Leathers or soft corals are some of the easiest corals to keep. They do not require much in terms of lighting and they grow fast. They will grow tall and sway in the flow with good polyp extension when happy. Most are brown in color, but some are vibrantly colored in either the polyps or their skin. In the wild they grow in nutrient rich waters that they filter feed. Therefore, they do not require such intense lighting. The turbid water they originate from blocks the light from penetrating to their habitat which makes them rely on filter feeding more than photosynthesis.
