The species Hydrolithon is a calcareous encrusting algae that forms an irregular, knobby shaped crust on shallow rocks and coral reefs. Like many encrusting algae, they play an important role in building reef structures by cementing dead coral tissue and fragments together. Species of Hydrolithon are typically a pinkish-purple colored algae that is often found broken off around reef flats and near shore habitats. Fragments can be placed in the aquarium to help seed the marine planted aquarium or reef tank with beautiful coralline algae.
