The Cynarina Coral, Cynarina lacrymalis, also known as the Meat Polyp Coral, Doughnut Coral, Tooth Coral, Cynarina Doughnut Coral, Teary Eye Coral, Flat Brain Coral and Knob Coral, is a great beginner coral for its ease of care and interesting morphology. It features a single, large, translucent polyp that may easily rupture. It is peaceful and best kept on a thick sandy substrate. They will readily take a carnivorous diet on top of their photosynthetic habits. The Cynarina Coral is a wonderful addition to most tanks as it is incredibly flexible in what it is able to be kept with.
