The Button Coral (Cynarina lacrymalis), also known as a Cynaria Coral, is a species of Long-Polyp Stony coral that thrives among the Indo-Pacific Ocean. They should be kept on the sand bed with moderate flow and plenty of space, as to not rub against rocks. They will accept carnivorous preparations and do well when occasionally offered supplemental feeding. Being an LPS, Angels, certain Butterflies, and other possible corallivores should be monitored when kept in the same system as the Button Coral, as they may be an easy target of predation.
