Common name: Porites cylindrica

General information

Porites cylindrica, commonly known as the cylindrical finger coral, is a species of stony coral that is widely appreciated in the reefkeeping hobby for its hardiness and unique growth form. This coral is characterized by its cylindrical branches that can form dense mats or more open, tree-like structures. The coloration of P. cylindrica varies from pale cream to deep brown, often with green or yellow hues, depending on the lighting and water conditions.

Care

Cylindrical finger coral is considered a good choice for both novice and experienced reefkeepers due to its adaptability and resilience. It thrives in moderate to high lighting conditions and benefits from moderate water flow, which helps to keep the branches free of detritus and provides essential nutrients. Regular feeding with fine particulate foods can promote growth and maintain health, but P. cylindrica is also capable of obtaining nutrients through its symbiotic relationship with zooxanthellae.

Symbiosis

Like many stony corals, Porites cylindrica hosts symbiotic zooxanthellae within its tissues. These photosynthetic algae provide the coral with the majority of its nutritional needs through the process of photosynthesis. In return, the coral provides a protected environment and the compounds necessary for photosynthesis.

Habitat

Porites cylindrica is found in a variety of reef environments, from shallow lagoons to deeper reef slopes. It is a versatile species that can adapt to different levels of light and water movement, making it a common sight in many Indo-Pacific coral reefs. In the wild, it can be found at depths ranging from just below the surface to over 40 meters deep.
