The Udoteaceae family, commonly known as Green Finger Algae or Mermaid's Wine Glass, includes calcareous green algae found in tropical and subtropical seas. These algae are characterized by their finger-like or goblet-shaped growths and are often found in shallow waters where they contribute to reef building. They can be a unique and attractive addition to reef aquariums, providing a natural look and aiding in nutrient export. Hobbyists should ensure adequate lighting and stable water conditions to promote their growth.
