Common name: pillar coral

General information

The Pillar Coral, Dendrogyra cylindrus, is a hard coral species known for its unique, vertically oriented columns that can grow up to several meters in height. This coral is easily recognizable due to its large, cylindrical branches that resemble pillars, hence its common name. The polyps of Pillar Coral are usually extended during the day, giving the coral a fuzzy appearance, which is atypical as most hard corals retract their polyps during daylight hours.

Care

Pillar Coral requires moderate to high lighting conditions and moderate water flow within the aquarium to thrive. It is important to maintain stable water parameters, particularly calcium and alkalinity levels, to support its skeletal growth. This species is less aggressive than many other corals, so it can be placed near other non-aggressive corals with adequate space for growth.

Symbiosis

Pillar Coral does not have the same type of symbiotic relationships with fish or invertebrates as some other corals do. However, it does host symbiotic zooxanthellae within its tissues, which provide the coral with nutrients through photosynthesis.

Habitat

Naturally found in the Caribbean Sea and the western Atlantic Ocean, Pillar Coral typically inhabits shallow reef environments. It prefers areas with clear water and is often found at depths ranging from 1 to 20 meters. Due to its structure, it provides habitat and shelter for a variety of reef organisms.
