Common name: Wrinkle coral

General information

Coscinaraea crassa, commonly known as Boulder Brain Coral, is a species of stony coral that exhibits a massive growth form. It is characterized by its thick, fleshy polyps and a highly convoluted surface resembling a brain, hence the name. This coral is known for its resilience and ability to withstand various environmental conditions, making it a suitable candidate for reef aquariums.

Care

Boulder Brain Coral requires moderate to high lighting conditions to thrive in captivity. It benefits from moderate water flow, which helps to keep the surface free of sediment and delivers nutrients to its polyps. This coral is photosynthetic and hosts zooxanthellae, symbiotic algae that provide it with the majority of its nutritional needs through photosynthesis. Supplemental feeding with microplankton or coral foods can promote growth and vitality.

Symbiosis

While not known for hosting fish or invertebrates, Boulder Brain Coral may engage in mutualistic relationships with certain types of algae and bacteria that enhance its nutrient uptake and contribute to the overall health of the coral reef ecosystem.

Habitat

Coscinaraea crassa is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with strong light and some water movement, which are conditions that support the growth of its symbiotic algae. In the wild, it can be found at varying depths, often forming large, dome-shaped structures that contribute to the complexity and diversity of the reef.
