Pavona (Pavona sp.)are a genus of small polyp stony Corals that are native to the Red Sea, and the Indian and Pacific Oceans. They are sometimes called Cactus Corals as they resemble Cactuses but they are also called Lettuce Coral, and Potato Chip Coral. One unique thing about this SPS coral is that it has polyps on both the top and bottom sides of its branches or arms. When placing them in the tank,make sure to situate them in an area with moderate to high light and flow. Additionally, they are known to be an aggressive coral, so give them space as they tend to grow quickly once established in a system. They are nourished by zooxanthallae, but they can be supplemented with phytoplankton, zooplankton, as well as by coral foods available on the market. Although they are a hardy coral, they still need to be dipped and slowly acclimated to any reef tank to maximize their chance of success.
