Common name: Corymbose branching plate coral

General information

Acropora cerealis, commonly known as Staghorn Coral, is a small polyp stony (SPS) coral that is widely appreciated in the reefkeeping hobby for its intricate branching structure and vibrant colors. This species is part of the Acroporidae family, which is known for its fast growth rates and contribution to reef building. Staghorn Corals come in a variety of colors, including shades of brown, green, purple, and blue, often with contrasting tips.

Care

Staghorn Coral requires stable water conditions and intense lighting to thrive in a home aquarium. They benefit from strong water flow to mimic their natural reef habitat, which helps to keep their branches free of detritus and supplies them with necessary nutrients. Calcium, alkalinity, and magnesium levels should be maintained within optimal ranges to support their skeletal growth. Targeted feeding is not typically necessary, as they receive most of their nutrition from photosynthetic algae, known as zooxanthellae, living within their tissues.

Symbiosis

Acropora cerealis, like many corals, has a symbiotic relationship with zooxanthellae. These microscopic algae reside within the coral's tissues and provide it with the majority of its nutritional needs through photosynthesis. In return, the coral provides the algae with a protected environment and the compounds necessary for photosynthesis.

Habitat

Staghorn Coral is found in shallow reef environments, typically in the Indo-Pacific region. They prefer clear, sunlit waters where they can form dense thickets, providing habitat and shelter for a myriad of marine life. In the wild, they can be found at depths ranging from just below the surface to about 30 meters deep.
