Common name: Leaf coral

General information

Pavona maldivensis, commonly known as Cactus Coral, Lettuce Coral, or Potato Chip Coral, is a species of small polyp stony (SPS) coral. It is appreciated for its unique growth form that resembles the undulating folds of lettuce or cactus pads, giving it a distinct appearance in the reef aquarium. This coral is part of the family Agariciidae and is known for its hardiness and adaptability to various lighting conditions in captivity.

Care

Cactus Coral is considered a good choice for intermediate to advanced reef aquarists due to its moderate care requirements. It thrives under moderate to high lighting and benefits from moderate water flow, which helps to remove detritus from its surface and provides essential nutrients. While it can obtain much of its nutrition from the symbiotic algae (zooxanthellae) living within its tissues, supplemental feeding with fine particulate foods can promote growth and coloration.

Symbiosis

Like many SPS corals, Pavona maldivensis hosts zooxanthellae, photosynthetic algae that provide the coral with nutrients through photosynthesis. In return, the coral provides the algae with a protected environment and the compounds necessary for photosynthesis. This symbiotic relationship is crucial for the health and growth of the coral.

Habitat

Pavona maldivensis is found in the warm waters of the Indian and Pacific Oceans, including the Maldives, from which its species name is derived. It typically grows in shallow reef environments where it forms extensive colonies. In the wild, these corals can be found at various depths, often in areas with strong water movement that supports their growth and development.
