Common name: Blue coral

General information

The Blue Ridge Coral, Heliopora coerulea, is a distinctive species of octocoral known for its unique blue skeleton, which is due to the presence of a copper-based pigment called linarite. Unlike most corals, it belongs to the order Helioporacea and is the only extant species in its family, Helioporidae. This coral is not only admired for its aesthetic appeal but also for its contribution to reef building.

Care

Blue Ridge Coral is considered a hardy species suitable for intermediate to advanced reef keepers. It thrives in moderate to high lighting conditions and requires moderate water flow to prevent sediment accumulation and promote nutrient uptake. While it can obtain nutrients through photosynthesis via its symbiotic algae, supplemental feeding with planktonic foods can benefit its growth and health.

Symbiosis

Heliopora coerulea forms a mutualistic relationship with photosynthetic algae known as zooxanthellae, which live within its tissues. The algae provide the coral with organic compounds produced through photosynthesis, while the coral offers the algae protection and access to sunlight.

Habitat

This species is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. It typically inhabits shallow waters, often forming extensive colonies in lagoons and on reef flats. The Blue Ridge Coral can be found at depths ranging from just below the surface to about 30 meters, where it contributes to the complex structure of coral reefs.
