Common name: Sinuous cup coral

General information

Symphyllia Brain Coral, also known as Open Brain Coral, is a large polyp stony (LPS) coral that is popular among reef aquarium hobbyists for its vibrant colors and intriguing growth patterns. Symphyllia radians is often confused with other brain corals, particularly those in the genus Lobophyllia, due to their similar appearance. However, Symphyllia corals have a unique meandering valley structure that distinguishes them from their relatives.

Care

Symphyllia corals are moderately easy to care for, making them a good choice for intermediate aquarists. They require moderate to low water flow and moderate lighting to thrive. It's important to place them on the substrate or on a lower position in the reef tank to avoid excessive light exposure, which can cause bleaching. They benefit from supplemental feedings of meaty foods like mysis shrimp and finely chopped seafood.

Symbiosis

While Symphyllia corals do not have a specific symbiotic relationship like clownfish and anemones, they do host a variety of small marine organisms. These can include microfauna that find refuge within the coral's structure, contributing to a diverse and balanced reef ecosystem.

Habitat

Symphyllia Brain Coral is found in the Indo-Pacific region, typically in shallow reef environments. They are often located on reef slopes or in lagoons where they can expand their fleshy polyps to feed. The species is adaptable to various light and flow conditions found within these habitats.
