Common name: Acropora microphthalma

General information

Acropora microphthalma is a species of small-polyped stony coral (SPS) that is popular among reef aquarium enthusiasts for its intricate branching structure and vibrant colors. This coral is part of the Acroporidae family, which is known for its fast growth rates and contribution to reef building in the wild. Acropora microphthalma, like other Acropora species, has a symbiotic relationship with zooxanthellae, which are photosynthetic algae that live within its tissues.

Care

Acropora microphthalma requires stable water conditions and intense lighting to thrive in captivity. It is important to maintain high water quality with low nutrient levels to prevent algae overgrowth and promote healthy coral coloration. Adequate water flow is also crucial to mimic its natural reef environment and to deliver nutrients to the coral. Calcium, alkalinity, and magnesium levels should be monitored and maintained to support skeletal growth.

Symbiosis

While Acropora microphthalma does not have specific symbiotic relationships like those seen with clownfish and anemones, its association with zooxanthellae is vital for its survival. The coral provides the algae with a protected environment and compounds necessary for photosynthesis, while the zooxanthellae supply the coral with oxygen and some of the organic compounds it produces.

Habitat

Acropora microphthalma is found in the Indo-Pacific region, typically in shallow reef environments where it is exposed to strong light and water movement. It is often seen in the back reef and fore reef zones, contributing to the complex structure of coral reefs in these areas.
