What Are These White Spots?

[BigEZ77]

Hi All,

I got this hammer coral a couple months ago already attached to a rock. Just recently noticed little white spots all over the rock and on the stem of the hammer. Any ideas what it might be?

Thanks,

Spirorbid worms most likely.

Your hammer coral has already "attached " to your rock after a few months?

 

[BigEZ77]

Spirorbid worms most likely.

Is that a bad thing?

Heath, it came glued to the rock from the LFS.

No, they're just harmless filter feeders.
