Chalice corals account for several different genus of LPS corals: Echinophyllia, being the most popular, Oxypora and Mycedium. Chalices are characterized by their flat base tissue and random dispersal of eyes/polyps. The base tissue can come in just about any colour or combination of colours imaginable. There are many high end chalice corals which are referred to as ‘rainbow chalices’, with intensely contrasting colours and patterns throughout. The eyes of most chalices are often a completely different colours from the base tissue, making them really stand out. Most chalices grow in a flat, disc shape, often encrusting the rock or bottom of the tank. Sometimes a different colour can be seen on the growing edge of the coral. Chalice corals are an excellent choice for marine hobbyists of all levels.
