Care
Acropora granulosa requires stable water conditions and intense lighting to thrive in captivity. It is a high-light species that also demands strong water movement to mimic its natural reef environment. Proper calcium, alkalinity, and magnesium levels are crucial for its growth. Due to its sensitivity, it is recommended for experienced reef keepers who can maintain consistent water parameters.
Symbiosis
Like many Acropora species, A. granulosa may host a variety of reef-dwelling creatures, including small crustaceans and fish that seek refuge within its branches. These symbiotic relationships can benefit the coral by improving water circulation around its structure and reducing algae growth.
Habitat
Acropora granulosa is found in the Indo-Pacific region, typically in shallow reef environments where it is exposed to strong light and water flow. It is often seen at depths ranging from just below the surface to about 20 meters, where it forms part of the complex reef ecosystem.
