Thanks guys. So that's where that piece of "Hubba Bubba" went!
I have Grant to thank for the original two branch, three head chunk o' hammer. Somehow it managed to survive all the trauma to which my corals have been subjected.
It's growing more rapidly now. Interestingly, to me anyway, while it was one coral with two branches originally, one of the branches had all the green coloration, and that seems to be the case still today. I fragged off the branch without any green and that portion is growing great with 6 or 8 heads now but continues without green. Genetically identical, same piece of coral in same tank, about a foot apart, with different coloration.
