Common name: Red Algae Family

Halymeniaceae is a family of red algae commonly found in marine aquariums, known for their diverse and often brightly colored species. Members of this family, such as Halymenia and Cryptonemia species, are sought after for their ornamental value and their role in nutrient export. They can provide a natural food source for herbivorous fish and invertebrates, while also contributing to the overall health of the reef ecosystem by competing with nuisance algae. Care for these algae includes providing moderate lighting and water flow, and ensuring they are not overgrown by more aggressive algae species.
