This is a really beautiful cristata hammer. With this species the 'hammer' part of the coral is rounder and more compact, also referred to as 'graph coral' . The polyps are shorter and it is less prone to send out stingers at night. These are farm grown and are incredibly healthy and robust corals with a strong flesh collar that extends far down the skelton. These have a marbled colouration with purple and green 'splatters'
