Common name: Knob coral

General information

The Rose Coral, scientifically known as Favia rosaria, is a species of stony coral that is popular among reef aquarium enthusiasts. This coral is part of the family Faviidae and is known for its robustness and the beautiful rose-like pattern that its polyps create when fully extended. The coloration of Favia rosaria can vary, often displaying hues of green, brown, or pink, with the oral disc typically being a contrasting color which adds to its visual appeal in a reef tank setting.

Care

Favia rosaria is a hardy coral species that is well-suited for intermediate to experienced reef keepers. It thrives in moderate lighting conditions and benefits from moderate water flow, which helps to keep its surface free of debris and provides the necessary nutrients. This coral should be placed on the bottom to middle parts of the reef, where it can receive the appropriate amount of light without being damaged by excessive exposure. Feeding is not strictly necessary, as Favia rosaria hosts zooxanthellae that provide most of its nutritional needs through photosynthesis. However, supplemental feeding with microplankton or coral foods can promote faster growth and more vibrant colors.

Symbiosis

While Favia rosaria does not have the same level of symbiotic relationships as some other corals or marine species, it does engage in a mutualistic relationship with the zooxanthellae algae that reside within its tissues. These algae provide the coral with essential nutrients through photosynthesis, while the coral provides the algae with a protected environment and access to sunlight.

Habitat

Favia rosaria is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with stable conditions and is often found on reef slopes or in lagoons where it can grow in colonies that contribute to the complex structure of the reef ecosystem.
