Common name: Leaf coral

General information

Pavona varians, 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 leaves of lettuce or the ridges of a cactus. This coral exhibits a variety of colors, often displaying beautiful shades of green, brown, or pink, with the polyps typically contrasting in color.

Care

Cactus Coral is considered a good choice for intermediate to advanced reef aquarists. It requires stable water conditions, moderate to high lighting, and medium to strong water flow to thrive. Pavona varians is a photosynthetic coral, relying heavily on the symbiotic algae, zooxanthellae, living within its tissue for nutrition. However, supplemental feeding with fine particulate foods can promote growth and health.

Symbiosis

While Pavona varians does not have any specific symbiotic relationships akin to clownfish and anemones, it does rely on the symbiotic zooxanthellae for its nutritional needs. This mutualistic relationship is crucial for the coral's survival, especially in nutrient-poor environments typical of coral reefs.

Habitat

Pavona varians is found in the Indo-Pacific region, typically in shallow reef environments. It can be found at various depths, often forming large, plate-like structures that provide habitat and shelter for a variety of reef organisms.
