Green Pipe Organ Frag

Tubipora musica, most commonly known as Pipe Organ corals, are soft corals in the Tubiporidae family. Pipe Organ corals have a unique, hard skeleton of calcium carbonate that contains many organ pipe-like tubes. On each tube is a series of polyps which each have eight feather-like tentacles. These tentacles are usually extended during the day, but will swiftly withdraw with any sort of disturbance. The skeleton is a bright red color, but is typically obscured by numerous polyps. Because of this, living colonies are typically green, blue, or purple due to the color of the expanded polyps.
