Something you might not know about that coral of yours. It looks a whole lot like a frogspawn that died. And then the skeleton spawned babies. There's a fancy science word for this but I forget it. LPS are known for the phenomenon. If that's the case, those small corals will drop off the main skeleton as they grow to be their own coral. And the original will be a baby coral factory for some time.
It is one of the coolest things in LPS keeping in my experience. I had a fungia skeleton that would do this and I LOVED having baby fungia all the time.
Good luck with your coral!
