This species is a soft coral but with a 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 retreat with any sort of disturbance. The skeleton is a bright red color, but is obscured by the numerous polyps, which are green or gray in color. They are restricted to shallow waters and tend to live in sheltered areas.They eat plankton.Do not target feed this coral. Add a quality phytoplankton to the water column.This coral can be placed directly on the sand and should have moderate water flow.
