The Favites Corals, along with the Favia genus, are attractive large polyp stony (LPS) corals. The Favites genus can sometimes be the more brightly colored of the two, but both groups come in pretty greens and browns, yellows and creams, and there's a slight chance of orange/red tones. Mixes of those colors are also seen with their "walls" being one color, and the calices "centers" being another, making for very attractive reef tank additions.
The Favites Coral is typically confused with the Favia genus, but it is actually quite easy to tell them apart with a little practice. The walls of the corallites, the raised areas in which polyps reside, are shared or fused in the Favites species, whereas the walls of the Favia genus are not. So when the tissue is recessed at night, on the Favia corals you can see two "sets" of walls between the calices (centers). Besides being fused, the walls of Favites Corals are also higher and they are shaped more polygonal and uneven.
In the wild, colonies of Favites Corals are flat, dome shaped, and massive. They can get to over 3 feet (1 m) in diameter. Some common names these corals are know for are Pineapple Coral, Moon Coral, Brain Coral, and Larger Star Coral. They are sometimes incorrectly called the Closed Brain Coral. This is actually a Favia name, which the Favites Corals resemble superficially.
The Favites genus is easy to care for as long as there is proper lighting, water movement, and regular feedings. They are an excellent choice for both the beginner and the advanced aquarist. Once placed in the aquarium, if left undisturbed for several months they can attach to what they are set on, and become a pretty and natural focal point in the aquarium.
Favites Corals have been propagated in captivity, yet propagation takes a long time, so they are still being collected from the oceans reefs. Favites Corals are also a little harder to frag since you cannot cut between a shared wall, you end up with damage to the surrounding calices . All that said, the Favites species are relatively easy keepers, and a great addition to any aquarium!
