Its coral fin not coral fan! Actually, it IS coral fan! Coral Fans, also known as sea fans, are more correctly called Gorgonians. They are colonial soft corals which grow in a "fan" shape and anchor in sand instead of on hard surfaces as hard corals do. Their primary predators are fish such as, but not limited to, angelfish and butterfly fish. They eat plankton which they capture as it drifts past them.
