| 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 renowned for their visual diversity, showcasing various growth forms and colors, although the term "Favia" now mainly encompasses Caribbean species like Favia fragum and Favia gravida. Originally, there were almost 100 Favia species, but taxonomists have reclassified many into other genera like Dipsastraea, Goniastrea, Coelastrea, or Favites.
Demands and Hardiness
Favia corals have moderate lighting requirements, thriving best in low to medium light intensities ranging from 50 to 100 PAR. They are sensitive to high lighting and may bleach if exposed to excessive light. These corals typically prefer low to moderate water flow, but they can adapt to a wide range of flow patterns. Balancing the flow is crucial to prevent detritus buildup or coral damage.
Lighting
Favia corals thrive under low to moderate lighting conditions, between 50 to 100 PAR. High-intensity lighting can stress the corals and lead to bleaching. It is advisable to monitor their reaction to light and adjust accordingly to maintain optimal health.
Water Flow
Maintaining a balance in water flow is essential for Favia corals. While they tolerate a broad range of flow patterns, excessive flow can damage the coral, while insufficient flow can create dead spots with detritus accumulation. Providing a medium-to-low water flow is recommended to promote a healthy environment for these corals.
Feeding
Favia corals primarily rely on their zooxanthellae for nutrition but also benefit from direct feeding. Offering a variety of frozen fish foods rich in vitamins and unsaturated fatty acids, such as shrimp, fish, and squid, in small sizes is ideal. Shutting off the flow for a brief period during feeding sessions allows the colony to capture and consume the food effectively.
Propagation
Propagation of Favia corals varies among different genera within the Favia category. While they can be easily cut and heal well, the growth rates differ significantly. Some varieties, like Favites, propagate rapidly, while others, like Coelastrea, are slower. Long-term commercial aquaculture success depends on understanding each genus's growth rate and suitability for propagation.
Localization & Habitat
Favia corals are primarily found in the Indo-Pacific region, including locations like Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. These corals thrive in tropical marine environments with stable water conditions, providing a vibrant addition to the reef ecosystem.
