Common name: Green Finger Algae

Codiaceae, commonly known as Green Finger Algae or Dead Man's Fingers, is a family of green algae found in marine environments. Members of this family are characterized by their finger-like projections and can vary in color from bright green to dark green. They are photosynthetic and contribute to the reef's primary production. In the aquarium, they can be both ornamental and functional, serving as a natural filtration system by absorbing nutrients like nitrates and phosphates. However, they can grow rapidly and may require regular pruning to keep them in check.
