what species of polychaete?

[Copepod]

I have noticed some upset mushrooms, my cleaner shrimp died, and my fire goby has been acting funny. All my parameters are golden. Tank is well established and today I think I have found the possible problem.

Please help, thanks!

In the picture the worm is trying to get at my bi-valve

looks like a bristle worm. Not usually problems

There are thousands of types of bristle worms, yes a majority are harmless and beneficial.

But...
Something is upsetting my fish and corals, there is no doubt. Other corals in the tank including snails are fine and are showing no signs of stress. I have been testing my water vigorously and checking temperature.

So, it should just fix itself?

what are "golden" parameters? we need to know everything to try and "get to know" your tank. It's insane how many things can be detrimental to a reef tank.

Agree with this 100%. Something else is going on. A bristle worm is extremely unlikely to "upset" anything in the tank ~ especially fish, unless they are dead/decaying.
