Hydrolithon sp.

Species of Hydrolithon are a calcareous encrusting algae that forms a irregular, knobby shaped crusts on shallow rocks, ledges and coral reefs. The coloration is typically pink or purple. They often break apart and colonize and grow the rubble / sand bed near ledges and reefs. Like many encrusting algae, they play an important role in building reef structures by cementing dead coral tissue and fragments together. Fragments are often added to an aquarium to help seed the tank with beautiful coralline algae. Calcium supplementation is required to keep successfully in the aquarium.
