Common name: Larger star coral

General information

The War Coral, scientifically known as Favites pentagona, is a species of stony coral that is popular among reef aquarium enthusiasts. It is often referred to as Pineapple Coral, Brain Coral, or Honeycomb Coral due to its distinctive appearance. This coral is characterized by its polygonal corallites which give it a honeycomb-like texture. The coloration of Favites pentagona can vary widely, with specimens displaying a range of hues from green to brown, red, and even purple, often with contrasting coloration on the corallite walls and oral discs.

Care

Favites pentagona is a hardy coral species that can thrive in a variety of tank conditions, making it suitable for both beginner and advanced hobbyists. It prefers moderate to high lighting and moderate water flow within the aquarium. This coral benefits from stable water parameters and the addition of calcium, alkalinity, and magnesium to support its skeletal growth. Feeding is not strictly necessary as Favites pentagona hosts zooxanthellae, symbiotic algae that provide nutrients through photosynthesis, but occasional feeding with microplankton or coral foods can promote faster growth and more vibrant coloration.

Symbiosis

While Favites pentagona does not have the same level of symbiotic relationships as some other corals or marine organisms, it does engage in a mutualistic relationship with its zooxanthellae. These algae live within the coral's tissues and provide it with organic compounds produced through photosynthesis. In return, the coral provides the algae with a protected environment and access to sunlight.

Habitat

Favites pentagona is found in the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the central and western Pacific Ocean. It typically inhabits reef slopes and lagoons, where it can be found at various depths, often forming part of the reef structure.
