Pipe Organ (Tubipora musica) - Soft Coral The tile is a 1" square. Added to my system November 22, 2019. Picture taken ~30min before this post. Its name is Daisy. The cool thing about this species is that it is one of very few soft coral species that grow skeletons. The other softies with skeletons are gorgonians, that have a different type of skeleton.
