Common name: Anemone coral

General information

The Flowerpot Coral, Goniopora columna, is a species of large polyp stony coral (LPS) that is popular among reef aquarium hobbyists for its long, flowing polyps and striking appearance. It is often referred to as Daisy Coral or Ball Coral due to its shape and the pattern of its polyps. This coral can exhibit a variety of colors, including green, pink, red, and purple, which can add a vibrant touch to any reef tank.

Care

Goniopora columna requires moderate to high lighting and moderate water flow within the aquarium to thrive. It is important to provide stable water conditions and maintain calcium, alkalinity, and magnesium levels to support its skeletal growth. Flowerpot Corals can be more challenging to keep than some other LPS corals due to their specific needs, so they are recommended for more experienced hobbyists.

Feeding is crucial for the health of this coral. Target feeding with fine particulate foods, such as plankton or coral-specific foods, can help ensure that the coral receives adequate nutrition. It is also beneficial to feed amino acids and other coral supplements to promote health and coloration.

Symbiosis

While Goniopora columna does not have any well-known symbiotic relationships like those seen in clownfish and anemones, it is a part of the complex reef ecosystem where it may provide shelter to small invertebrates and fish seeking refuge among its polyps.

Habitat

Flowerpot Corals are found in the Indo-Pacific region, typically in shallow waters on reef slopes or lagoons. They prefer areas with moderate water movement and access to bright light, which supports their photosynthetic symbionts, zooxanthellae, that live within their tissues.
