Faviids are a very large group of corals which includes many diverse species. They are well represented in many habitats over a wide geographic area. Some easily recognized species are often called moon and closed brain corals. Many Faviids are very long lived corals and important contributors to the reef building process.

The various species of Faviids grow into every imaginable shape. Common species are often boulder-shaped, massive or encrusting. Uncommon species can be branching or plating. Faviids occur in nearly all colors but they are often shades of brown, green and red. Many species can display an unpredictable, mottled pattern. The corallites are commonly brightly colored and contrasting to the color in between corallites.

It is difficult to generalize the care requirements of such a large, diverse group but a commonality which they share is a preference for strong water motion. Light requirements are species specific but massive forms often prefer strong light whereas branching and encrusting forms prefer intermediate light. Faviids have polyps which are aggressive feeders of small to medium sized meaty food fares.

Massive encrusting species are best spread by encouraging encrusting growth. More delicate branching and plating species can easily be separated by fragmentation with a cutting tool. Growth rates are greatly improved with strong water flow and regular feeding.
