Common name: Finger coral

General information

Caulastraea tumida, commonly known as the Candy Cane Coral or Trumpet Coral, is a large polyp stony (LPS) coral that is popular among reef aquarium hobbyists for its hardiness and attractive, fluorescent coloration. This species is characterized by its tubular and meandering growth form, with individual polyps extending from a calcified base. The polyps are typically banded with alternating colors, which can range from greens and browns to bright reds and blues under actinic lighting.

Care

Candy Cane Corals are relatively easy to care for, making them suitable for beginners. They prefer moderate lighting and water flow. It's important to provide them with a stable environment, as fluctuations in water quality can cause stress. They can be fed with meaty foods like mysis shrimp or finely chopped seafood, which can promote faster growth and more vibrant colors.

Symbiosis

While not known for hosting fish or invertebrates, Candy Cane Corals may occasionally have commensal relationships with small crustaceans or worms that seek refuge among their polyps.

Habitat

Caulastraea tumida is found on reef slopes and in lagoons, typically in shallow to moderate depths where it can receive ample light. It is distributed across the Indo-Pacific region, from the Red Sea to the central Pacific Ocean.
