Common name: Least valley coral

General information

Leptoria phrygia, commonly known as Honeycomb Coral, is a species of stony coral that is popular among reef aquarium enthusiasts for its distinctive appearance. The coral's surface is characterized by a network of ridges and valleys that resemble a honeycomb pattern, giving it its common name. This species is part of the family Faviidae, which includes other large polyp stony corals that are well-known for their contributions to reef building.

Care

Honeycomb Coral requires moderate to high lighting conditions to thrive in a captive environment. It is photosynthetic and relies on the symbiotic algae, zooxanthellae, living within its tissues for nutrition. However, supplemental feeding with microplankton or finely minced seafood can promote growth and vitality. Stable water parameters and moderate water flow are essential to prevent sediment accumulation in its valleys, which can lead to tissue necrosis.

Symbiosis

While not known for hosting fish or invertebrates, Honeycomb Coral may occasionally have commensal relationships with small reef organisms that seek refuge within its complex structure. These relationships are generally not as pronounced or specific as those seen in some other coral species.

Habitat

Leptoria phrygia is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with strong light and some water movement, which are conducive to the growth of its symbiotic algae. In the wild, it can be found at various depths, often forming part of the reef structure with its robust skeletal growth.
