The Mermaid's Fan plant, a green calcareous algae found throughout the Caribbean, is used as a decorative plant in the marine aquarium. These plants have short stems that grow out of the substrate or live rock. These plants form a fan like leaf that is oval to round in shape. They are calcareous algae that deposit limestone (calcium carbonate) in their tissues. 

In addition to light, they require sufficient calcium to grow.
