| 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, exhibiting multiple growth forms and a wide range of colors and patterns. Originally comprising nearly 100 species, the majority have been reclassified into genera such as Dipsastraea, Goniastrea, Coelastrea, or Favites, leaving only two species recognized today: Favia fragum and Favia gravida, both native to the Caribbean region. These corals are large polyp stony corals that have become scarce in the reef aquarium hobby due to legal restrictions on collecting Caribbean species.
Demands and Hardiness
Favia corals require low to moderate lighting conditions, ideally ranging from 50 to 100 PAR to thrive successfully. While they can tolerate variations in water flow, a middle-of-the-road low to medium flow is recommended to prevent detritus buildup or damage to the coral. Feeding these corals directly can be beneficial, with recommended food sizes falling within the range of 0.1mm to 13mm. They can be fed a mix of seafood with vitamin additives and highly unsaturated fatty acids to supplement their nutrition.
Lighting
Favia corals prefer low to moderate lighting levels around 50 to 100 PAR. Higher intensity lighting can lead to stress and potential bleaching, prompting the need for relocation to shadier areas if necessary. Dim lighting is generally well-tolerated, but excessively bright conditions should be avoided to prevent coral harm.
Water Flow
Optimal water flow for Favia corals is considered to be low to moderate. Maintaining a consistent and gentle flow helps prevent detritus accumulation while avoiding potential damage to the coral. Temporary cessation of water flow for 20-30 minutes during feeding sessions can aid in efficient food consumption by the colony.
Feeding
Favia corals primarily rely on their zooxanthellae for nutrients but benefit from direct feeding. Suitable food items include zooplankton, Mysis, and various powdered or pellet foods in small sizes. Offering a diverse diet of meaty foods like shrimp, fish, and squid enriched with vitamins and HUFA can enhance their health and vibrancy.
Propagation
Propagation of Favia corals varies across different genera, with some species growing rapidly while others exhibit slower growth rates. Despite being easily cut and capable of healing well, long-term aquaculture success is hindered by differing growth rates among the coral varieties. While most Favia corals can be propagated successfully, certain species may not be ideal candidates for commercial aquaculture ventures.
Localization & Habitat
Favia corals can be found in the islands of the Indo-Pacific region, including locations such as Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. Known for their striking visual appearance and diverse coloration, these corals contribute to the underwater ecosystems of their natural habitats.
