| 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 exhibit a visually diverse array of brain coral growth forms, showcasing a multitude of colors and patterns, though the term "Favia" now predominantly refers to two Caribbean species, Favia fragum and Favia gravida. The former extensive classification of Favia species has reduced due to reclassification into genera like Dipsastraea, Goniastrea, Coelastrea, or Favites.
Demands and Hardiness (Setup)
Favia corals typically require low to moderate lighting conditions, preferring intensities between 50 to 100 PAR to prevent bleaching. These corals can survive well in dim lighting but are intolerant of excessively bright conditions. Water flow for Favia is best maintained at a low to moderate level to avoid detritus settling on colonies or causing physical damage. Adjusting flow specifically for Favia may not be crucial; a middle-of-the-road flow is generally suitable.
Lighting
Ideal lighting conditions for Favia corals range from low to moderate levels, typically between 50 to 100 PAR. Higher lighting intensities can lead to bleaching and should be approached cautiously, with corals potentially needing relocation to shadier areas of the tank if signs of stress appear.
Water Flow
Maintaining a low to moderate water flow is recommended for Favia corals. While water flow is crucial for coral health, it is less critical for Favia compared to other corals. Balancing flow to prevent detritus accumulation or physical damage to the coral is essential. Adjusting flow during feeding sessions can help corals consume food effectively.
Feeding
Favia corals rely significantly on their zooxanthellae, but direct feeding can be beneficial. Feeding a variety of small-sized frozen fish foods containing vitamin additives and highly unsaturated fatty acids is recommended. Ensuring that food particles are small enough for the coral polyps to ingest fully is essential, as some species like Favites have smaller mouths.
Propagation
Propagating Favia corals can vary among different genera within the Favia group. While corals like Favites exhibit rapid growth, others like Coelastrea grow more slowly, posing challenges for long-term aquaculture. Despite variations in growth rates, Favia corals generally respond well to cutting and healing post-propagation efforts.
Localization & Habitat
Favia corals are primarily found in the Indo-Pacific region, including islands like Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. The natural habitat of Favia encompasses diverse marine environments, contributing to the species' resilience and adaptability.
