Common name: Stone-leaf coral

General information

Lithophyllon undulatum, commonly known as Ruffled Ridge Coral, is a species of small polyp stony (SPS) coral. It is appreciated for its unique appearance, characterized by its undulating ridges and vibrant coloration, which can range from deep reds to greens and purples. This coral is a part of the family Fungiidae, which includes free-living corals that are often solitary in nature.

Care

Ruffled Ridge Coral requires moderate to high lighting conditions to thrive in a reef aquarium. It benefits from strong water flow, which helps to keep its surface free of detritus and provides the necessary nutrients. Care should be taken to place it in an area of the tank where it will not be shaded by other corals or structures. It is important to maintain stable water parameters, particularly calcium and alkalinity levels, to support its skeletal growth.

Symbiosis

Like many corals, Lithophyllon undulatum hosts zooxanthellae, symbiotic algae that live within its tissues. These algae provide the coral with essential nutrients through photosynthesis, while the coral provides protection and access to light. This symbiotic relationship is crucial for the coral's survival and is a key aspect of coral reef ecosystems.

Habitat

Lithophyllon undulatum is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with strong water movement and ample lighting, which are conducive to the growth of its symbiotic algae. In the wild, it can be found at varying depths, often on reef slopes or in lagoons.
