Candy Cane Coral

About

Candy Cane Coral (Caulastrea furcata) is one of those corals that earns its common name honestly. Each polyp sits atop a distinct, tubular skeleton that flares out at the top, and the coloration often runs in pale greens, teal, and creamy tones that genuinely do call to mind old-fashioned candy. In the wild, it ranges across an enormous sweep of the Indo-Pacific, from the East African coast and Madagascar all the way out to Samoa, and from southern Japan down to New Caledonia. It turns up in reef environments from shallow water down to around 40 meters, which hints at just how adaptable this coral is. In the aquarium, that adaptability translates directly into ease of care. Candy Cane is widely regarded as a solid entry point into keeping large-polyp stony corals. It tolerates a reasonable range of lighting and flow conditions without throwing a tantrum, and it tends to expand its polyps reliably when it's comfortable. Colonies grow in a branching, phaceloid structure, meaning each corallite stands separate rather than being fused into a shared wall, which gives a mature colony a pleasingly open, almost sculptural look. It plays well with neighbors as long as nothing is crowding it directly.
