Pectinia is a unique and striking LPS (Large Polyp Stony) coral, often referred to as Lettuce Coral or Space Coral due to its ruffled, sculptural appearance. It forms dramatic, leaf-like structures with sharp ridges and vibrant colorations, ranging from green and purple to multicolored fluorescents under actinic lighting. This coral is a true showpiece for any reef aquarium, especially under blue lights where its colors really stand out. However, it does have long sweeper tentacles and can be aggressive toward nearby corals.
