Common name: Lesser star coral

General information

The Palau Star Coral, Goniastrea palauensis, is a species of stony coral that is appreciated by reefkeepers for its robustness and the aesthetic appeal it brings to the aquarium. This coral is characterized by its massive, dome-shaped colonies and the intricate patterns formed by its calices. The coloration of Goniastrea palauensis can vary, often displaying hues of brown, green, or even more vibrant colors under certain lighting conditions.

Care

Goniastrea palauensis is considered a hardy coral that can thrive in a range of conditions, making it suitable for both beginner and advanced hobbyists. It prefers moderate lighting and water flow, which helps to keep its surface free of sediment and promotes healthy growth. Regular feeding with microplankton or coral foods designed for LPS corals can enhance its growth and coloration.

Symbiosis

While Goniastrea palauensis does not have any specific symbiotic relationships as notable as those seen in clownfish and anemones, it does host a variety of microorganisms within its tissue, including symbiotic algae known as zooxanthellae. These algae provide the coral with essential nutrients through photosynthesis, which is a key aspect of the coral's energy intake.

Habitat

Goniastrea palauensis is found in the warm waters of the Western Pacific, particularly around Palau, hence its name. It typically inhabits reef slopes and lagoons, where it can be found at various depths, often forming part of the complex reef structure that supports a diverse range of marine life.
