Common name: Finger coral

General information

Caulastrea curvata, commonly known as Candy Cane Coral or Trumpet Coral, is a large polyp stony (LPS) coral that is popular among reef aquarium hobbyists for its hardiness and vibrant colors. This species is characterized by its tubular and curved skeletal structure, which gives rise to its common names. The polyps of Candy Cane Coral extend from these tubes, displaying a variety of colors, typically bright green, but also in shades of brown, blue, and purple, often with contrasting tips.

Care

Candy Cane Coral is considered a good choice for beginners due to its low maintenance requirements. It thrives in moderate lighting conditions and benefits from moderate water flow, which helps to keep the polyps free of debris and provides nutrients. While it can obtain much of its nutrition from the photosynthetic algae (zooxanthellae) living within its tissues, supplemental feeding with microplankton or finely minced meaty foods can promote growth and color vibrancy.

Symbiosis

While Caulastrea curvata does not have any specific symbiotic relationships akin to clownfish and anemones, its structure can provide shelter for small reef creatures, such as certain species of gobies and crustaceans, which may seek refuge among its polyps or skeletal base.

Habitat

Candy Cane Coral is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with moderate light and water movement, which are conducive to the growth of its symbiotic algae and the removal of waste products. In the wild, it can be found at various depths, often forming colonies on reef slopes and lagoons.
