Common name: Green Hair Algae

Scientific name: Bryopsidales

Bryopsidales, commonly known as Green Hair Algae, are a group of green algae found in marine environments. They are characterized by their filamentous and often hair-like appearance, which can add a natural and lush look to a reef aquarium. However, they can also grow rapidly and become invasive, outcompeting corals for space and nutrients. Hobbyists should monitor their growth and maintain nutrient levels to prevent overgrowth. Some species within this order are also known for their interesting symbiotic relationships with marine organisms, such as providing habitats for small invertebrates.
