Common name: Leaf coral

General information

Pavona clavus, commonly known as Cactus Coral or Potato Chip Coral, is a species of small polyp stony (SPS) coral. It is appreciated for its unique growth form, which resembles the undulating ridges of a cactus, and its ability to add texture and diversity to a reef aquarium. This coral exhibits a variety of colors, ranging from green to brown, and under the right conditions, it can display vibrant fluorescent highlights.

Care

Cactus Coral is moderately challenging to keep, requiring stable water conditions and intense lighting to thrive. It benefits from moderate to strong water flow, which helps to keep the coral clean and deliver nutrients. Calcium, alkalinity, and magnesium levels should be maintained within the appropriate ranges for SPS corals to support skeletal growth. Feeding is not essential, but the coral can benefit from occasional target feeding with microplankton or other coral foods designed for SPS.

Symbiosis

Pavona clavus does not have any specific symbiotic relationships that are notable in the context of home aquariums. However, like many corals, it houses symbiotic algae known as zooxanthellae within its tissues, which provide the coral with nutrients through photosynthesis.

Habitat

This species is found in the Indo-Pacific region, typically in shallow reef environments where it receives plenty of sunlight. It can be found at various depths, often forming extensive colonies that contribute to the complex structure of coral reefs.
