Spline9- Thank you for the pics. Mine don't look anything like that. In your first pic, where they are closed, not even close. There is no soft tissue to make up the polyp 'stem'. All there is, is a calcified skelaton like Dana&PJ stated. And about a third of them came white. I will keep it in the tank, feed it like usual. If there is the slight chance it may come back. As for aclimating, I too use the drip method. The other corals are doing great.
