Favia corals are large polyp stony (LPS) corals. They have an encrusting base but usually grow forming a dome-shape. Favia corals are also known as "brain corals" or "closed brain corals." The corallites of the Favia coral form their own individual walls. You should be able to see the groove in-between the 2 individual walls of a Favia coral. Sometimes this can make it hard to distinguish between a Favia coral and a Favites coral. (They look and are very similar, but Favites corals will have one fused/shared wall instead of the two distinct walls.) We allow some grace in the identification of these corals as it can be very hard to determine in smaller specimens. They both require similar care, so it's okay if you aren't 100% which type you have right away. Favia corals appear in a variety of colors and patterns.
Caring for Favia corals is relatively easy, making them an excellent choice for both beginner and expert Reef Chasers. They require low to moderate lighting combined with moderate water movement. We recommend 100-200 PAR. Bear in mind that many corals can be gradually acclimated to lighting beyond their normal range. Water flow that is too high can damage their fleshy polyps.
Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. Favia corals benefit from targeted feeding of meaty foods like Mysis shrimp or brine shrimp. To maintain good health, calcium, strontium, and other trace elements should be monitored and added as needed.
When placing your Favia coral, please remember that Favia corals are known to be aggressive. They have long sweeper tentacles that can extend to sting other corals that get too close. Be sure to provide enough personal space for your Favia coral to grow and thrive.
