Common name: Leaf coral

General information

Pavona frondifera, commonly known as Cactus Coral or Leaf Coral, is a species of small polyp stony (SPS) coral. It is appreciated for its unique leaf-like appearance and its ability to add texture and diversity to a reef aquarium. This coral exhibits a range of colors, typically green or brown, with lighter tips on its fronds that can enhance the visual appeal of any reef setup.

Care

Cactus Coral is moderately challenging to keep, requiring stable water conditions and moderate to high lighting to thrive. It benefits from moderate to strong water flow, which helps to keep the fronds free of detritus and provides the coral with essential nutrients. Calcium, alkalinity, and magnesium levels should be maintained to support skeletal growth. Target feeding is not necessary, but the coral can benefit from the occasional feeding of microplankton or other coral foods.

Symbiosis

While Pavona frondifera does not have any specific symbiotic relationships that are notable in the context of home aquariums, it does engage in the classic coral symbiosis with zooxanthellae, photosynthetic algae that live within its tissues. This mutualistic relationship allows the coral to receive nutrients from the algae's photosynthesis, while the algae benefit from a protected environment and access to the coral's waste products.

Habitat

Cactus Coral is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with strong light and water movement, which are conditions that should be replicated in the home aquarium for optimal health. In the wild, Pavona frondifera can be found at various depths, often forming extensive colonies that contribute to the structure of the reef.
