Common name: Finger coral

General information

The Candy Cane Coral, Caulastraea echinulata, is a popular LPS (Large Polyp Stony) coral in the reefkeeping hobby. It is known for its hardiness and ease of care, making it a suitable choice for both novice and experienced aquarists. This species is characterized by its tubular branches and bulbous, fluorescent tips which resemble a candy cane, hence the name. The colors can range from green to brown, with the polyps often exhibiting contrasting colors like bright green or vivid blue.

Care

Candy Cane Corals are relatively undemanding when it comes to lighting and water flow. Moderate lighting and low to moderate water flow are ideal to prevent sediment from settling on the coral and to allow for proper feeding and respiration. They benefit from supplemental feedings of meaty foods such as mysis shrimp or finely chopped seafood. It's important to ensure that the food particles are small enough for the polyps to consume.

Calcium, alkalinity, and magnesium levels should be maintained within the appropriate ranges to support the coral's skeletal growth. Regular water changes and stable water parameters are crucial for the health of this coral.

Habitat

Caulastraea echinulata is found in the Indo-Pacific region, typically in shallow reef environments. They are often located in protected areas with moderate light and water movement, which should be replicated in the home aquarium for optimal health.
