| Care Description | When it comes to diversity, it is hard to think of a more visually diverse group of corals than Favia. These brain corals develop multiple growth forms and come in just about every color and pattern imaginable. The diversity however is a little bit deceptive. Have you ever got the feeling that the term Favia covered a lot of corals that looked somewhat different? You are not alone.Favia brain corals were one of the largest categories of large polyp stony corals in the reef aquarium hobby. At one time there were nearly 100 species of Favia but now that number dwindled down to only two, Favia fragum, and Favia gravida, both of which are Caribbean species. That means that there are essentially zero Favia brains in the reef aquarium hobby because stony corals from the Caribbean are illegal to collect. So what happened to all these species of Favia? Coral taxonomists over the years reclassified them into other genera as more information was uncovered. Most of the corals that were once classified as Favia are now Dipsastraea, Goniastrea, Coelastrea, or Favites. |

General Description
Favia corals are known for their visual diversity, displaying multiple growth forms and a wide range of colors and patterns. Although once comprising nearly 100 species, only two species, Favia fragum, and Favia gravida, are now recognized in the Caribbean. Taxonomic revisions have reclassified many former Favia species into genera such as Dipsastraea, Goniastrea, Coelastrea, or Favites.
Demands and Hardiness
Favia corals, like the Reverse Prism Favia, require low to moderate lighting, with an optimal range of 50 to 100 PAR. They are sensitive to excessive light, which can lead to bleaching. Water flow preference for Favia is low to moderate, with tolerance for various flow patterns. Providing a balanced flow helps prevent debris accumulation and potential coral damage.
Lighting
Favia corals thrive under low to moderate lighting conditions, typically ranging from 50 to 100 PAR. They can survive in dim lighting but are intolerant of excessive brightness, which can cause bleaching. Adjusting lighting intensity is crucial to prevent stress and maintain the health of Favia colonies.
Water Flow
Maintaining a low to moderate water flow is essential for Favia corals, as excessive flow can damage the delicate structures. Balancing flow patterns to prevent dead spots and detritus accumulation is crucial for the health of Favia colonies. Periodically shutting off flow during feeding sessions allows the corals to consume food efficiently without wastage.
Feeding
Favia corals rely heavily on their zooxanthellae for nutrition but benefit from direct feeding as well. They consume zooplankton, Mysis, and various powdered or pellet foods in small sizes ranging from 0.1mm to 13mm. Offering a mix of meaty foods like shrimp, fish, and squid enriched with vitamins and essential fatty acids supports the overall health and growth of Favia corals.
Propagation
Propagation of Favia corals varies among species within the genus, with some showing rapid growth rates while others are slower. Despite being able to heal well from cutting, long-term commercial aquaculture of Favia species faces challenges due to differing growth rates. While most Favia corals can be readily fragged, certain species may not be ideal candidates for extensive aquaculture projects.
Localization & Habitat
Favia corals are commonly found in the islands of the Indo-Pacific region, including Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. Their habitat consists of shallow reef environments with appropriate lighting and water flow conditions to support their growth and development.
