| 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 present a visually diverse array of brain coral forms, showcasing various colors and patterns. While once abundant, the number of Favia species in the reef aquarium hobby has significantly decreased, with only Favia fragum and Favia gravida being legal for collection.
Demands and Hardiness
Favia corals, such as the Lemon Lime Favia, require low to moderate lighting conditions, approximately 50 to 100 PAR, as higher lighting may lead to bleaching. They can thrive in varying water flow patterns, with a preference for low to medium flow levels. Feeding these corals with a mix of small zooplankton, Mysis, powdered, and pellet food is essential for their health.
Lighting
Optimal lighting for Favia corals is in the low to moderate range to prevent bleaching and ensure their well-being in a reef aquarium setup. It is crucial to monitor light intensity closely to avoid stressing the corals.
Water Flow
Favia corals are tolerant of different water flow patterns, but a balanced approach of low to medium flow is recommended to prevent detritus accumulation and coral damage. Adjusting flow during feeding sessions by briefly shutting it off allows the colony to consume food efficiently.
Feeding
Favia corals heavily rely on their zooxanthellae for nutrition but benefit from direct feeding as well. Offering a variety of frozen fish foods rich in vitamins and fatty acids, such as shrimp, fish, and squid, in small sizes suitable for easy ingestion by the polyps is ideal. Spot feeding while minimizing flow ensures the effective utilization of food.
Propagation
Propagation of Favia corals varies among different genera, with some species growing faster than others. While they can heal well from cutting, their growth rates pose challenges for long-term commercial aquaculture. Careful consideration of the specific coral variety is necessary for successful propagation efforts.
Localization & Habitat
Favia corals are native to the Indo-Pacific islands, including regions like Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. Their natural habitat features diverse marine ecosystems where they contribute to the reef's biodiversity and ecological balance.
