Can anyone tell me what this is on my torch coral?

[jaysreefs]

Hey,

I was wondering if anyone knows what this may be?

They don’t move at all and it’s on the skeleton and not the meaty part of my torch coral. Took this with the lights out which is why my torch is closed. When lights are on it opens normally.

I added this to my tank about 2 weeks ago and dipped it before adding it.

I would toothbrush them off

And scalpel off those snail shells

No, I don't know what they are
