Common name: Hump coral

General information

Porites cylindrica, commonly known as Cylindrical Porites, is a species of stony coral that forms large, robust colonies. It is characterized by its cylindrical branches, which can vary in color from pale brown to greenish or bluish hues. This coral is widespread in the Indo-Pacific region and is known for its resilience, making it a suitable candidate for reef aquariums.

Care

Cylindrical Porites is a hardy coral species that can thrive in a variety of lighting conditions, from moderate to high intensity. It benefits from moderate to strong water flow, which helps to keep the surface free of sediment and delivers nutrients. This coral is photosynthetic and hosts zooxanthellae, symbiotic algae that provide it with the majority of its nutritional needs through photosynthesis. Supplemental feeding is not necessary but can promote faster growth and more vibrant colors.

Symbiosis

While not known for hosting fish or invertebrates, Porites cylindrica does engage in a crucial symbiotic relationship with zooxanthellae. These microscopic algae live within the coral's tissues and are essential for the coral's survival, providing it with nutrients produced through photosynthesis.

Habitat

Porites cylindrica is found in a range of reef habitats, from shallow lagoons to deeper slopes, typically up to a depth of around 40 meters. It is a common sight in the reefs of the Indo-Pacific, from the Red Sea to the central Pacific Ocean. The species is adaptable and can be found in both high-energy reef fronts and more protected back reef environments.
