Common name: Leaf coral

General information

Pavona decussata, 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. This coral is part of the family Agariciidae and is known for its hardiness and adaptability in reef aquariums.

The species exhibits a range of colors from green to brown, and under intense lighting and optimal water conditions, it can develop bright, fluorescent tips. Pavona decussata grows in a plating and encrusting manner, which can add a dramatic three-dimensional aspect to the reef aquascape.

Care

Pavona decussata is considered a good choice for reef keepers who are new to keeping SPS corals. It is less demanding than some other SPS corals and can tolerate a range of lighting conditions, from moderate to high intensity. However, it thrives best under high-intensity lighting with a spectrum that promotes photosynthesis.

Stable water parameters are crucial for the health of this coral, with particular attention to calcium, alkalinity, and magnesium levels, which support its skeletal growth. Moderate to strong water flow is also beneficial, as it aids in the delivery of nutrients and removal of waste products.

Symbiosis

While Pavona decussata does not have any specific symbiotic relationships that are unique or particularly noteworthy in the context of home aquariums, it does host zooxanthellae, symbiotic algae that live within its tissues. These algae provide the coral with the majority of its nutritional needs through photosynthesis.

Habitat

Pavona decussata 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 where it can receive ample sunlight for its symbiotic zooxanthellae to perform photosynthesis effectively.
