What's This?

[toast84]

I'm starting my first Salt Water aquarium and put in some live rock a few days ago. Today I noticed this. What is it? Is the coral coming back to life?

Is it the red like spiked growths ?
I have the same thing .
Not really worried about them . But I am curious .
I assumed it was some kind of calcified growth or coralline

I just learned something. They throw out long stringy filament things, yes?

No those are vermetid snails. Foramineferans are tiny animals that build structures like you see in that pic.

ah.. Ok. Well either way I've learned two things now. Thank you.
