Common name: Staghorn Coral

General information

Acropora spicifera, 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 deep greens to purples and blues. Acropora spicifera is a fast-growing species that can form extensive colonies in the wild, contributing significantly to reef building and providing habitat for a myriad of marine life.

Care

Staghorn Coral requires stable water conditions with strong lighting and significant water flow to thrive in captivity. It is essential to maintain high water quality with low nutrient levels to prevent algae overgrowth and promote healthy coral tissue. Calcium, alkalinity, and magnesium levels should be monitored and maintained to support the coral's skeletal growth. Acropora spicifera is sensitive to changes in its environment, so gradual acclimation and consistent parameters are crucial.

Symbiosis

Acropora spicifera, like many corals, has a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. This symbiosis is vital for the coral's survival as the zooxanthellae provide the majority of the coral's nutritional needs through photosynthesis. In return, the coral provides the algae with a protected environment and the compounds necessary for photosynthesis.

Habitat

Acropora spicifera is found in the shallow waters of the Indo-Pacific region, including the Red Sea, Indian Ocean, and central and western Pacific Ocean. It typically inhabits reef slopes and lagoons where it can be exposed to strong water movement and high light levels, which are essential for its growth and development.
