Care

Agassiz's Coral is considered a good choice for intermediate to advanced reef keepers due to its moderate care requirements. It thrives in stable aquarium conditions with moderate to high lighting and water flow. It is important to maintain consistent levels of calcium, alkalinity, and magnesium to support its skeletal growth. Feeding is not essential but can promote faster growth and more vibrant colors; target feeding with microplankton or coral foods is beneficial.

Symbiosis

While Cyphastrea agassizi does not have any specific symbiotic relationships that are crucial for its survival, it can contribute to the overall biodiversity and health of the reef aquarium by providing shelter and territory for small invertebrates and microfauna.

Habitat

In the wild, Cyphastrea agassizi is found on reef slopes and in lagoons, typically in areas with moderate water movement. It is distributed across the Indo-Pacific region, including the Red Sea, East Africa, and the central Pacific.
