Genus
Common name: Jania
Scientific name: Jania
Jania is a genus of red algae commonly found in marine aquariums, often referred to as 'coralline algae'. These calcareous algae are important for reef-building and contribute to the stability of reef structures by cementing loose substrate. They display a range of colors from pink to purple and are valued for their ability to outcompete nuisance algae. Jania species require moderate lighting and stable water conditions to thrive and can benefit from the addition of calcium and magnesium to the aquarium.
