Closed Brain Green "Symphyllia" Closed Brain SUPER Green "Symphyllia"

The Closed Brain Green 'Symphyllia' (Symphyllia agaricia) is a remarkable coral species native to the warm waters of the Coral Triangle, particularly around Bali, Indonesia. This coral is renowned for its intricate, maze-like patterns and vivid green coloration, which can range from bright lime to deep emerald shades. Its unique structure resembles a brain, with distinct valleys and ridges that not only add to its aesthetic appeal but also play a vital role in its feeding and defense mechanisms.

In terms of natural history, Symphyllia agaricia is often found in shallow reef environments, thriving in areas with moderate water movement and ample light. This species is a hermatypic coral, meaning it relies on symbiotic zooxanthellae algae for energy through photosynthesis, while also capturing plankton and organic matter from the water column. The closed brain coral exhibits a fascinating behavior of retracting its polyps into its skeleton during the night or when stressed, offering protection from predators.

The habitat of the Closed Brain Green 'Symphyllia' is typically characterized by rocky substrates, where it can anchor securely and benefit from the nutrient-rich waters. It coexists with various reef fish and invertebrates, contributing to the biodiversity of its ecosystem. As a slow-growing species, it can take years to reach its full potential size, making it a long-term addition to any aquarium.

In aquaristic settings, this coral not only serves as a focal point due to its vibrant colors but also plays an essential role in maintaining water quality and providing habitat for small marine organisms, making it a favorite among reef enthusiasts and aquarium collectors alike.

To successfully care for Closed Brain Green 'Symphyllia', it is essential to maintain stable water parameters. Ideal temperature ranges from 24°C to 28°C, with a salinity between 1.020 and 1.025 ppt. The pH should be kept between 8.1 and 8.4 to ensure optimal health. This coral thrives in well-lit environments, so providing adequate lighting—preferably with a combination of LED and fluorescent lights—is crucial.

Feeding should consist of a mix of high-quality coral foods, including plankton and other small particulates, supplemented by the natural photosynthesis from its symbiotic algae. Compatibility with other tank inhabitants is generally good, but caution is advised with aggressive species that may harm the coral. During acclimation, it is vital to introduce this species slowly to avoid stress, ideally through a drip acclimation method over several hours.

Quarantine is recommended before introducing to the main display tank to prevent the introduction of pests or diseases. Monitoring for any signs of distress, such as bleaching or retraction of polyps, is essential to ensure the coral is adapting well to its new environment.

The Closed Brain Green 'Symphyllia' is a hardy coral suitable for shipping, provided that proper care is taken during transport. It should be packed securely to minimize movement and stress. Recommended packing density is 1-2 pieces per box, depending on their size. Temperature should be maintained between 22°C and 26°C during shipping to prevent thermal shock. This species is not listed under CITES, but compliance with local regulations is necessary.
