The Favia Corals are large polyp stony (LPS) corals often referred to as Moon, Pineapple, Brain, Closed Brain, Star, Worm, or Honeycomb Coral. They are the most common and prolific coral in the world, and are very similar to the genus Favites, sharing many of the same common names, and sometimes being very difficult to differentiate. Favia Corals are found in various color forms and polyp shapes. “Pineapple Coral” is the name commonly given to those that have smaller circular patterns. The Favia coral is a very easy beginner coral that requires low to moderate flow and light.
Water Conditions: 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.023-1.025 Supplements: Calcium, Magnesium, Strontium, Trace Elements Placement: Bottom to Middle.
Both Favia and Favites are referred to as Large Polyp Stony (LPS) corals which means they grow a calcium-based skeleton upon which individual polyps live as one communal animal. Each circular polyp is oriented around a central mouth (or multiple mouths, depending on the species). At night, or in response to feeding, tentacles may emerge from around the mouth which are used to catch and consume food from the water column. Most members of this group will grow both laterally and vertically. Over time they will begin growing and encrusting onto the rock they are resting on. If given enough time, they will eventually become completely attached to the rock they sit on and will sometimes even fuse separate rocks together. These genera will also mound higher by layering their skeletal structure on top of itself. Some species create dome-like structures that have the shape of a brain, which is why their common name is “Brain Coral.”
