Common name: Cliona

Cliona is a genus of demosponges known for their unique ability to bore into calcareous substrates, including coral and limestone. These sponges are characterized by their yellow to orange coloration and can be both beneficial and detrimental in reef aquariums. They play a role in bioerosion but also contribute to the ecosystem's diversity. Hobbyists should monitor their growth, as excessive boring can damage live rock and coral skeletons.
