I thought that too, that it might have been a spawn, but I don't know, it's in spots where current wouldn't allow something to "settle" without being blown away, so I'm still not sure.Most likely a spawn rather than polyp bailout. Lazy’s Corals had something similar happen.
I had to let them grow a little befor I was 100% sure it was the B.N.
I was watching a macna talk with Richard Ross about coral spawning, and my system doesn't really qualify for spawning, other than it gets total darkness every night. But he also said they don't know exactly what makes coral spawn they only have a good idea of what it takes.
Thanks for sticking with the thread
