Common name: Staghorn Coral

General information

Acropora caroliniana, commonly known as Staghorn Coral, is a species of small polyp stony (SPS) coral renowned for its branching growth form resembling the antlers of a stag. This coral is highly appreciated in the reefkeeping hobby for its intricate structure and vibrant colors, which can range from pale cream to deep green, depending on the lighting and water conditions.

Care

Staghorn Coral requires stable water conditions with strong lighting and moderate to high water flow to thrive. It is a fast-growing species that can benefit from the addition of calcium, alkalinity, and magnesium supplements to support its skeletal development. Careful placement is crucial to prevent damage to its delicate branches and to allow for ample growth space.

Symbiosis

Like many corals, Acropora caroliniana hosts symbiotic zooxanthellae algae within its tissues. These algae provide the coral with essential nutrients through photosynthesis, while the coral offers protection and access to light. This symbiotic relationship is vital for the coral's survival and growth.

Habitat

Acropora caroliniana is found in shallow reef environments typically at depths of 5 to 30 meters. It prefers clear, sunlit waters where it forms extensive colonies that contribute to the complex structure of coral reefs. These habitats are crucial for marine biodiversity, offering shelter and resources to a multitude of reef organisms.
