Genus
Common name: Bryopsis
Scientific name: Bryopsis
Bryopsis is a genus of green algae commonly found in marine aquariums. It is characterized by its feathery, filamentous fronds that can range in color from bright green to dark green. While it can be aesthetically pleasing, Bryopsis can quickly become invasive, outcompeting corals for space and nutrients. It reproduces both sexually and asexually, making it resilient and sometimes difficult to eradicate. Hobbyists often employ manual removal, nutrient control, and specific herbivorous fish or invertebrates to manage its growth.
