Genus
Common name: Cladophora algae
Scientific name: Cladophora
Cladophora is a genus of green algae, often referred to as 'green hair algae' in the reefkeeping community. It is known for its filamentous and bushy appearance, resembling tufts of green hair. While some aquarists consider it a nuisance due to its rapid growth and ability to overtake a tank, others use it in refugiums to absorb excess nutrients and provide a natural food source for herbivorous fish and invertebrates. Cladophora species can form symbiotic relationships with certain marine organisms, offering them shelter and food.
