eunicid worm I assume?

Never had one in 15+ years of reefing but this sure looks like one?
Small only two inches long. Do they eat SPS? Had a SPS in decline could not figure out why, saw no signs of any pests on close inspection. Finally did a dip and this guy came out of some where. Does it mean I have more, anyone know?

Bingo, you're right. Not sure if the bother SPS but will wipe out zoos in no time. Good catch!

Eunicid I believe are just predatory.. they get big, have mandibles, will eat fish.

Better off with a mantis shrimp. I don't believe eucinids will harm corals.

I believe they generally live on their own, fortunately.
Maybe keep it in its own tiny tank, or in a sump? They get this pretty rainbow patterning when they're older.

Did it have the mouthparts? That sounds more like average bristleworms.
