Common name: Larger star coral

General information

Favites complanata, commonly known as Honeycomb Coral or Brain Coral, is a species of stony coral that is popular among reef aquarium enthusiasts. This coral is known for its distinctive honeycomb-like appearance, with corallites that are angular and share common walls. The coloration of Favites complanata can vary widely, with specimens displaying a range of hues including green, brown, red, and yellow, often with contrasting coloration on the walls and oral discs.

Care

Honeycomb Coral is considered moderately difficult to care for, requiring stable water conditions and moderate to high lighting to thrive. It benefits from moderate water flow, which helps to keep the coral free of debris and provides essential nutrients. Calcium, alkalinity, and magnesium levels should be maintained within appropriate ranges to support skeletal growth. Feeding is not strictly necessary, as Favites complanata hosts zooxanthellae that provide energy through photosynthesis, but occasional feeding with microplankton or coral foods can promote growth and vitality.

Symbiosis

While Favites complanata does not have any specific symbiotic relationships akin to clownfish and anemones, it is part of a complex reef ecosystem where it provides shelter and habitat for a variety of small reef organisms, such as microfauna and some fish species.

Habitat

Favites complanata is found in a variety of reef environments, from shallow lagoons to deeper slopes. It is a hardy species that can adapt to different light and flow conditions, making it a versatile choice for aquarists. In the wild, it is commonly found in the Indo-Pacific region, including the Red Sea, Indian Ocean, and central and western Pacific Ocean.
