not harmful if they are the normal ones almost everyone has. The loss of color on the base of the SPS most likely due to something else, like recently placed in a darker area, or a shift in water chemistry.

I've been trying to control my bristle worm population for a while, and predators include

6-line wrasse
coral banded shrimps
butterflies
and large damsels.
