Common name: domed star coral

General information

The Pillar Coral, Dichocoenia stokesi, is a hard coral species known for its unique, vertically oriented columns or pillars that can reach impressive heights. This coral is part of the family Meandrinidae and is native to the western Atlantic Ocean, including the Caribbean Sea and the Gulf of Mexico. Its distinct growth form not only adds structural complexity to the reef but also provides habitat for a variety of marine life.

Care

Pillar Coral is considered a moderate care level species in the aquarium hobby. It requires stable water conditions with moderate to high lighting and water flow to thrive. It is important to maintain calcium, alkalinity, and magnesium levels within the appropriate ranges to support its skeletal growth. This coral may benefit from supplemental feedings of microplankton or other coral foods designed to mimic its natural diet.

Symbiosis

While Dichocoenia stokesi does not have the same level of symbiosis as some other corals, its structure provides a refuge and hunting grounds for small reef fish and invertebrates. Its pillars can also serve as attachment points for various sponges and bivalves, creating a diverse microhabitat.

Habitat

Pillar Coral is typically found in shallow reef environments, often in areas with clear water and moderate to strong currents. It can be found at depths ranging from just below the surface to about 20 meters. This species is sensitive to environmental changes and is currently listed as vulnerable due to threats like coral bleaching, disease, and ocean acidification.
