Common name: Leaf coral

General information

Pavona duerdeni, 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, which can add a distinct texture and movement to the reef aquarium landscape. This coral is part of the family Agariciidae and is found in various shades of green, brown, and sometimes with hints of pink or purple.

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 conditions and benefits from moderate water flow, which helps to keep its surface free of detritus and provides the necessary nutrients. Stable water parameters are crucial for the health of SPS corals, and calcium, alkalinity, and magnesium levels should be maintained to support skeletal growth. Targeted feeding is not typically necessary, as Pavona duerdeni can derive nutrition from photosynthesis performed by its symbiotic zooxanthellae, but occasional feeding with microplankton can promote growth and vitality.

Habitat

Pavona duerdeni is found in the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the central and western Pacific Ocean. It typically inhabits shallow reef environments and lagoons, often in areas with strong light and water movement. In the wild, it can be found at varying depths, usually between 5 to 25 meters, forming either encrusting or plating colonies that contribute to the complex structure of coral reefs.
