| 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 brain corals, with their visually diverse growth forms and vibrant colors, were once a significant category in the reef aquarium hobby. However, due to reclassification by coral taxonomists over the years, most of the corals previously classified as Favia now belong to genera like Dipsastraea, Goniastrea, Coelastrea, or Favites. Currently, only two species, Favia fragum and Favia gravida, both Caribbean species, remain in the hobby.
Demands and Hardiness
Pyromaniac Favia, a member of the Favia & Favites family, requires low to moderate lighting, with an optimal range between 50 to 100 PAR. These corals are sensitive to high lighting and may risk bleaching if exposed to excessive light. Water flow should be maintained at a low to moderate level, as Favia are generally tolerant of various flow patterns. Providing a middle-of-the-road flow is recommended to avoid settling detritus or damaging the coral.
Lighting
Favia corals thrive best under low to moderate lighting conditions, typically ranging from 50 to 100 PAR. It is essential to avoid exposing them to intense light, as they may be at risk of bleaching. If experimenting with higher light levels, closely monitor the coral's response and be prepared to relocate it to a shadier area if needed.
Water Flow
Maintaining a low to moderate water flow is crucial for the health of Favia corals. While water flow is less critical for Favia compared to other corals, providing a moderate flow helps prevent debris accumulation and coral damage. Adjusting flow specifically for Favia may not be necessary, as they are generally tolerant of various flow patterns.
Feeding
Favia corals primarily rely on their zooxanthellae for nutrients but can also benefit from direct feeding. Offering a mixture of small meaty foods such as shrimp, fish, and squid with vitamin additives and HUFA can enhance their health. Feeding sessions should involve shutting off the flow for 20-30 minutes to allow the coral to consume the food effectively.
Propagation
Propagation of Favia corals varies depending on the genus. While some varieties like Favites exhibit rapid growth and can be easily cut and healed, others, such as Coelastrea, have slower growth rates. Though Favia corals generally heal well from cutting, their growth rates pose a challenge for long-term commercial aquaculture.
Localization & Habitat
Favia corals are typically found in the Indo-Pacific islands, including regions like Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. Their natural habitat consists of diverse reef environments where they contribute to the coral ecosystem's biodiversity and structure.
