Genus
Common name: Sun Coral
Scientific name: Actinostephanus
Actinostephanus, commonly known as Sun Coral or Tube Coral, is a genus of azooxanthellate corals that are popular in the reefkeeping hobby for their vibrant colors and unique feeding behaviors. Unlike many corals, they do not rely on light for photosynthesis and instead require regular feeding with planktonic foods. They are non-photosynthetic and often found in deeper or shaded reef environments in the wild. Hobbyists appreciate them for their ability to thrive in areas of the aquarium with lower light levels.
