Candy Cane Coral, also known as Caulastrea, is a type of LPS (large-polyped stony) coral. It is named for its resemblance to a candy cane, with alternating bands of bright colors such as pink, red, green, and orange. It is a popular coral in the aquarium trade due to its hardiness, ease of care, and striking appearance. Candy Cane Coral can be kept under a variety of lighting and flow conditions and prefers moderate water movement and nutrient levels. They are also known for their long sweeper tentacles which can sting other corals nearby.
