Are these bristle worm eggs?

[gcorwin]

I have noticed more than one of these clusters, They are right below a Hammer coral but I doubt they are polyps. I do have a bristle worm problem and am working on reducing them, but I was wondering if someone could identify these.

In my tank (32 gal biocube) I have two each of clowns, damsels, green chromis, and one royal gramma. Plus variety of asteras, conchs, turbos, and a sand shifting sea star.

TIA

Pithos Crabs or manual removal are probably your best option. Emerald crabs work good but can go rogue and start pestering LPS.
