Common name: Galaxaura

Galaxauraceae is a family of calcified red algae found in tropical and subtropical oceans. Members of this family, such as Galaxaura spp., are known for their bushy, tree-like appearance and can vary in color from deep red to purple. They are photosynthetic and contribute to reef building by depositing calcium carbonate within their cell walls. In the aquarium, they require moderate to high lighting and good water flow to thrive. They can be a unique and attractive addition to a reef tank, but growth should be monitored as they can overtake slower-growing corals.
