Common name: Staghorn Coral

General information

Acropora grandis, commonly known as Staghorn Coral, is a species of small polyp stony (SPS) coral renowned for its robust branches and vibrant colors, ranging from deep purples to greens. This coral is a significant contributor to reef building in the wild, providing complex habitats for a myriad of marine life.

Care

Staghorn Coral requires strong lighting and turbulent water flow to thrive in captivity. It is essential to maintain stable water parameters, particularly calcium and alkalinity levels, to support its rapid skeletal growth. Acropora grandis is also sensitive to changes in water quality, so regular water testing and maintenance are crucial.

Symbiosis

Acropora grandis does not have any specific symbiotic relationships that are of particular interest to the aquarium hobby, but like many corals, it houses symbiotic algae known as zooxanthellae within its tissues. These algae provide the coral with nutrients through photosynthesis, which is why intense lighting is vital for the coral's health.

Habitat

This species is found in the shallow waters of the Indo-Pacific region, typically in reef slopes and lagoons where the water movement is strong. It is often seen at depths ranging from just below the surface to about 20 meters, where it forms dense thickets that are crucial for the structural integrity of the reef ecosystem.
