is due to the worms.
My acans have always been very healthy but for the last 4 days they have not come out at all.
I picked it up and it was covered in worms underneath it. I have had a trap in the tank for the last 3 days to help rid of some of them but I haven’t seen any large ones just a tremendous amount of small ones
I did not know there are so many different types and some can be very harmful. So I’m wondering what kind I might have and if they are okay in my tank or if I should be trying to remove all of them.
Picture is from one night with trap and I have had the same amount in there every night so far. This was my father in laws tank that I homed and he was a very heavy feeder. I cut back on the feeding a whole lot.
So my question is are they a safe kind and should they be negatively affecting my acans like this.

Large outbreak suggests possible over feeding. Cut back foods and siphon more frequently
A couple arrow crabs will take them down

I put an arrow crab in there but I’m reading they nip at corals so I’m wondering if he is what is affecting my acans ?

Possible. Test params - it may be completely unrelated.
Bristleworms may irritate coral in large numbers, though it’s the fireworms you have to look out for.
My tiger pistol shrimp destroyed all of my bristleworm.

I had a bad outbreak after dumping some natural seawater in the tank. At first, one or two worms. Later, hundreds. Traps did not do the trick. I added a Red Coris Wrasse. Within a few weeks all the bristleworms were gone.

And the pictures I have don’t look like fire worms do they ?

I have a melanarus wrasse I just added a week or two ago I haven’t seen him grab any though

Those appear to be bristleworms to me.

I've never understood the arrow crab thing.... you have a harmless detritivore that has bloomed in population because there's no reason it wouldn't and everyone tells you you need an opportunistic predator crab to control it, when this crab is much more likely than the bristleworms to harm your reef.

If you want less bristle worms, feed less and feed cleaner. They cannot bloom without an abundance of food.
