Common name: carnation coral

General information

The Smooth Star Coral, Caryophyllia inornata, is a solitary scleractinian coral that is often found in the aquarium trade due to its hardiness and unique appearance. Unlike many corals that form colonies, each Caryophyllia inornata is an individual polyp, which can make it a standout specimen in a reef tank. Its coloration varies from pale to deep green, often with a contrasting mouth color, which adds to its visual appeal.

Care

Smooth Star Coral is relatively easy to care for, making it suitable for both beginner and advanced reef keepers. It requires moderate lighting and water flow to thrive. Placement in the aquarium should be done with care to ensure that it receives adequate light without being damaged by excessive flow. It feeds on small particulate foods, such as plankton, and benefits from regular feedings of microplankton or finely minced seafood.

Symbiosis

While Caryophyllia inornata does not have the same type of symbiotic relationships as some corals that host fish or invertebrates, it does engage in a mutualistic relationship with zooxanthellae, photosynthetic algae that live within its tissues. These algae provide the coral with nutrients produced through photosynthesis, while the coral provides the algae with a protected environment and access to light.

Habitat

Smooth Star Coral is typically found in the cooler waters of the Atlantic Ocean, from the coasts of Europe to the Mediterranean Sea. It inhabits a range of depths, often found on rocky substrates or within crevices where it can extend its polyp to feed. In the aquarium, replicating these conditions by providing a stable environment with rockwork and crevices can help the coral to feel at home and flourish.
