Common name: Column Staghorn Coral

General information

Acropora palifera, commonly known as the Smooth cactus coral, is a species of small polyp stony (SPS) coral that is popular among reef aquarium hobbyists for its robustness and attractive growth forms. This species is part of the Acroporidae family, which is known for its fast growth rates and contribution to reef-building. Acropora palifera exhibits a variety of growth forms, from table-like structures to branching forms, and can display a range of colors from pale green to brown, often with lighter tips.

Care

Acropora palifera requires stable water conditions and intense lighting to thrive in captivity. It is recommended to maintain strong water flow to mimic its natural reef environment, which helps in nutrient transport and removal of waste products. This coral benefits from the addition of calcium, alkalinity, and magnesium supplements to support its skeletal growth. It is also important to keep phosphate and nitrate levels low to prevent algae growth and maintain vibrant coloration.

Symbiosis

Like many corals, Acropora palifera forms a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. The zooxanthellae provide the coral with nutrients produced through photosynthesis, while the coral provides the algae with a protected environment and access to sunlight. This relationship is crucial for the coral's survival and growth.

Habitat

Acropora palifera is found in shallow reef environments, typically in the Indo-Pacific region. It prefers well-lit areas with moderate to strong water movement. In the wild, this species can be found at various depths, often forming extensive colonies that contribute to the complex structure of coral reefs.
