Genus
Common name: Lithophyllum
Scientific name: Lithophyllum
Lithophyllum is a genus of crustose coralline algae commonly found in marine aquariums. These algae are known for their hard, calcareous nature, which allows them to form encrusting mats over rocks and substrates, providing a natural appearance and aiding in the stabilization of reef structures. They are beneficial for reef tanks as they compete with nuisance algae for space and nutrients, and can also serve as a grazing area for certain herbivorous fish and invertebrates. Lithophyllum species require moderate lighting and water flow, and they thrive in stable water conditions with adequate levels of calcium and alkalinity to support their calcification process.
