Common name: Sinuous cup coral

General information

Symphyllia Brain Coral, also known as Open Brain Coral or Dented Brain Coral, is a large polyp stony (LPS) coral that is popular among reef aquarium hobbyists for its vibrant colors and intriguing patterns. Symphyllia agaricia is often confused with other brain corals, particularly those in the genus Lobophyllia, due to their similar appearance. However, Symphyllia corals have a distinctive meandering, maze-like groove pattern on their surface.

Care

Caring for Symphyllia Brain Coral requires moderate to high lighting and medium water flow within the aquarium to mimic their natural reef environment. They are photosynthetic and host zooxanthellae, symbiotic algae that provide them with nutrients through photosynthesis. Supplemental feeding with meaty foods like mysis shrimp can promote growth and maintain their vibrant coloration.

Symbiosis

While Symphyllia Brain Coral does not have any specific symbiotic relationships akin to clownfish and anemones, they do benefit from the presence of cleaner shrimp and certain fish that help keep their surfaces free from debris and parasites.

Habitat

Symphyllia Brain Coral is found on reef slopes and in lagoons, typically at depths where light is sufficient for photosynthesis. They are distributed across the Indo-Pacific region, including the Great Barrier Reef, the Red Sea, and the central Pacific.
