Common name: Blue Staghorn Coral

General information

The Blue Staghorn Coral, Acropora tortuosa, is a small polyp stony (SPS) coral known for its intricate, twisted branches and vibrant blue coloration. It is a highly sought-after species in the reefkeeping hobby for its unique structure and beauty. This coral is part of the Acroporidae family, which is well-known for its contribution to reef-building in the wild.

Care

Acropora tortuosa requires stable water conditions and intense lighting to thrive in captivity. It is a fast-growing species that benefits from strong water flow to deliver nutrients and remove waste. Calcium, alkalinity, and magnesium levels should be maintained within optimal ranges to support its skeletal growth. Due to its sensitivity, it is recommended for experienced aquarists who can provide a consistent and well-maintained environment.

Symbiosis

Like many corals, Acropora tortuosa has a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. The coral provides the algae with a protected environment and compounds necessary for photosynthesis, while the algae produce oxygen and help the coral to remove waste. Additionally, they contribute to the coral's energy needs through the sugars they produce.

Habitat

In the wild, Acropora tortuosa is found in shallow reef environments where sunlight is abundant. It is commonly seen in the Indo-Pacific region, including the Great Barrier Reef. This species typically inhabits upper reef slopes and reef crests, where the water movement is strong, facilitating its growth and access to planktonic food.
