Common name: Banana coral

General information

Trachyphyllia geoffroyi, commonly known as Open Brain Coral, is a large polyp stony (LPS) coral that is popular among reef aquarium enthusiasts for its vibrant colors and unique, fleshy appearance. It is often found in shades of red, green, blue, and pink, with fluorescent hues that can be quite striking under actinic lighting. This species is solitary, with a single large polyp extending from a skeletal base.

Care

Open Brain Coral is considered moderate in terms of care. It requires stable water conditions, moderate lighting, and low to moderate water flow within the aquarium. Placement is crucial; it should be placed on the sand bed or on a lower rock where it is less likely to be damaged by other corals or fish. Feeding is beneficial, and it can be target-fed with meaty foods like mysis shrimp or finely chopped seafood.

Symbiosis

While not known for hosting fish, Trachyphyllia geoffroyi can have a mutualistic relationship with small benthic organisms, such as certain species of crabs and shrimp, which may reside within its structure for protection.

Habitat

In the wild, Trachyphyllia geoffroyi is typically found in shallow reef environments, often in protected lagoons or on reef slopes. It prefers areas with soft substrates where it can nestle into the sand to support its fleshy polyp.
