Are these guys pests?

[Alec Berger]

Hello,

I have been battling some different coral ailments, but I thought most everything has been fixed and things are looking better. Yesterday after dark, I took a flashlight to observe my corals at night and saw all these guys swarming over my LPS (Duncan, Hammer, and Acan). Do these look like normal copepods or could they have been what has been causing some of my problems?

Also, I noticed quite a few bristle worms writhing about near my coral's heads. Are these guys known to irritate corals as well?

Besides the red/brown spot, is the rest of their body more translucent or is it more white?

They look a little suspect, but unsure. You could always do an interceptor treatment if your on the fence

I would say they are more translucent than white.
