The Cynarina Button Coral is a large polyp stony (LPS) coral that is also commonly referred to as Cat's Eye, Tooth, Doughnut, Teary Eye, or Meat Coral. The Cynarina Button Coral resembles an artichoke in appearance, it is one of the largest single-polyped coral found in the wild. It's coloration can vary from different forms of bright vibrant pastels to more drab variations. The Cynarina Button Coral is non-aggressive in nature, but like most corals, requires adequate space in which to expand sweeper tentacles and such in order to feed. In the case of the Cynarina Button Coral a space large enough to allow the coral to expand to twice it's size is required. Compared to many corals available on the market this space consideration is very modest, which allows for a variety of placements for the Cynarina Button Coral within a reef aquarium. The combination of both its hardiness and its ease of placement make this coral an excellent choice for beginning reef aquarists.
