Common name: Acropora sarmentosa

General information

Acropora sarmentosa is a species of small polyp stony (SPS) coral known for its branching growth form and vibrant coloration, which can range from deep purples to greens. It is a popular choice among advanced reef aquarium hobbyists due to its striking appearance and dynamic structure. Like other Acropora species, A. sarmentosa contributes significantly to reef building in the wild, providing habitat for a myriad of marine organisms.

Care

A. sarmentosa requires stable water conditions and intense lighting to thrive in captivity. It prefers strong water flow to help deliver nutrients and remove waste products. Calcium, alkalinity, and magnesium levels should be maintained within optimal ranges for coral health. This species is more suited to experienced aquarists due to its sensitivity to changes in water quality and lighting.

Symbiosis

While not hosting large organisms like fish or invertebrates, A. sarmentosa, like other Acropora species, has a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. These algae provide the coral with essential nutrients through photosynthesis, while the coral provides protection and access to light.

Habitat

Acropora sarmentosa is found in the Indo-Pacific region, typically in shallow reef environments where sunlight is abundant. It is often seen in reef slopes and lagoons, where it forms part of the complex three-dimensional structure of coral reefs that support diverse marine life.
